Should companies appoint a CTO ?

Strictly speaking CIO extent is around company information asset management, even if he encompasses often operations management as well. Larger companies which would like to lead processes on its own, may feel better with a second IT manager dedicated to technology, this is a CTO. According to company main stakes, this manager could be outside IT department, where he reports to COO or CEO, or inside and then he reports to CIO.

Productivity in IT Divisions

I thought some years ago that Enterprise information system growth was more or less linear, according to a size factor. But getting experience, I soon discovered that inserting a new application in an existing information system comes to the same thing of creating a kind of turbulence which will take several months before to be stabilized.

Indeed, when counted in a stabilization process, applications may undergo several changes which do not change their initial function points count. Also when enterprises acquire or reengineer some of their information system parts, they use to implement COTS which are difficult to assess in function points. It results that measuring information system size is allways difficult and, even done, it will be a poor predictor for change which is rather related to business optimisation pace.
