This deliverable provides an overview of the requirements engineering work performed in the first half of the project through the iterative process adopted for the COMPOSITION project.The deliverable documents the Lessons Learned and changes in the requirements compared to the information providedin D2.2 Initial Requirements Specification. A further update will be provided in D2.6 Lessons Learned and Updated Requirements Report II, which is due in M28 (December 2018).
The requirements derived from the use cases will be enhanced in aniterative process to assure that the user-centred approachoutlined in the DoAis followedin all phases of the project.Lessons Learned are part of COMPOSITION’s commitment toKnowledge Management, promoting recurrence of successful outcomesand precluding the recurrence of unsuccessful outcomes.Lessons are learned during project research and technology developmentwork, during testing and integrationandas a part of the validation of project prototypes and can thus be learned throughout the project work.The Lesson Learned process adopted by COMPOSITION has six steps:Collection, verification, storage, dissemination, reuseand identification of improvement opportunity.For collection and storage, a repository has been established in the COMPOSITION Confluence Wiki
A total of 26Lessons Learned has been reported in the first cycle. Compared with the list of requirements in D2.2 Initial Requirements Specification, 37 requirements have been added. Not allof these are the result ofthe Lessons Learned; some are technical requirements derived from new or existing user requirements. All requirements have been updated, though the majority not in substance, but rather as a result of adding Custom Labels for various purposes, e.g., filtering/structuring. Fourteen of the original requirements have been rejected.As ofmid-November 2017, the COMPOSITION JIRA repository contains 125active requirements, 8of which have been implemented, while 70have status “Part of Specification”, 17have passed QC check and 30are Open. The group “Part of Specification” covers many requirements that have been partially implemented.All requirements have been reassessed,and if appropriate, Requirement Priority has been changed toreflect the priority of the use case(s) they are part of. With minor deviations within each group, Requirement Priority ‘Major’ includes requirementsin the Tier 1 Use Cases (approx. 64%), ‘Medium’ the requirementsin the Tier 2 Use Cases (approx. 21%), and the rest are Tier 3.With the further development of the COMPOSITION architecture, the list of Components has been extended and now comprises 23 entities. This includes five added components:Building Management System, Data Collection System, Marketplace, Marketplace UIand Service Catalog.Through the “Component” field in the requirement definition Volere template, all requirements are associated with one or more components, providing a structural overview relative to the COMPOSITION architecturedescribed in D2.3 The COMPOSITION Architecture Specification I.
