As a software developer, I'd choose an array to fix these issues. Arrays are like lists that make it easy to store and find information quickly. With arrays, tasks can be organized neatly, making it simple for everyone to keep track. We can put each task's details in different parts of this list, making it easy to see what needs to be done first.

By using arrays, we can avoid the problems caused by spreadsheets. It'll be easier for everyone to update tasks, find information, and make sure the important tasks get done on time. This choice makes things smoother without adding any complications that other methods might bring.
