Critical Path project management planning tool, an inexpensive alternative to Microsoft Project. Calculates Early Start, Late Start, Early Finish, Late Finish, Float (Slack) and identifies Critical Path activities. Calculates and summarizes resource costs. Shows all project data in a "spreadsheet" pattern for ease of understanding. Data may be manually entered or imported from a file or the clipboard. Independent re-sizeable and hideable windows show PERT views and Gantt (bar chart) 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. Up to 1,000 activities. No limit on 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. Individual activities may have their dates "fixed". Pop up "working day" calendar with 200 year range. Easy to change working/non-working days. Activity durations and lags may be specified as either "working days" or "calendar days" - both types may be used in the same plan.~Scale of PERT and Gantt charts are adjustable both on-screen and for printing (to make best use of pages). Reports, PERT charts and Gantt charts may be either printed, or copied to the clipboard for pasting into other programs. Each project may have its own resources list, or master resource lists may be maintained for use across projects. Activities may be grouped into up to three levels, with resource cost summaries available at each level. On a network other users may have read-only access while one user has a file open for exclusive update. Pro version ($69.98 USD) adds features for use with larger plans and in a corporate environment, including resource levelling, costing, administrative detail and enhanced export facilities including the generation of HTML (web page) reports.
