BUS402: Unit 5 Discussion Questions



Consider responding to the following questions by posting your response on the course discussion board for BUS402. You may also respond to other students’ posts.

  1. From Unit 5, what is most useful technique/tool you have learned to control project quality, and why?
  2. In your opinion, what are top three risks for managing a large project? Please give a few examples for each identified risk.
  3. What is Six Sigma? How does the Six Sigma relate to project management practices?


Answer (A):

1A: SQC (Statistical Quality Control), By this method we can understand acceptable variation and control limits of the process/product.


  • Safety risks are common on construction projects.

  • Changes in the value of local currency during a project affect purchasing power and budgets on projects with large international components.

  • Projects that depend on good weather, such as road construction or coastal projects, face risk of delays due to exceptionally wet or windy weather.

3A: Six Sigma is statistical tool that measures process variability and DPMO (Defects per Million Opportunities) 3.4. It is up to management to design a process that will consistently produce products between those limits

  1. Check Sheets, Histograms, and Pareto Charts
    When solving several quality problems, a project manager has to choose which ones to deal with first. One way of prioritizing quality problems is to identify which problems occur most often. These data can be collected through a check sheet, which is a basic form for the user to check every time a problem occurs in the appropriate box or by automating the data collection process using the appropriate technology. Once the data is collected, it can be analyzed by creating a histogram type of frequency distribution chart.
    A true histogram is a column chart in which the column width fills the available space on the horizontal axis and is proportional to the category values shown on thex axis, while the column height is proportional to the occurrence frequency. Most histograms use one width of column to represent a category, while the vertical axis represents the frequency of occurrence. A variation on the histogram is a frequency distribution chart invented by economist Vilfredo Pareto known as a Pareto chart, in which the columns are arranged in decreasing order with the most common on the left and a line added that shows the cumulative total. The combination of columns and a line allows the user to tell at a glance which problems are most frequent and what fraction of the total they represent.

  2. a. Project management risk
    b. Security risk
    c. Internet risk

3.Six Sigma is a quality program that, when all is said and done, improves your customer’s experience, lowers your costs, and builds better leaders.
Six Sigma in many organizations simply means a quality measure which strives for almost perfection. It can be called " Six Sigma " or it can have a generic or customized name, such as " Operational Excellence, " " Zero Defects " or " Customer Perfection. "Six Sigma is a disciplined, data - driven approach and methodology for the elimination of defects (driving towards six standard deviations between the mean and the closest specification limit) in any process –from production to transaction and from product to service.
The Six Sigma DMAIC process (defining, measuring, analyzing, improving, controlling) is an improvement system for existing processes that fall below requirements and seek incremental improvement.
The Six Sigma DMADV process (defining, measuring, analyzing, designing, verifying) is an improvement system used to develop new Six Sigma quality processes or products. It can also be used if an existing process requires more than just an increase.


I also agree

  1. the most useful tool to control project quality is :
    SQC (Statistical Quality Control), Check Sheets, Histograms, and Pareto Charts …

Why: those method which allows to judge the quality with scientific indictors on an interval in a duration of time (without using the emotions, because quality is relative)

  1. three risks for managing a large project
    Safety risks : work accident
    ecological risk : waste water DBO , noise.
    changes in the value of currency : large project=large duration, in the othre side the local currency is very floating from some country.

  2. definition :

Six Sigma is a data driven, customer focused, and result oriented methodology which uses statistical tools and techniques to systematically eliminate the defects and inefficiencies to improve processes.

how :

There are mainly two methodologies of Six Sigma namely DMAIC and DMADV .
