The goal of this activity is to define a technical approach to the system that supports the project
requirements, within the constraints placed on the system and the development team. The architect should do the
following:
-
Work with the team to create an initial sketch of the technical approach to the proposed system
-
Ensure that the technical decisions are adequately captured and communicated
-
Ensure that the team has enough information to understand the approach being taken
The work done here does not seek to produce a detailed and comprehensive technical specification for the system.
Rather, the approach should be to decide the overall technical approach at a high level.
Emphasis should be placed on proving the architecture with working software. If the solution is similar to a system
produced previously (or is a well-known solution domain) then it will probably be good enough to
reference that example as evidence of the feasibility of the approach. In some cases, it may be necessary to develop
one or more prototypes to validate some of the decisions or clarify some of the requirements.
The conclusion of this work should produce just enough information to communicate the architecture to the team and
demonstrate its viability to the customer so that the project can move forward, enabling the
architecture to be refined and baselined.
