Hi, can anyone offer advice

I am nearing the completion of my EA case study report and while I am confident with the content, I am procrastinating over whether I should include a detailed, written timeline? I have already created and referenced a critical path, which illustrates key milestones, but I was wondering if I should include a high level time-frame as well. can you offer any advice? Is this something that needs to be included?

Grateful for any advice.

Thanks in advance,

Freddie
