PlanBee (by Ed Guy) is a critical path project management planning tool.
It calculates early start, late start, early finish, and late finish dates, and float (slack) time, and identifies critical path activities. It calculates and summarizes resource costs.
All project data is displayed in a "sheetsheet" pattern for ease of understanding. Independent re-sizeable and hideable windows show PERT views and Gantt views of the project in addition to the "spreadsheet" view. Activities and links may be set up and edited in either spreadsheet or PERT views or both at once, since all views are kept synchronized.
PlanBee supports up to 1,000 activities. There are no limits on the links per activity (within total of 1,000 links). Links may be finish-to-start, start-to-start, or finish-to-finish to handle overlapping activities. Links may have minimum time lags specified, and individual activities may have their dates fixed.
It also features a pop up "working day" calendar with 200 year range. Activity durations and lags may be specified as either "working days" or "calendar days", and both types may be used in the same plan.
Reports, PERT charts and Gantt charts may be either printed, or copied to the clipboard for pasting into other programs.
This latest version fixes a few bugs found in the previous version.
