What is the purpose?
The Business Architecture Presentation (BAP) aims at providing a high-level description of the product from a business perspective. It may include a description of how the document relates to organizational goals and/or objectives.
The Technical Architecture Document (TAD) addresses architectural aspects like: solution design, infrastructure components, integration requirements, capacity, and security. It includes how the product will meet those goals and objectives.
Why is this important?
- Keeps track of all aspects of an application (or other IT products);
- Plays the role of development, maintenance and knowledge transfer to developers;
- Make information easily accessible and provide a limited number of user entry points;
- Helps users learn quickly, simplify the product and help support costs.
The success of those documents depends on one important element: Reliable and up-to-date data.
To enable this, the Product Manager must ensure the documents reflect current situation, however the collaboration of every member of the IT team is a must
As living documents, BAP and TAD evolve with the product. Suggestions and feedback are encouraged to continuously improve their clarity and usefulness.
