Tasks
As far as each project is unique, all the particular tasks will differ as well, but in a way they are regarding to recognisable generic topics. Despite the intentions and desires of the individuals involved, there are typical issues to be considered, which occur in almost every project.
> potentials and/or intentions
> goals and milestones
> stakeholders and operation
> team and development process
> iteration
The advancing development sharpens the analysis, specifies the planning, improves the process. Each new development phase provides also the chance to re-assess suggesting further applicable conclusions.
In this sense, non of the tasks counts as finalised during the entire development process. And whenever one of the topics is optimised, the impact on the others will be worked into.
