38. The Uncertainties Management Framework: Eliminating Uncertainties from the Process

Building software under current pressure of uncertainties coming from quickly changing global world, increased flexibility of requirements and changing customers’ expectations is a central challenge even using agile methodologies. Sources of uncertainties include requirements, communication process, involved people and the software engineering process itself. This paper is dedicated to revising the software engineering process and presenting ways we could eliminate uncertainties leaking through the process. This is done within the scope of the uncertainty management framework, which is an addition to common project management practices designed to identify, manage and control uncertainties within all stages and aspects of software engineering projects. The process related uncertainties management uncertainties’ elimination techniques include errors injection, stress testing, certainty testing of units, integration, features, usability and transportation components. It also concentrates on handling objects, which are subject for uncertainties like debt, recognised uncertainties, decisions and self-organised teams’ abilities. The software engineering process verification on uncertainties is a multistage process including planning, decision to execute, acting and monitoring, analysis, modification, acceptance and re-evaluation.
