Solve the practice problem based on seven QC tools. Every problem is based on an individual tool. Practice the tools at your own workplace. Design your own process using process flow chart. Collect the data using check sheet for defect analysis. Present the data with help of histogram on paper graphically. Discuss the skewness in the data. Find out which problems need to address first using Pareto chart. Find out the causes of the problem using Ishikawa diagram and try to root out the cause. Control your process with in control limits with help of mean chart and range chart. Identify the problem area at your workplace in your organization. Define the problem, identify the boundaries of the problem. Set the expected time line for the problem to get resolve i.e. when to start and when to end. Using seven quality tools complete the project and show the financial and quality improvement benefits to your organization.

Project Work
Prepare the process diagram of your own work. Identify the valuable items at your workplace. Collect the data of defects occur during the inspection of items. Which defects contribute highest frequency? Find assignable and common causes with help of Pareto chart and control charts. Fix the time limit of the project to complete. Show the financial benefits of your project to your organization.
