Dr. Kaoru Ishikawa, invented the fishbone diagram. Therefore, can be also referred as Ishikawa diagram.
Fishbone diagram is a analysis diagram which provides a systematic way of looking at effects and the causes that create or contribute to those effects.Because of the function of the fishbone diagram, it may be referred to as a cause-and-effect diagram. The design of the diagram looks much like the skeleton of a fish. Therefore, it is often referred to as the fishbone diagram

Twist :- What is 80/20 principle ?
Pareto principle also paraphrased as 80/20 principle is simple effective problem tackling way in management.It says that 20% of your problem lead to other 80 % of problems. So rather than concentrating on the 80% of problem if you concentrate on 20% of problems you can save lot of trouble.So in pareto you analyze the problems and only concentrate on 20% of your vital problems.In projects the first 10% and the last 10% of project form the vital part of project.

How do you handle change request?
Normally change request are handled by preparing a Impact analysis document and then doing re-estimation. Example you have a ongoing project , which has a customer table. Now customer wants that customer to also have addresses assigned to it. So you normally raise a change request and then do a impact analysis of the same. Depending on the impact you estimate and let know the client about the financial aspect of the project. Once client sign off or the upper management agrees to the change request you move ahead with implementation.
