Systems design by 5W is focussed on Data Systems, which naturally includes a large overlap with the application and application hosting areas.
When implementing any new IT system, a thorough, detailed design can be worth much more than it’s weight in gold. When gaps between requirements and delivery are discovered, the reason is not a decision that the gaps were needed! Everyone on a project wants to deliver the best system possible, but without a solid design delivery risk increases.
The design for a new IT system starts with requirements, both functional (which buttons can I push) and the non-functional (what colour are the buttons). The designer’s first decision is to look at the requirements and decide if they will allow a solid design to be created. Redefining, reinterpreting, adding and removing requirements are all responsibilities of the Systems Designer.
The Systems Designer, working with all the project stakeholders, can solve problems, correct mistakes and find those gaps. All before any systems are purchased and installed. The design decisions that are made can yield additional efficiency in operations or reduce hardware and software costs. Or even suggest the use of a Cloud service instead of putting equipment in the data centre.
Designing an efficient IT system that delivers on requirements may yield short term gains, but at the cost of long term much larger gains. The design process therefore also takes into account the business and IT strategy in the form of Architecture. Making sure the strategically important goals of the business and IT organisation have influence on the Systems Design, the Systems Designer plays their part in long term company success.
