V.V.MurthyMember@V.V.MurthyInclude @V.V.Murthy in your post and this person will
be notified via email.Cost of Quality in IT means proportion of cost(effort) spent on Appraisal, Failure and Prevention Cost to Production Cost.
Appraisal cost is cost spent on reviews and testing
Failure cost is rework cost (rework on reviews, retesting, fixing bugs based on customer complaints)
Prevention cost is cost spent on Project Management, CM, defect analysis and prevention activities.A figure of around 30% is advocated to be industry average.(I guess in US)

Ray DainesParticipant@Ray-DainesInclude @Ray-Daines in your post and this person will
be notified via email.We have done some research for information on the cost of defects so we can use decreasing defects in products as our business case. Initially these would all be soft dollars since we do not have an establish baseline to work against. Our source for this is Robert Grady, Practical Software Metrics for Project Management and Process Improvement.
In his book, he stated that his team at HP found the hours to fix defects found in test were as follows
Coding defects that are not found until testing are 2.5 times their cost when they are found during coding.
Design defects are 6.25 times
Specification/Requirement defects are 14.25 timesThe text normalized the data (because they didn’t have fix time metrics either) to be that a coding defect found during code/unit test would take 1 hour to fix. With this assumption, the above numbers then become the hours to fix. Again this would be fix time if the defect is found during test.

Good day!
I would like to have an idea on the definitions (and further explanations) on the recent addition to the classification of costs: appraisal, quality, prevention, and failure costs.
I will appreciate very much whatever information you could provide me. I jsut need them for my report (oral and written) on my MBA class.
Thank you very much!
Hoping to hear from you soon!
Sincerely yours,
Gerlon Joseph R. Magpantay

I’m consultant for UN in Geneva and I need information about cost of quality (cost of achieving good quality : prevention – appraisal) and cost of poor quality (internal failure costs and external failure cost)
Thanks!

Cost of poor quality is how many times do you meet the needs of the customer? How many times do you have to rewrite code? How many times does it pass first time ?
Seems like these measure are quantifiable.0March 5, 2003 at 2:47 pm #83522

Cost of quality in general is the sum total of the following :
1. Appraisal Cost spent for reviews and testing
2. Failure Cost spent in the rework, in case of errors – both internal and external
3. Prevention Cost spent on Project management, defect analysis and prevention activities

There is this big blue stripe on the left. Lots of stuff in there to help you.
You are asking for the traditional catagories. This isn’t complicated and has been around for years. There is lots of information available and you have all weekend.
You also may want to check out the Etiquette Guidelines for the site. I think there is a message in there for you.
Good luck0April 16, 2004 at 7:24 pm #98737Nadia:It depends how much information you want,either you go to the adviced link,or to a special quality book,or you would be satisfied by a summary?? MMAN

Project Management effort can not be considered in Prevention Cost.

Don’t go down that Rat Hole. Taking the text book approach of prevention appraisal etc is the wrong path. Focus on the cost of Poor Quality to address the issues.
I have been in organizations that have religiously tracked the cost of quality right to adding in cost of floor space, the cost of 401 K contributions , the cost of benefits for QA personnel.. Solution get rid of the quality department.
When you track the cost of poor quality you will be addressing root cause issues (rework, engineering evaluation time, testing and finding defects that must be reworked, the time it takes to write bad cose is the cost of poor quality in IT just as in manufacturing)
Think alongthese lines when pursuing actionable metrcis. Remember, “The Metric Drives The Action”.

You are asking someone who posted 5 years ago.
There is a ton of literature on COQ. If you examin the traditional buckets you are going to miss most of it. Look at the 7 forms of waste from Lean and you will get closer.
Just my opinion.
