Thought of the day by William Edwards Deming
The management of a company that makes furniture, doing well, took it into their heads to expand their line into pianos. Why not make pianos? They bought a Steinway piano, took it apart, made or bought parts, and put a piano together exactly like the Steinway, only to discover that they could only get thuds out of their product. So they put the Steinway piano back together with the intention to get their money back on it, only to discover that it too would now only make thuds.

What Is The Important Feature of Interface Inheritance ?
The interface inheritance enforce you to implement a method with a given signature, but it doesn’t enforce you how to implement it or to use some default behaviour!
Every Manager Deserves His Developers
I am rephrasing an old political proverb, but it’s true. If a manager ask you to release four days earlier, after he has promised you to postpone the release date with a week probably the chaos is so big in teams with this kind of managers that you can’t expect any quality from the software product which is developed. The quality is result of software process development instead of shortcuts searching in order to release the product earlier.
If I have to define the first law for managers, I could say that the chaotic “thinking” in manager’s head is multiplied by ten in developers’ heads. Also we shouldn’t forget the fact that manager is only one but the developers, and testers are more so we have explosion of chaos which interfere in the team!
Advice for managers : Dear manager please think in advance at least a week ahead!

Cohesive Software Design – Observations
This week I have been explaining about cohesion using materials from Prag Pub Magazine and realized something ultra very simple. The definition of cohesion is “proximity should follow dependency” which make me see that cohesion(proximity) is function of dependency. So cohesion = f(dependency) and if we want to follow Single Responsibility Principle you can just iterate by every member in the class and if you can see some lack of dependency probably you should move the member in another class. I see that this is a mechanical approach for class construction but sometimes helps.
