Weekend reading: Software projects planning and estimation

,

Here are some links to interesting stuff on software estimation and projects planning for weekend reading and watching.

  • Your Will Suffer From Power Laws. There are some things, which are the way the are, and you can not change them, even if you want. You can not spit upwind (at least, not with desirable result); you can not make an apple fall up, when you release it. So with our projects there are some things, which we simply have to learn to live with.
  • 10 Deadly Sins of Software Estimation webinar by Steve McConnell. Interesting presentation about art and science of software estimation. A lot of references to statistical studies, which give good food for thought.
  • Software estimation considered harmful? Alternative point of view on software estimation as presented by Steve McConnell. DeMarco and Lister refer to study, which suggest highest productivity on projects, which were not estimated at all. Does this mean we should not estimate our projects?
  • Evidence Based Scheduling. Practical approach to software estimation developed at Fog Creek.
  • Agile Management for Software Engineering: Dealing with Uncertainty. A chapter from great book by David Anderson. Something always goes wrong. The problem is that we do not know what and when, yet we have to plan and execute our projects. This chapter of David's book can help you.

Finally, a tip from Leo Babauta of ZenHabits to a project manager, who needs clear mind, when  project is derailed, for finding peace of mind.

Wimbledon - perfect uncertainty management

[caption id="" align="alignright" width="180" caption="New roof at Wimbledon"]New roof at Wimbledon[/caption] For years I've been using Wimbledon tournament as an example of really good uncertainty management: with all those games taking very different amounts of time, unpredictable rains (in 2008 man's final was interrupted twice) - it is a scheduling nightmare. Yet, man's final always happens on the 2nd Sunday of tournament (except for 2001 when it was raining on Sunday and final was delayed till Monday).

Wimbledon is scheduled for 13 days, beginning on a Monday and ending on a Sunday with the middle Sunday a designated rest day. The five main events span both weeks, but the youth and invitational events are held mainly during the second week. Traditionally, there is no play on the "Middle Sunday", which is considered a rest day. However, rain has forced play on the Middle Sunday three times in the Championship's history: in 1991, 1997, and 2004. On each of these occasions, Wimbledon has staged a "People's Sunday", with unreserved seating and readily available, inexpensive tickets, allowing those with more limited means to sit on the show courts. Additionally, if the tournament is not completed by the end of the second Sunday, all remaining matches are postponed until "People's Monday".

Tight rules, uncertain conditions - great execution!

Now the problem with rains is fixed at its roots: roof at Wimbledon's Centre Court. This does not fix the problem complete, as other courts are still under open skies, but weather area on Wimbledon's home page gradually becomes less relevant.
