Let’s say you work 100 days on a project. How many days would each phase of your process (requirements analysis, specification, etc.) take?
I’m interested also in the ratio of specific activities in every phase, such as writing tests, back-end coding, front-end coding, visual design, database design etc.
Many thanks!
EDIT:
Just to make things clear, I’m not talking about web site design – I’m interested in more ‘serious’ web development, such as custom business web applications. I know, everything depends on the specifics of each project, however I suppose the ratios could be roughly the same from project to project.
EDIT2:
As Helen correctly remarked, this question is really hard to answer, since projects can be so different and so can be teams. To make it more specific, let’s say you have a team of four developers – two of them for back-end work, one for front-end programming and one for design & html/css coding (one member of the team acts as a project manager) and you are supposed to develop StackOverflow.com site.
We’re running agile scrum projects, so we typically run all these activities in parallel. So while I cannot answer your exact question, I can give you some ideas of the ratios we have found to be effective:
4-5 developers can be served by one client side programmer (html/css), one on-team tester and one interaction designer (works with the customer to design wireframes). A team like this typically needs a 50% graphic designer for most applications, but your mileage may vary there. Then there’s project manager, and there’s all sorts of other stakeholders that are not part of the core development team.
In the development team you normally have a couple of developers who are sharp on client side development and similar amount on the back-end. These staffings also tend to reflect resource usage 😉 Testing is an integral part of development as well as the efforts of the on-team tester.
Your local conditions may of course vary, but these numbers are just to give you some idea.
