Knowledge Area 6 Project Quality Management

  • Quality planning
  • Quality assurance
  • Quality control

Conformance to requirements and fitness for use

Pareto Diagrams - a histogram, ordered by frequency of occurrence, that shows how many results were generated by type or category of identified cause. Rank ordering is used to guide corrective action - the project team should take action to fix the problems that are causing greatest number of defects first.


Cost of quality
  • prevention costs
  • appraisal costs
  • failure costs.
Prevention refers to keeping errors out of the process, whereas inspection refers to keeping errors out of hand of the customer.

Attribute sampling determines whether the result confirms or not, and variables sampling determines the degree of conformity.

Tolerance determines if the result falls within acceptable range, but control limits are used to determine if the process is in control.

Just in time Manufacturing is a process that continuously stresses waste reduction by optimizing the processes and procedures necessary to maintain a manufacturing operation. Part of this process is JIT purchasing or inventory where the materials needed appear just in time for use, thus eliminating costs associated with material handling, storage, paperwork, and even inspection.

Better quality provides
  • Improved Cost Effectiveness
  • Better Customer Satisfaction
  • Increase in Productivity

Design of Experiments is a statistical method that helps identify which factors might influence specific variables.

Rule of 7 > If 7 or more consecutive data points fall on one side of the mean, they should be investigated

Control chart the best tools to look for results out of control.

Standard deviation refers to Distance of measurement from the mean.

Process adjustments involve immediate corrective or preventive action as a result of quality control measurements. In some cases, the process adjustment may need to be handled according to procedures for integrated change control.

The objective of a quality audit is to identify lessons learned that can improve performance of this project or of other projects within the performing organization.

This documentation is personal study notes I prepared during my PMP certification study. The source for this study notes is partially from PMBOK 2000, PMP Exam Cram 2, and www.pmstudy.com. I only take notes on knowledge areas that I thought was useful for me. In the real exam, the contents covered are much broader and more difficult than any reference books. So I think real life experience is very important.

Crocs sandals

Suddenly one special looking sandals get popular. The brand is Crocs. It even opens a brand store at Marina Square. The design idea is from Dutch wooden shoes, I guess. A pair of Crocs sandals is sold at around SGD 50. The price is justified for what it is made of - Croslite. Based on Crocs website, "Croslite™, a proprietary Closed Cell Resin (PCCR) which is NOT plastic NOR rubber. Croslite™ is closed-cell in nature and anti-microbial, which virtually eliminates odor. it is an extraordinary impact absorbing resin material developed for maximum cushioning. its closed cell properties resist odor, inhibits bacterial and fungal growth and are non toxic. this versatile material can be worn next to skin and be cleaned with just soap and water." However, it really looks like made of plastic or rubber, and the design is unique. Replica comes. they are sold at SGD 20, SGD 10, SGD 5 depending on quality.

A couple days ago, a sex video clip about a female Chinese graduate student Wang Ting Ting (王婷婷) was posted on the internet. Just as it is about to cool down, another sex video clip pops. It is a sex clip of a Singapore Nanyang Polytechnic student . The video clip was stored on her cell phone. Someone stole it and posted the video clip on the Internet. This is a breaking news. It is even reported on major Singapore and Malaysia newspapers. Now we have so many cool gadgets. It is a breeze to shoot photos/videos, and share them on the internet. Everyone, even dog, is on the internet waiting for breaking news. Be careful when you do something secret or stupid. It may appear all over the world, live!

Prostitutes in Singapore

Singapore is very realistic about this issue. Prostitution is legal. The famous red light zone is Geylang area. I heard Hong Kong officials are considering to legalize this business in HK also. Singaporeans are not allow to work as prostitute. Maybe also SPR. The prostitutes are mainly foreign workers from poor countries in SEA area, such as Indonesia, Thailand, India, Malaysia, not from China. They come under special 2-year working pass, and must pass the health exam, yes, to prevent STD such as HIV, AIDS and so on. The brothels are mixed with normal resident houses. The brothel's house number is red lighted. The price is ranged from SGD 50 to SGD 200. Illegal sex workers are also around, and in some massage clinics. A very recent fatal case and newly effective government policy make a special social group - Chinese accompanying mom for studying kids a hot media buzz again.
