Well, a table with one sheet for logging your progress, like what where when and how much, adding screenshot links etc.
Then another sheet that takes this data through calculations and time limitations, and a sheet for nice output data with fancy progress and resource charts, that will tell you what can you build, out of whos wrecks, in what time, what would the expenses be and so on.
Maybe I am overestimating sheet possibilities, but this is what could be done to ease your management.
