I reached a point at which I need to write about software project requirements in my thesis. Unfortunately I am not sure whether to go with past or present tense for this section.
In this section I have various sentences like:
Once X was automated -- or -- Once X is automated The second step required the generation of X -- or -- The second step requires the generation of X
The requirements are fulfilled so past tense seems appropriate to me. On the other hand the section should only introduce the requirements and not include information about the project status.
Are there any rules (or guidelines) that one can follow in such cases?
