To save money on your project and time consuming on your project, you picked randomly few deliverables and check the quality of those deliverables. It is frequently used when you are working on a bulk volume where time does not permit you to cross check each and every deliverables. Apart from the above-mentioned tools there are some other tools available that can be used as a quality tool like statistical sampling. Like due to one defect another defect is created maintaining a relationship. It is like trying to trace the relation between two variables. It is an important tool to be used in so many project management activities. Through it you can assess a particular process and analyze the potential quality problems. It shows how the systems or processes flow from beginning to end and how are they related to each other. You have to see the patterns of the variations. If you need to assess the variable you need to check your progress chart. It shows what problems are in your project. It displays data in the form of bars and columns. It is a graphical representation showing a visual impression of the distribution of data. There is also upper and lower specification limit which are decided by the end customers only. If seven variables are found in one side of the mean, it is known as rule of seven and the project will be treated as ‘out of control’. It represents the middle of the range of an acceptable variation. There is a line in the middle of the control chart which is known as ‘mean’. If the variables are within the limit, the project will be treated ‘in control’. That upper and lower control limit is decided by project manager and other stakeholders. Instead you can decide your upper limit and lower limit of acceptance. It is not possible to standardize the sizes, weights of the deliverables. As a project manager you should detect an error which can resolve your maximum problems. Pareto recommends that this tool can be very useful if you are getting many errors frequently. It is based on the Joseph Juran’s 80/20 principle. This is frequently used when you are in hurry and you have to reduce the defects… as a project manager you should know by which factors you are getting more problems and document it and try to find out a way to remove these defects as by removing the same defects you will be able to reduce maximum problems. Search for the main reason and try to reduce the maximum problems. Pareto Chart:Ĩ0% of problems are due to 20% of the root causes. ![]() ![]() If you are managing a long term project you should use this quality tool at the utmost. By analyzing these you can get the root cause of the defects, that’s why it is also known as root cause analysis. Whether the problem is from management or the problem is from skill set of the people. Whether the main issues are from hardware or it is from the software. It is frequently used to find the root causes of the defects. It is popularly known as Fishbone diagram (as it looks like a fishbone) or sometimes known as Ishikawa’s diagram. Let me explain you these tools one by one: Cause and effect diagram: As a project manager you should pick the correct tools for the quality control and for this you need to know the basic attributes of all the quality tools mainly Ishikawa’s seven basic tools of quality. ![]() You should be aware which quality tools to be used and when? By whom and how? Many project managers fail to control the quality in their project as they chose the wrong tools and techniques for their project. ![]() As a project manager you should be aware of all the tools and techniques used. As a project manager I believe you all use various tools and techniques to control the quality in your project.
