This is on 4th chapter and the beginning of the 5th chapter of the book.
Howard Podeswa has stressed in those chapters, the importance of interviews. While in practical work life, we hold interviews to gather the requirements, he has stressed that confirming the requirements is more important. This can reduce many costly mistakes which can occur later.
Another new thing that I met while reading the ebook was that he talks about Business Object Oriented Modelling (B.O.O.M)
In different organizations, the system development life cycles differ. One might be using waterfall model while another uses spiral model and so on.But, mostly the phases in these are,
• Initiation
• Analysis
• Execution
• Test
• Close Out
During the Initiation and Analysis sessions, the BOOM occurs. Initiation means getting a rough cut of the business case. In analysis, the detailed requirements are elicited.
In the initiation phase main deliverable is: Business Requirement Document (BRD).Opportunity Evaluation, Project Vision and Scope and Product Vision and Scope are also some deliverables.
The BRD’s main components are business use-case specifications including business use case diagrams, role map , system use-case diagram and initial class diagram, describing key business classes. Howard has presented a detailed template for BRDs which he has advised to adjust according to the project
