Use a company culture and team working and propose a single project for improvement and change that can address them, and report on this. You should be able to demonstrate:
The nature of the problem: disjointed communication in a typical start up enviroment
Your proposed solution
How that solution will benefit the organization (a typical tech start-up) and its stakeholders, i.e. how it will create value
Resources required, and the cost-benefits trade-off
Ethical and governance issues that the project may involve
