You don't need Access Control because it's just an excel file and whoever has the file has the planning model. In most organizations like this, there's only like 5 or 8 people who all work together on a team, so it's not like 50-some people who are separated. Excel is a tool, a tool that you use to get things done. I mean even programming solutions have issues such as Knight Capital Group's $460 million loss due to mistakes in their code and deployment processes. Planning modules does not mean Operational modules. It's a big difference/jump between the two.
Again, these are all tools. What's important is how you use it and how do you properly validate these calculations. the thing you also need to understand is that no critical infrastructure planning is perfectly to-the-dot numbers. Our systems are far too complex, built off of human operational decisions, and have so many unknown losses that planning modules are based on scenarios. Also we're talking about thousands of these agencies around the world and their critical infrastructure planning teams are mostly 5 to 8 people. The current agency I'm working with has hired around 3000 employees to operate the systems but only 5 or so are really in-the-deep running these models and building these plans.
These people are not programmers. They spent their time learning about resource planning, mathematics, operation theory, physics, and engineering. Excel is an incredibly user-friendly tool that lets them automate a tremendous amount of their tasks. They're all very intelligent and can definitely learn how to code, but that takes their time away from more critical skills and tasks they need to accomplish.
The most important solution to the problems you've stated is the workflow. You setup a proper workflow, and risks of these problems should be minimized.
