	1. Specification (Requirements Analysis)

		Determine what needs to be accomplished; write a clear
		(often formal) description.
	2. Analysis

		Study the requirements; describe the functionality of the system; 
		determine relationships among system components; understand 
		the logic of the processes involved.
	3. Design

		Design data structures and component structures to match those 
		relationships; formulate algorithms to implement the processes.
	4. Coding

		Translate the above into a programming language
	5. Testing & Evaluation

		Check the software system :
		Is it correct?  Are there any errors?
		Does it accomplish its purpose?
	6. Maintenance

		Make changes based on experience with the software system 
		and on changing requirements.
