7. IUID in Practice—Industrial Development

It is faster and more successful if management roles in the projects (e.g., Product Owner and Scrum Master) are filled with interculturally experienced team members right from the start.

SPICE’s “process capability model” includes 6 “process maturity levels”: 0—incomplete, 1—performed, 2—managed, 3—established, 4—measurable, 5—optimized. A short and action-relevant introduction to SPICE can be found in Heimgärtner 2016. SPICE is explained in detail in ISO 15504. The successor and general standard for process assessments are ISO 330XX. When SPICE is mapped to SCRUM, some of the generic practices of the process attributes 3.1 and 3.2 can be largely or fully achieved.

Different interpretations of the “agile manifesto”, which is very abbreviated here because it is short and concise, are often represented by different methods (such as SCRUM, XP, Lean Driven, Kanban).

The contextual interview therefore always has a contextual reference and is therefore often referred to as “contextual inquiry”.

Principles of “design thinking”, for example, can be used here. In this example it could be determined, for example, when, where, how and for how long a user enters data into the navigation system.

This distinction increasingly disappears with the use of integrated localization tools (see Sect. 7.4.4).

Further information on the IIA Tool can be found in Heimgärtner (2007) and can also be obtained directly from the author and at URL=https://​www.​iuic.​de.

This means as independent as possible of a subjective (and thus culturally influenced, i.e., culturally dependent) interpretation by a person. In this way, the usability engineer is able to make statements about culture-dependent findings on the basis of the evaluation of culture-independent methods.
