Systems analysis and design
Many time we heard about agile in software development. Many times authors wrote that agile provide us to fast and cheapest solutions. It is true but not all the times. Chaos Report (see Standish Group) show us, that is not true all the times.
Few comments…
Generally small projects are not a (big) problem..
Waterfall vs. agile: first one method consume many more time than second one, but we have no time to ‘big analysis’. Second one mean ‘working too fast’, and effect is more prototyping mean cost increasing… many time mean: cancel project before finish caused by budget:
A waterfall is not a solution, but agile is not a good remedy for it. A common problem in software design is system size and complexity:
How to improve quality and chance to succeed software project? We need really good person to business analysis role and only one. More than one person in a first stage, mean more problem with merging parts to one completed and unambiguous requirements document :
Disciplined agile, what is it? Using models in agile, why and for what? Modern system analysis and design is not a waterfall and not a agile style? It is science method used for software engineering . Discover the MDA and patterns as a wand for your success in software projects. See the system as a architecture .
