Systems Methodology

This represents a value-rich model of how purposeful system developments may take place. It also has powerful connections with the human information processing system.

"Necessity is the mother of invention; invention is the father of necessity."

Vision	The mission statement! Explicit declaration of the purpose of the system. But what does it all mean?
Meaning	Recognition of the intended: environment market context scope These have to be recognised before it is possible to start any meaningful planning.
Planning	Proper preparation and prior planning prevents piss-poor performance. Project planning should include: risk analysis integrity development methodologies interfaces with the environment, structure, methods. scenarios, rehearsal, role-play. test plans All of this work is necessary to fully realise what the system constraints may be.
Constraints	System constraints from such things as: government legislation, business rules, limitations of technology e.g. hardware and software tools Procedures for quality standards With these known, full-scale development of the product or system can go ahead.
Development	Getting closer; some tangeable results will start to emerge at this stage. analysis and design prototyping programming testing, testing, testing All this needs to be done before the product/system can be produced
Production	Implementation of full-scale production, leading to action that completes the cycle.
Action	Do it! Delivery and fullfillment of the original vision.
