Hi Arline,
I am sorry to hear about the recent unfortunate news from PMI about your application being rejected. Do not despair; this happens more often than you think, and you have the chance to resubmit your application again.
As you know, the project manager's role and responsibility is to plan, organize, and direct the completion of a specific project. For the PMI to approve your PMP application, you must provide all the proof, including in-depth context with brief practical details about the projects you led and your role. You don't necessarily have to give an example of your projects as the PM of set projects; however, you must demonstrate how you applied project management skills and tools (i.e., PM software such as ClickUP, Monday.com, etc.) to complete your projects. You should avoid only listing tasks with PMI buzzwords without further explanation and context to support them.
Your revised project description above is good overall. I have the following small suggestions :
1) I suggest you make your project description personal using "I" instead of sounding like a resume. Also, you can state which methodology (Waterfall, Agile, or Hybrid) you used for your projects and which one your organization prefers.
2) Demonstrate at a high level the task you were involved in, led, and directed in PMI language with one or two brief examples describing the process you took to increase the chance for your application to get approved. I think using examples, if possible, will help elevate your application.
3) Use as much PMI language as appropriate throughout your application. Avoid just using PMI language like buzzwords without context. You want to be brief with your project's summary, while providing enough vital information.
I hope this was helpful to you. I wish you all the best of luck; you can do it!
