I recently needed to consider the state of a System Architecture and consider the changes likely to be needed over time. Thus, I was trying to produce a “Roadmap” for the architecture into the future. The challenge was that the future is uncertain. Some items can be planned for, and others are dependent on the way the business and technological environments develop. These developments can be considered to be the product of various “forces” playing out in the environment of the system. How then can you address this complexity?

A performance model will be full of assumptions and estimates, and yet it is necessary to make important design decisions and capacity choices based on its predictions. This means that it will be necessary to check that it is correct, known as validating the model. Continue reading ‘Validating a performance model’ »
A new computer system goes into production and starts with a pilot. A set of load testing is done to make sure that the live user levels can be supported, with some problems. These problems are resolved and maybe some extra hardware purchased to ensure performance at live volumes is acceptable, and then a full roll out is started. The project team are on site for the first few weeks, and resolve the problems that are experienced initially. The system is handed over to support along with a development team member and then the project team is disbanded. The support team are left to complete the roll out process, and the development team member moves on after a while. Continue reading ‘The case for predicting the future’ »
