If you are following the feedburner feed you shouldn’t do anything (i.e. if I did everything right you should be reading this post :) ) You are welcome to visit the new site on...
Read MoreSAF – Deployment – What to do when the architecture seems stable?
The last activity of SAF is deployment of the architecture. This step can make the difference between an ivory-tower architect and one whose designs are actually used in real software projects. Deployment of the architecture actually means two things Verification and feedback loop. – making sure the architecture is actually the right one. Governance – making sure that the...
Read MoreSAF – Evaluation part II – the “Formal Methods”
Onthe previous post on architecture evaluation I talked about evaluating a candidate architecture in code. This post is dedicated to evaluation on paper. I remember one system I was working on, I was keen on making the architecture asynchronous and message oriented (it was all circa 2001 by the way) However, I was new on the team and my role (as the project’s architect) wasn’t well...
Read MoreSAF – Architecture Evaluation – Evaluation in Code
In SAF - Architecture Evaluation (Introduction) I said there are two approaches to evaluating a software architecture. This post talks about the first approach – evaluating an architecture in code. POCs The first evaluation-by-code tool is the Proof of Concept (POC for short). Building a POC is about building a minimal amount of code implementing a focused area of the architecture or...
Read MoreSAF – Architecture Evaluation (Introduction)
I said in “what’s Software architecture” – architecture is both an early artifact and it also represents the significant decisions about the system – or to sum it up ”Architecture is the decisions that you wish you could get right early in a project.” (Ralph Johnston*). That is exactly why I made evaluation one of the key steps in SAF. We want to...
