Description:
|
Defines what technology components
will be used to construct the solution, what different applications will
be constructed for the solution, how each application will be broken into
components and built, and key design elements. This focuses more on the
technology needs of the IS organization and less on the needs of the business
unit.
|
Risk & Impact:
|
This task defines what applications
will be built and how they will be componentized and organized. Inadequate
specification could lead to a less flexible design and constrained distribution
leading to a less optimized system.

Questions Asked:
|
1.What
are the key, independent functional areas (e.g. Business activities vs.
maintenance activities)?
2.What
are the commonalties between functional areas (e.g. both business and maintenance
applications need to logon)?
3.What are the more business-generic aspects of the application (e.g. logon)? 4.How should the components or behavior be layered to provide flexibility? |

Application
Component Architecture – A diagram showing the individual applications,
the individual components and their relationships to each other.
Application
Design Notes – A brief narrative or outline describing the design of
the application including its key design elements.
