Integrated.Requirement.Analysis.
After finishing the interview phase, and when all functional and quality requirements
have been obtained, information is consolidated, yielding a single requirements
document that will be input for the later phases of design. In this process we
need to establish priorities and solve conflicting requirements. Thus, we define a
set of priorities for each functional and nonfunctional requirement. Conceptually,
this priority indicates the level of importance of the requirement. Priorities are assigned
a number between 1 and 5 as follows: optional requirement = 1; low importance
requirement = 2; intermediate importance requirement = 3; high importance
requirement = 4; mandatory requirement = 5. When two conflicting requirements
have the same priority, a high-level user must decide which one will be considered.
Once conflicts are solved, requirements validation is performed.
???. Data.source.selection.and.document.generation:.With the information collected
in the previous phases, interviews are carried out with data producer
users in order to determine the quality of data in the data sources, with the goal
of matching user requirements and available data.
