7. Method and Tools for System Design for Sustainable Energy for All

Design Orienting Scenario [11], a tool to inspire and inform designers towards possible futures on specific topics, has been adapted [1, 12] to Sustainable Product-Service System (S.PSS) applied to Distributed Renewable Energy (DRE). The tool, (from now on) Scenario presents four visions narrated as interactive videos accessible through a navigator file. The Scenario is a tool to inspire designers and stakeholders to design radically new social, economic and technical solutions and as co-design strategic conversations and facilitating creative processes among different actors (Fig. 7.1).

The tool allows to watch the videos to inspire towards Sustainable Product-Service System (S.PSS) applied to Distributed Renewable Energy (DRE) solutions. The tool presents four visions within a polarity diagram of two axes. The horizontal axis defines who is the customer of the narration final user (B2C), or as small entrepreneur/small business (B2B). The vertical one defines the offer: a Distributed Renewable Energy generator (e.g. solar panel system plus its appliances such as storage, inverter, wires, etc.), or the sum of both the Distributed Renewable Energy generator and the related Energy-Using Products or Energy-Using Equipment (e.g. phone and television are Energy-Using Products; woodworking machine, sewing machine are Energy-Using Equipment). Each vision is presented through one short video (around 90 s) that shows peculiar narration, highlighting the key points of the vision (e.g. stakeholder interactions, ownership. Three sub-videos (around 30 s each) help to achieve the understanding of a wider range of opportunities than presented in the video of the vision; these three sub-video show: all the possible offer and the related payment modality; (2) all the possible stakeholders that can be involved and their possible interactions; (3) all possible sustainability benefits (environmental, socioethical and economic).

The Scenario requires the use of a slideshow software (e.g. Open Office PowerPoint). Each video and sub-video can be watched separately or a central button is available to run the whole videos as one. The suggestion is to watch a main video first and after the related sub-videos, then, the second main video and so on.

The result is a set of ideas favouring creative processes and co-design activities towards concepts of Sustainable Product-Service System (S.PSS) applied to Distributed Renewable Energy (DRE).

The tool is available for free download at www.​lenses.​polimi.​it. The tool has been designed to be used in workshops and co-design sessions, therefore a projector is preferable. The time required to visualise all videos is approximately 15 min.

Strategic Analysis (SA) template, a tool to collect and process the background information necessary to the generation of a set of potentially sustainable solutions. On the one hand, it aims to understand the existing situation and find out more about the existing proposers, the socio-economic context in which they operate and the dynamics (socio-economic, technological and cultural macro-trends) that influence that context; on the other hand, it aims to process information by which to steer the designing process towards the generation of promising sustainable solutions (Fig. 7.2).

The tool is an editable template based on five sections:

For each section, a set of subsections with questions and/or guideline is available to support its completion.

The Strategic Analysis (SA) template can be printed or edited in its digital version. Each section and sub-section can be filled separately and according to the aim of the activity.

The result is a collection of information about design brief, context and the related access to energy, existing system as well as its sustainability (environmental socioethical, economic).

The tool is available for a free download at www.​lenses.​polimi.​it. To be used in its digital version, an editing software is needed (e.g. Open Office Word). The time required could last from hours to days, according to the detail of the information.

Sustainable Energy for All Idea Tables [13], structured on the SDO toolkit,¹ it is a tool to generate ideas for S.PSS applied to DRE solutions, it is based on six idea tables with guidelines. To the guidelines of each table are connected 15 case studies to be used as examples. For each of the case study, a card has been developed. The Sustainable Energy for All Idea Tables is presented as a co-design tool to generate (sustainable) ideas facilitating the creation process (Figs. 7.3, 7.4 and 7.5).

The tool allows the generation of (sustainable) ideas for S.PSS applied to DRE solutions. Six idea tables with criteria and guidelines are available to orientate the design process. Fifteen case studies and cards can be used as supportive examples associated to the guidelines.

Each table refers to a criterion (and includes specific guidelines) to design (sustainable) ideas for an S.PSS applied to DRE concept. The criteria are the following and they are described with their guidelines in Chap. 5:

The Sustainable Energy for All Idea Tables tool could be used with two modalities.

Each table needs to be used singularly and presents a series of guidelines which are suggestions to orient the design of (sustainable) ideas in relation to a specific offer. Aside from the guidelines, an empty space is left to post ideas. After reading the guidelines, it is possible to use the post-it (digital or in paper) to write ideas. As general rules: no ideas are wrong; there is not a compulsory number of ideas to be written; the ideas need to be at system-stakeholders’ interaction level and not at product level, e.g. offer the use of a bike (sharing) with a payment based on time of use to bring kids to school, but not a bike itself.

Each case study represents an existing case of S.PSS applied to DRE in relation to a specific guideline. Each card is made of a short description with the key information: customer, provider, type of S.PSS, offered products (and related ownership), offered services (and related provider), what is paid, DRE source, DRE system configuration (front of the card) and a visualisation of the stakeholder’s interactions through an Energy System Map,² where the interaction representing the guideline is highlighted.

The results are new sustainable ideas (written in the post-it) of Sustainable Product-Service System (S.PSS) applied to Distributed Renewable Energy (DRE). The most promising ideas are transferred into the Innovation Diagram for S.PSS&DRE to generate the concept (more about in paragraph 2.6.7, where the tool is presented).

The tool is available for a free download and in copy-left at www.​lenses.​polimi.​it. The tool has been designed to be used in workshops sessions, therefore is good to work on it collectively, though it could be used even by one person only. It is available both with digital version which could be used through a pc with or without a projector (suggested if the group is composed by more than 3–4 person) or as printable one (suggested to be printed as A3–A2). The case study cards are available in digital and printable version, the suggestion is to print them to facilitate the exchanges between the group. The time required is approximately 60 min (10 for each idea table).

The tool [13] is developed to support the design of Distributed Renewable Energy (DRE) systems, as well as to guide the evaluation of the energy demand and need of the designed system concept, and to assess the best system configuration and estimate the energy production potential (Fig. 7.6 ).

The tool is composed of six main worksheets (in one excel file):

The tool integrates databases and websites to get data on the local availability of renewable resources (e.g. Geographical Assessment of Solar Resource irradiation) (Figs. 7.7, 7.8, 7.9 and 7.10).

First step is to define the energy load/need (worksheets 1) to determine the (potential) energy consumption of the system. To support the definition of the energy need in relation to appliances is possible to choose from the database of appliances (worksheet 2). After, it is possible to compare the energy load/need emerged, with the energy production potential of the DRE system designed (if any) to verify correspondence of energy need and energy availability. A second step is to size (or resize in case of existing) the DRE system according to the energy need to be satisfied. To do this, first step is to define the local renewable energy resource to be used: sun, wind, water and biomass (worksheets 3–4–5–6), and then to dimension the system according to the energy/load need. A final check is possible (worksheet 1) comparing the energy load/need and the energy production potential which has to (in average) correspond to the energy load/need.

The result from the E.DRE tools is a preliminary sizing of new DRE systems, according to energy need and locally available resources.

The tool is available for a free download at www.​lenses.​polimi.​it. It is available in digital version which could be used through a pc or a projector and requires internet connection to reach information from the online databases. The time required is approximately 60 min.

The tool [5‐7] can be used for classifying S.PSS models applied to DRE, positioning company’s offers, analysing competitors in the market and exploring new opportunities. The tool can be also used for generating new concepts of S.PSS applied to DRE.

The tool is composed of the Innovation Map, the Archetypal Models Cards, Stakeholder Cards and a set of Concept Cards. The Innovation Map has been built as a classification system for S.PSS and DRE models [2] (see Sect. 4.​4). The tool was built as a polarity diagram that combines different types of S.PSS models with the DRE energy systems and it can be used to position companies and new concepts according to the type of business model and the technology involved.

The vertical axis distinguishes the different types of S.PSS models, i.e. what is being offered to customers and what do they pay for. The different S.PSSs types on the Innovation Map help users to classify energy solutions based on what is the focus of the offer (product, use or result-oriented) and what is the payment structure (e.g. pay-to-purchase a product with financing services, pay-to-rent or pay-per-energy consumed). The vertical axis also encompasses ownership structure and environmental sustainability potential.

On the horizontal axis, the different types of DRE systems are illustrated: mini kit, individual energy system, charging station, isolated mini-grid and connected mini-grid. The horizontal axis encompasses also the type of target customers addressed in the S.PSS solution. It ranges from individual target (including the individual use of energy for households, entrepreneurs, productive activities, community buildings), to community target (which includes altogether a number of households, and/or productive activities, community buildings, public spaces, etc.) (Fig. 7.11).

The Archetypal Models Cards collect different types of S.PSS applied to DRE with corresponding case studies and a system map that illustrates how the system work (see Sect. 4.​4) (Fig. 7.12).

The Stakeholders Cards aim at detailing actors and competitors involved in the energy scenario and at understanding their roles and responsibilities. This type of card can be used during the strategic analysis of competitors (see next section) (Fig. 7.13).

The concept Card aims at providing a template for generating new concept directions of S.PSS applied to DRE and it includes type of offer, network of providers, products, services, customers and payment channels. It can be used during the idea generation session (see next section) (Fig. 7.14).

The tool can be flexibly used in different stages on the design process, from the strategic analysis (e.g. positioning company’s offers and its competitors) to the idea generation and concept development phase.

The Innovation Map can be used for different purposes in the Strategic analysis and Exploring opportunities stages.

The tool can be used to position a company’s offerings according to the value proposition, type of energy system and target customer. Users can write down the company’s offering on post-its (one offering per post-it), and place them on the map. The positioning should follow the type of S.PSS, i.e. product, use or result-oriented according to the specific payment structure and ownership model, and the type of DRE system involved in the solution. It should be highlighted that one company may have multiple offerings, and therefore these can be positioned on various parts of the Map (see Fig.3.​1) (Fig. 7.15).

Following the same criteria, companies operating in the selected context can be positioned on the Innovation Map, possibly using another colour of post-its. Users may want to focus on a specific technology (e.g. only mini-grid) or map all actors operating in a specific geographic area. If necessary, other offers that are not Product-Service Systems can be positioned in the box on the right-hand side of the Innovation Map (Non-PSS offers). These can include for example sale-based offers (e.g. sale of solar lanterns) or other complementary energy products (e.g. bioethanol fuel) (Fig. 7.16).

To gather a deep understanding of the energy scenario, the tool can be used to detail the stakeholders that are providing energy solutions in a selected context and what roles and responsibilities they have. This phase aims at going more in-depth in analysing the target market by detailing the previously mapped solutions. The Stakeholder Cards can be used to define the actors involved and the roles they have. This phase can help users in understanding the main socio-economic actors operating in the energy sector in a specific area (Fig. 7.17).

Having detailed the existing energy situation for the chosen context, users can focus on identifying promising areas to explore. This can be carried out but circling an area they want to focus on (Fig. 4.​3). It could be a specific technology (e.g. individual energy systems) or a type of offering, or both. Areas that have not been explored by competitors in the same context may be a good starting point for tapping promising markets. It must be highlighted that the tool does not provide indications on how to identify promising areas. Instead, it acts as a framework to trigger and stimulate discussion among the design team (Fig. 7.18).

The Innovation Map can also support the design of new concepts of S.PSS applied to DRE. For this purpose, the Concept Cards can be used to write down ideas, starting by describing the general type of offer users intend to provide. Then, the corresponding number of the Concept Card can be positioned on the Map, following the same criteria used to map companies’ offerings. At this stage, it is advised to generate several concepts, they will be selected and refined in the second moment.

Then, for each concept, the card should be filled out by writing down ideas on customers, products and services, stakeholders and payment modalities. At this stage, the aim is to consider the several elements of the design solution, without necessarily going into detail (Fig. 7.19).

Once the phases of strategic analysis and concept generation are completed, the Innovation Map should provide a visualisation of existing businesses/competitors, stakeholders involved, promising areas to explore and new business concepts. This can be the starting point for a discussion within the company’s management team about which concepts are more promising, what influencing factors need to be considered and to eventually select one or more options for further detailing.

At the end of the process, the Innovation Map provides a picture of the current situation (position of company’s offerings, competitors and stakeholders involved) and a selection of promising areas to be explored. The Innovation Map also provides a first idea generation support to identify new business opportunities (Fig. 7.20).

The tool is available for a free download at www.​lenses.​polimi.​it and on www.​se4alldesigntool​kit.​com. The tool has been designed to be used in workshops and (co)design sessions, therefore, it is preferable to print it in a large format (at least A1). The time required for using the Innovation Map can vary, but a minimum of 2 h is suggested to complete all design phases.

The tool [3, 7, 8] can be used to support the generation of ideas on specific aspects of S.PSS applied to DRE (network of providers, customer, products and services, offer and payment channel), and to bring an initial concept idea to a detailed concept.

The tool is composed by a Design Framework, a set of Cards and a Design Canvas (Fig. 7.21).

For each building block, the Framework provides a series of questions that should guide the user in the design process. For example, the network of providers building block presents the following questions: ‘Who are the actors involved in the provision of the energy solution? What are their roles and responsibilities? What partnerships can be established?’ (Fig. 7.22).

Each group of cards is provided with an Intro Card that specifies what information you can find in there and how to use it. A general structure of the elements contained in the cards is illustrated below (Fig. 7.24).

The Design Framework and Cards has been developed to be flexibly applied according to users’ needs. In particular, the tool finds application for:

This section illustrates how the Design Framework and Cards can be integrated in the SD4SEA design process and what outcomes can arise from its application.

The tool can be used in the beginning of the Exploring opportunities stage to support brainstorming sessions to generate ideas on the various building blocks of the Design Framework. In other words, the tool can be used when there is not any agreed concept direction, to inspire idea generation looking at the various aspects of S.PSS applied to DRE. Ideas then can be reviewed, selected and combined to develop initial concept directions. The idea generation process does not have to follow a specific order; it is possible to start from any building block.

The main application of the Design Framework and Cards is the detailing of an initial concept idea. In fact, the tool allows to go in-depth in all the building blocks and to generate ideas for each of them. This activity can be carried out after having used the Innovation Map to generate a concept idea, or if the designer/s has already a draft idea of the business model they would like to detail. After the idea generation, ideas are reviewed to select the most promising ones to be integrated into a detailed concept design.

The tool can also be applied to brainstorm on a specific aspect of an existing S.PSS solution. For example, a company already delivering a S.PSS solution may want to improve the payment modality, and they can use the tool focusing only on the Payment Channels building block to get inspired by the guidelines, case studies and suggestions (Fig. 7.26).

The use of the tool does not require following a specific order for the idea generation. Users are encouraged to decide the starting point they prefer. The design process can be, therefore, carried out in an unstructured way, for example, browsing Cards and using the Framework as a reference, and then writing down ideas on post-its, positioning them on the Canvas (Fig. 4.​11).

At the end of the design process, all elements of S.PSS applied to DRE should be detailed with selected ideas (among the ones generated in the activity), and the questions provided on the Canvas should be answered. The tool can be used in combination with other tools and resources; in fact, concepts generated with the tool might require further evaluation in terms of financial sustainability, technical feasibility, presence of appropriate regulations and other external factors.

The tool is available for a free download at www.​lenses.​polimi.​it and on www.​se4alldesigntool​kit.​com. The tool has been designed to be used in workshops and (co)design sessions, therefore a printed format is preferable: the Design Framework should be at least A2, the Design Canvas can be printed in A1 and the Cards can be printed on A4 and folded.

To use the Design Framework and Cards, we suggest from a minimum of 2 h to grasp the most essential aspects; to a 8 h to go in-depth and detail every building blocks. We also suggest that the idea generation is carried out in multidisciplinary teams to maximise innovation potentials.

The Stakeholder System Map tool, developed by [7, 9] to visualise the network of stakeholders in a S.PSS solution, and their interactions (in terms of flows of goods, materials, services, money, work and information), has been adapted to be specifically used for S.PSS applied to DRE The Energy System Map [4] is presented as a visualisation tool, with its specific set of icons, flows and rules that aims at supporting (co)designing and visualisation of S.PSS applied to DRE models.

It is, therefore, a support tool for

The tool allows the development of a graphic representation showing

The tool is a representational tool that can be described as both codified and progressive. It is a codified system in the sense that it can be considered a ‘technical drawing’ representing the actors involved in a S.PSS in a standardised and comparable way. It is progressive in the sense that it is a ‘formalisation-in-progress’ of the solution actor map giving an increasingly accurate picture of the project as it develops.

The tool is composed by a set of icons (to represent socio-economic actors as well as the various physical and intangible elements of the S.PSS), arrows (to represent the various types of flows/interactions between the actors), a template to be used in the design process and a set of rules for the visualisation and a set of rules to visualise them. Icon is characterised by colour-coding and a short text describing the actor, product or activity (Figs. 7.27 and 7.28)

The tool requires the use of a slideshow software (e.g. Microsoft PowerPoint, or the equivalent in Open Office), but a printed version can also be used. The tool is based on some specific rules to be followed (Fig. 4.​12) that aim at standardising each S.PSS + DRE model.

Each actor is represented by one icon, made of three elements.

The nature of the flows between the different actors is marked by different arrows (Fig. 7.24):

The Energy System Map can be used at various stages of the designing process.

In the Strategic analysis, it can be used to describe

In the System concept design, it can be used to

In the Design System details, it can be used to

The result is a map that shows the various socioeconomic actors that take part of the system and their interactions (in terms of material, information, money and workflows). This map becomes more and more detailed as the project evolves.

The tool is available for a free download at www.​lenses.​polimi.​it and on www.​se4alldesigntool​kit.​com. The tool has been designed to be used in workshops and (co)design sessions, therefore, a printed format is preferable. Alternatively, the tool can be used in its software version (Microsoft PowerPoint), which allows users to modify icons and personalise their Energy System Map. The time required to generate a System Map is approximately 30 min. For more complex systems additional time may be required.

The Innovation Diagram for S.PSS&DRE [13], is a tool to analyse competitor’s energy solutions; as well as to orient the design of new S.PSS applied to DRE concept. The tool allows selection and clustering of (environmentally, socioethically, energy) sustainable ideas within polarity diagram, and starting the design of new S.PSS applied to DRE concepts. Furthermore, it provides the characterization of the designed S.PSS applied to DRE concepts through a set of labels and suggestions. The Innovation Diagram for S.PSS&DRE is presented as a co-design tool favouring a deep understanding of the solution/concept while facilitating collaborative processes and discussions among stakeholders (Figs. 7.32 and 7.33).

The tool is composed by three worksheets for existing energy solutions, for competitors’ energy solutions, for new concepts. Each worksheet is based on the following structure: title + proposer + unit of satisfaction + polarity diagram + profile (with labels) + short description. The worksheet for new concepts includes post-it to stick new ideas from the Sustainable Energy for All Idea Tables tool. Two additional worksheets with labels and instructions are available to fill the profile section of the tool.

In each of the worksheet the following could be found:

Profile (with labels) the profile presents a table with empty spaces to be filled with the following key information regarding the energy offer³:

The labels are divided as per the profile key information (see above) and offers for each of them a series of variable solutions, e.g. for the customer there are several labels such as, community, household, etc., the same is for all key information. To facilitate the use of the label a question and guideline for each key information is provided.

The short description is no more than 200 characters, to be used to present the solution/concept highlighting the main innovation and sustainability value.

Post-it

Post-it are available in the worksheet for new concepts to stick new ideas, or ideas from the Sustainable Energy for All Idea Tables contained both in a dedicated file and in the Sustainable Energy for All section of the SDO toolkit tool.

The Innovation Diagram for S.PSS&DRE tool requires the use of a slideshow software (e.g. Microsoft PowerPoint, or the equivalent in Open Office) or can be used in the printed version. According to the aim of the design activity, the corresponding worksheet/s need to be used.

First, write proposer/s name/s of who is working on it and the unit of satisfaction (e.g. access to energy, in the rural area, for home use). Second, position the existing and the competitor’s offers (in the two worksheets) in the polarity diagram according to its customer and offer boundaries. As general rule is not compulsory that the offer correspond to a single position (e.g. B2C–B2B), if the case, is possible to locate the offer in the middle. Third, fill the profile following the instructions provided to copy/paste the labels. Considering that an existing or competitors’ offer is not automatically an S.PSS or is not necessarily offering products and/or services, some spaces in the profile could remain empty. Finally, write a short description of the offer emphasising innovation and sustainability problems.

First, write the (draft) title of the concept that is going to be designed, then write the proposer/s name/s of who is working on it and the unit of satisfaction to be met (e.g. access to energy, in the rural area, for home use). Second, copy and paste the most promising ideas from the Sustainable Energy for All Idea Tables tool and position them in the polarity diagram. Creative discussions among the proposers will address the way to position the ideas according to customer and offer boundaries (the two polarity axes). As general rule is not compulsory that one idea corresponds to a single position (e.g. B2C–B2B), if the case, is possible to locate the idea in the middle and to decide after. Third, read all selected ideas and cluster them to create one/more concepts, some ideas if not interesting anymore can be excluded. Then, select the most promising S.PSS applied to DRE concept emerged and fill the profile following the instructions provided to copy/paste the labels. Finally, check coherence of the whole information and write the short description of the concept emphasising innovation and sustainability values. Follow up with discussion on the emerged S.PSS applied to DRE concept.

The Innovation Diagram for S.PSS and DRE can be used in the Strategic Analysis and System concept design stages of the design process.

The result in the case of existing or competitor’s energy offers is their characterisation, where the lack of S.PSS applied to DRE offers emerge.

The tool is available for a free download at www.​lenses.​polimi.​it. The tool has been designed to be used in workshops sessions, therefore, if the digital version is used a projector is preferable. In the case, the paper version is preferred suggestion is to print the worksheet as A3 or A2.

The time required to analyse existing or competitor’s energy offers is approximately 20 min; in the case of the design of an S.PSS applied to DRE concept is approximately 30 min.

Concept Description Form for S.PSS and DRE [13] is a tool to visualise and finalise the description and characterization of a new S.PSS applied to DRE concept. The Concept Description Form presents a worksheet where to visualise key information, facilitating a deep understanding of the concept while presenting it among (existing—potential) stakeholders (Fig. 7.34).

The tool is composed of one worksheet with the following fields: proposer, title, unit of satisfaction, short description, profile.

The Concept Description Form for S.PSS and DRE requires the use of a slideshow software (e.g. Microsoft PowerPoint, or the equivalent in Open Office) or can be used in the printed version. First, is needed to write proposer/s name/s of who is working on the concept, together with title and the unit of satisfaction met. Second, write the short description of the designed S.PSS applied to DRE concept emphasising innovation and sustainability values. Third, fill the profile table with text for each key information. Follow up with discussion on the emerged S.PSS applied to DRE concept and refine as needed. Generally, if the Innovation Diagram for S.PSS and DRE have been used, most information can be taken there and updated according to the newest version of the concept.

The result is the summary of an S.PSS applied to DRE concept, facilitating the concept definition while presenting it among (existing—potential) stakeholders.

The tool is available for a free download at www.​lenses.​polimi.​it. The tool has been designed to be used in workshops sessions, therefore, if the digital version is used a projector is preferable; in the case, the paper version is preferred suggestion is to print the worksheet as A2 or A1. The time required to summarise an S.PSS applied to DRE concept is approximately 20 min.

The Stakeholders Motivation Matrix [10], a tool to visualise motivations of the stakeholders, has been updated [13] as a collaboration between DIS Research Group of Politecnico di Milano (Italy), Makerere University (Uganda) and TU Delft University (The Netherlands) becoming Stakeholders Sustainability and Motivation Table. It is presented as visualisation tool aimed to identify/show: motivations and contributions of each stakeholder; sustainable (economic, environmental, socioethical) benefits from each stakeholder; this facilitating involvement process and strategic conversations addressing various (existing and potential) stakeholders (Fig. 7.35).

The tool is made of four worksheets: the table, two worksheets with guidelines to define environmental and socioethical benefits, a worksheet with icons.

For each stakeholder is asked to fill all columns: stakeholders: stakeholder icon and stakeholder name; motivation: motivations for the specific stakeholder to be in the partnership of stakeholders/contribution to the partnership––contribution given by the stakeholder to the partnership; environmental, socioethical, economic benefits–– benefits brought from the specific stakeholders in relation to sustainability. Follow up with a preliminary discussion addressing (existing and potential) stakeholders. To fill the environmental and socioethical benefits two dedicated worksheets are available.

The Stakeholders Motivation and Sustainability Table can be used in the System concept design and Design System Details stages of the design process.

In both cases, it can be used to verify and facilitate the involvement process and to orient strategic conversations addressing (existing and potential) stakeholders.

The result is an informative table of motivations, contributions and potential benefits as way to orient strategic conversations addressing (existing and potential) stakeholders.

The tool is available for a free download at www.​lenses.​polimi.​it. The Stakeholders Sustainability and Motivation Table requires the use of a slideshow software (e.g. Microsoft PowerPoint, or the equivalent in Open Office) or can be used in the printed version, in this case, printed materials and a pen are sufficient. The tool has been designed to be used in workshops sessions, therefore, if the digital version is used a projector is preferable; in the case, the paper version is preferred suggestion is to print the worksheet as A3 or A2. The time required to fill the information is approximately 10 min for each stakeholder.
