Interesting Microsoft Research paper on the efficiency and effectiveness of TDD

From cLabs Blogki:


http://research.microsoft.com/en-us/projects/esm/nagappan_tdd.pdf


Case studies done on 4 development teams (three at Microsoft, one at IBM) that have adopted TDD. Results of the case studies indicate that the pre-release defect density of the four products decreased between 40% and 90% relative to similar projects tha tdid not use the TDD practice. The teams subjectively said that they experienced a 15-35% increase in initial development time after adopting TDD. Very interesting paper.

While some people are actually fond of doing statistics homework, many others dread when it comes along, both for its difficulty and the amount of time it often takes to complete this work.

  22. Schroeftransport De moderne transportschroeven zijn een directe afgeleide van de 'Schroef van Archimedes'. Met deze uitvinding van Archimedes konden vloeistoffen, slurries of poeders kunnen worden getransporteerd. In een buis is een spiraalvormige schroef vast aan de buis gemonteerd. Zowel de buis als de schroef draaien dus rond. De verplaatsing is het gevolg van de draaiende beweging van de spiraalvormige schroef binnenin de buis. Het transport gebeurt meestal opwaarts, maar ook toepassingen voor horizontaal transport bestaan.
