I know of a long-standing program where a particular format of project status chart has been in use for more than a decade. It was originally created to status the assembly sequence of a complex device (M) and thus acquired the name "M" Assembly Sequence Chart (MASC).
Although this chart format has since been re-purposed to status all sorts of projects with complicated dependencies, the acronym has stuck and MASC is all I know it by. Does this type of chart have a common industry name? I'm trying to learn more about it and look for tools to help me create automatically and status them.
I know it looks similar to a classic PERT chart, but I see a few key differences and am wondering if these particular specializations are codified in their own variant. For example:
- The PERT chart focuses on spans, which is useful for generating a schedule and understanding the critical path. The MASC is used once the schedule has been established and is used to show progress against dates.
- The MASC uses color codes to show progress, rather than schedule data like critical path
- In practice, when estimated or actual start and finish dates don't line up with the plan the old dates are not removed but
struck-throughand the new date put above (although this isn't shown in the example).
