5 Planning Phase Activities Domain Analysis Process [2]  Identification of existing, future and potential applications;  Identification of domain features;  Evaluation functions;  Domain modeling;  Features and domain documentation;

6 Planning Phase Activities New Activities:  Identification of the domain requirements based on the features;  Identification of the domain use cases based on the features;

7 Artifacts – Features Model Document It involves the information that the Feature Matrix [3] does not focus on; The Planning section identifies the information from the preparation phase: stakeholders, objectives, constraints, market analysis and data collection. The Application section involves the domain applications, i.e., the existing, futures and potential ones; The Feature Model section shows the final model for the domain;

8 The Domain Documentation section has the following information about the domain:  Description, defining rules, example system, documentation and genealogy; The Features Documentation section has the following information for each feature of the domain, except the root one (“Game”):  Semantic description, rationale, example application, constraints, variation points and priority. Artifacts – Features Model Document

9 Artifacts - Feature Model

10 Feature Model - divided

11 Feature Model - divided

12 Artifacts – Feature Matrix It shows the domain features in a hierarchy form; Contains the results for the evaluation functions;

13 Artifacts – Domain Requirements Document Involves the requirements identified for the domain based on its features; The relationship between the features and the requirements are n X n; We included the “Associated Features” field to the requirements document;

14 Artifacts – Domain Use Case Document Involves the use cases identified for the domain based on its features; The relationship between the features and the use cases are n X n; We included the “Associated Features” field to the use cases document;

17 Strong and Weak Points Strong Points  Team commitment;  Reuse of information from other teams;  Coherent and well defined division of the activities;  Collaborators with experience in this kind of development;  Reuse of OXE’s templates; Weak Points  Game domain unknown to the majority of the team;  Lack of experience with domain analysis – difficult to identify what should a feature and should not  Lack of documentation about the evaluation functions {which ones to use, what are they meant for...}

18 Learned Lessons Necessity of a domain expert for the identification of the features; Definition of the relation among features X requirements X use cases; Domain X Requirements – Application X Requirements; Feature documentation could become extremely complex as the domain grows, although its is helpful to identify if the feature is really a part of the domain; Huge feature models becomes too complex and are not very representative, losing focus of its functionality {understand more easily the domain}; Modification of the IXI’s templates.
