EXAMPLE: Estimation of Unknown Unknowns

Project are often complex and unpredictable events happens along the road of execution. We try to anticipate risk and opportunities in a world that is unpredictable (stochastic) and we do our best to make the project predictable (deterministic).

  • Often people use most of their time analysing project work packages and Know Unknowns (Something we know – that we don’t know, that is have to solve, e.g. questions, requirements etc.).
  • Why not look into Unknown Unknowns, something that we don’t know that we don’t know! And get close to the real world.

This video gives a rather simple method for estimation of (some) Unknown Unknowns making you budgets and plans more robust!

Here is an introduction to the method. Listen to how you can use the method.

The method comprises for example:

  • Budget analysis
  • Time schedule analysis
  • Business case analysis
  • Project port folio analysis
  • Time study analysis

During the analysis risk, assumptions and opportunities are emerging in combination.

It’s a Danish spoken video with subtitles. The subtitles can be automatically translates to e.g. English by YouTube.
