Chapter 1. Introduction to Patterns for
e-business
The role of the IT architect is to evaluate business problems and build solutions
to solve them. The architect begins by gathering input on the problem, an outline
of the desired solution, and any special considerations or requirements that need
to be factored into that solution. The architect then takes this input and designs
the solution, which can include one or more computer applications that address
the business problems by supplying the necessary business functions.
To improve the process over time, we need to capture and reuse the experience
of the IT architects in such a way that future engagements can be made simpler
and faster. We do this by capturing knowledge gained from each engagement
and using it to build a repository of assets. IT architects can then build future
solutions based on these proven assets. This reuse saves time, money, and
effort, as well as helping ensure delivery of a solid, properly architected solution.
The IBM Patterns for e-business help facilitate this reuse of assets. Their
purpose is to capture and publish e-business artifacts that have been used,
tested, and proven to be successful. The information captured by them is
assumed to fit the majority, or 80/20, situation. The IBM Patterns for e-business
are further augmented with guidelines and related links for their better use.
