Thanks Dr. Stumptner and Dr. Naik for sharing your views. I read very carefully the article   published by Dr. Naik etal  . It is most interesting article. I have also attempted its application in one of my publication.

In quality management in the pharmaceutical industry and research it is often used to identify in advance any possible problems that can negatively influence the use of analytical chemistry in pharmaceutical projects. You collect a group of experts and do a moderated brainstorming session, drawing an Ishikawa diagramm as you discuss (there are some free programs like XMIND that are very useful for that). That can then by used almost 1:1 to generate a FME(C)A risk analysis table. Any identified risks above a certain threshold are mitigated before you even start the first measurements.  That significantly improves the quality of the analytical results.

The trick is to get the right experts in one room at the same time without external pressures from other projects for a set amount of time - risk management is not a job for the hasty and/or inattentive.

Dear Rathore sir., on this question Mr.  Willibald Stumptner has shared his view and highlighted the importance of Ishikawa Diagram (Fish bone Diagram). This Ishikawa diagram is one of the Lean laboratory tool used to reduce or eliminate waste (Please see the attachments for details Page No 188 -189) which are likely to occur in any event (in your case; Analyical Chemistry ) by various factors like 6M's viz;  Methods, Measurements, Machine, Man, Material and its Mother nature, so create a diagram and list out all possible errors which could come across in analytical chemistry, per say to carry a test or detect a particular compound, so with this Ishikawa diagram one can trace out  errors at initial stage itself and it will save your resources...!!! faster and efficient results one can get it.

The Ishikawa diagram is an important tool during the preparation of an uncertainty budget  in accordance with GUM; its proper use is described in the 2012 edition of the Eurachem document, often referred to as QUAM:

Thanks  Dr. Heydorn for sharing your views.The Ishikawa diagram has great potential and need to be explored for diverse applications.

Thanks Dr. Kaj Heydorn, Laxmana Naik and Willibald Stumptner  for sharing your views.

Ishikawa diagram was popularized by Kaoru Ishikawa, who pioneered quality management processes in the Kawasaki shipyards, and in the process became one of the founding fathers of modern management.

It is considered one of the seven basic tools of quality control, also known as a fishbone diagram because of its shape.

Management people are using it Strategic management also.
