- 5. CONTROL CHART Control chart is used to determined the business processes are in a state of control The Control Chart is a graph that shows how the process changes over time. Analysis of the control chart indicates that the processes are stable and there is a little variation and is under control then there are no changes required for the process control parameter.
- 7. What is Check Sheet This sheet helps in identifying all the possible errors and has the flexibility to add more sources of error based on practical experience. These are then used for recording data about the errors, which is eventually used for analyzing the operational issue.
- 9. Pareto Chart • The Pareto chart is a quality improvement tool that is based upon the Pareto principle, the principle that 80% of an outcome comes from 20% of its inputs. • Introduced by Vilfredo Pareto, an Italian engineer and economist. • It is basically a bar chart showing how much each cause contributes to an outcome or effect. The length of each bar represents the “cost” (in time, number, or money) of each cause, and the bars are arranged longest to shortest to visually emphasize the most significant or principal causes.
- 10. Histogram • A histogram is a graphical representation of data. • It can offer a powerful analysis of our problems. • Why use a histogram as a quality tool? 1. Displays data in an easy-to-interpret graphical manner 2.Shows frequency of occurrence of data values 3.Reveals the centering, variation and shape of the data 4.Illustrates the underlying distribution of the data 5.Enables future prediction of process performance
- 11. Flowchart • A flowchart is a diagram which represents a workflow process, algorithm, or a step by step process connected by arrows in different directions. • These flowcharts are used for the representation of organizational structures, Login System, document work process flow, billing transaction flow etc.
- 12. Cause and Effect diagram • Cause-Effect is also known as Fish-bone diagram,was first n used by Dr. kaoru Ishikawa of the university of Tokyo in 1943.Cause and Effect diageam can help in brainstroming to identify possible causes of a problem and in sorting ideas into useful categories.

- 14. It was established in 1968 as part of the Tata group of companies. It has grown to be the largest software and management consultancy organization in southern Asia. TCS first implemented quality control procedures in the early 70s. TCS introduced structured systems analysis and design processes in 1982 In 1992, TCS decided to adopt ISO 9000 as a quality norm
- 15. Between 19s TCS had to make more struggle for enhancement. Figure. The reduction in rework. Each data point indicates the rework effort as a percentage of the total effort, for one project.
- 16. In 1996 TCS decided to adopt the Carnegie Mellon University Software Engineering Institute’s Software Capability Maturity Model ( C.M.M ). It got much success in the software field after advancement of C.M.M. The objective of achieving CMM Level 4 at TCS-Seepz required enhancing the metrics program through statistical process control. The SEPG created control charts to monitor schedule slippage, in-process defects per component, and maintenance field errors. The project teams and the SEPG used run charts to track review effectiveness, measured as the percentage of defects detected in peer reviews before testing. After applying statistical control chart, company got much success in the field of software and technology.
