PERT == Program Evaluation and Review Technique
Can a wiki be used to capture the typical project planning? Any interest out there in discussion?
The following represents some half formed thoughts...
  • The page name is the activity name
  • Estimates exist as page attributes...
    • Optimistic=1w
    • Nominal=2w
    • Pessimistic=4w
    • computed Expected=(O + 4N + P)/6

A page must only talk about it's required inputs (dependencies) i.e. it's predecessors. It must not talk about it's successors in any direct fashion.

Predecessors & Successors can be listed/summarized using QueryPlugin functionality.

Partial PERT diagrams can be shown in-wiki based on queries and transforming results into GraphVizPlugin syntax for display (imap=true is great here)...

An set of TAG's to indicate that a page is to be considered part of the PERT scope... PROJECT tags are probably a very good idea here too...


A WikiForm for the initial creation of pages (ease initial data entry).

Plugins needed:

  • PertData - Sets arbitrary attributes to be used by the pert (resource, progress, risk, value, etc). Just prettied up sanity check syntax around [{SET attrib=value}] directives.
  • PertEstimates - Takes in estimate data and computes the Expected, may use a heuristic to "pad" a single point estimate to the required 3 point estimate) saves values much as PertData would (just a syntax sugar/helper).
  • PertSummary - Output a table summarizing the relevant data for a single PERT-ITEM
  • PertDiagram - Query the linked PERT-ITEMs generate GraphViz syntax and create a abbreviated pert graph.

Very important that the PERT data in-wiki not be viewed as a replacement for traditional project management tools (MS-Project etc). So...

  • PertExport - Query all PERT-ITEM + PROJECT tagged pages, generate a TAB/CSV plaintext list suitable for copy+paste into MS-Project. Must generate the predecessor "task numbers" for all items to preserve linkages between 'tasks'. This could be useful to 'dump' to MS-Project for 'analysis' or 'better' charting. Also preserves the work investment should use of the wiki fall into disfavor for project management purposes...


Thoughts anyone? I have need to develop a schedule for a 10 internal + 3 external project that is likely to be 8-12mo long... I hate the MS-Project mindset... I'm looking for an alternative means... Wiki As PERT seems doable... Anyone have any other ideas? Or interest in playing with this concept? --JohnV
