Project Quality Management
PMI quality definition: A characteristic of a process, product, or service that satisfies a clear or implied requirement capability.
Low quality indicates that there is a problem with the product or service, and the product or service with low grade does not necessarily have a problem.
Precision and correctness are not equal. Precision refers to consistency, which repeats a set of measures and is a bit fragmented. Correct means that the correctness measure is very close to the real value. Accuracy does not need to be correct. The very right metric does not need to be precise.
Project cost management includes three management processes:
1, Quality planning: Determine the appropriate quality standards for the project and determine how to meet these standards
2, the implementation of quality assurance: for a planned, systematic quality activities to ensure that all the necessary processes in the project to meet the expectations of stakeholders.
3, the implementation of quality control: monitoring specific project results to determine whether they meet the relevant quality standards, to develop effective solutions to eliminate the causes of quality problems.
Tools and techniques for quality planning:
1. Cost/Benefit analysis: Weigh the relationship between cost and benefit of quality management, so that the benefit of quality management exceeds cost.
2. Benchmarking: Comparing actual implementation or planned project practices with the actual practices of other similar projects
More.
3, experimental design: Through the experiment to find out which variables have the greatest impact on the project results.
4. Quality cost: Refers to all the costs incurred in order to achieve the quality of the product or service. The quality cost is divided into prevention cost, evaluation cost and failure cost.
Tools and technologies for quality assurance:
1. Quality planning tools and techniques: cost/benefit analysis, benchmark comparison method, experimental design, quality cost
2. Quality control tools and techniques: inspection, control charts, Pareto Totou, fishbone charts, scatter charts, etc.
3, Quality Audit: is the other quality management activities of the structural review, is to determine whether a project quality activities in line with organizational policies, processes and procedures of independent evaluation
4, Process Analysis: Through the use of value analysis, activity-based costing analysis and process analysis and other analytical methods to identify the need to improve the implementation of the problems experienced, worthless activities
5. Benchmark Analysis:
Tools and techniques for quality control:
1, inspection: Also known as review, Audit, go to check. The purpose is to determine whether the results are consistent with the requirements
2, Control chart: Also known as the management chart, used to determine whether a process is stable or executable, is to reflect the production process changes over time and the quality of the change of State graphics
3, Pareto chart: Also called arrangement diagram, ABC analysis chart, 80/20 principle, is a column chart, according to the frequency of the occurrence of the event
4, Statistical sampling: is to select a part of the overall income check, the appropriate sampling often can reduce quality control costs.
5, causal map: Also known as causal Analysis Diagram, Ishikawa, Fishbone map. Visually reflects the relationship between the various potential causes or results of the project and its constituent factors with various possible problems.
6, Flow chart: Show the system within the different factors between the role and influence, so as to determine the quality problem may occur somewhere.
7, trend analysis: Based on historical results, mathematical techniques to predict the future results, can be used to track the changes in time variables, often used for monitoring.
8, Straight Square Chart: Also known as bar, quality distribution, rectangular, frequency distribution map, is through the quality of the data processing and collation, find out the distribution of law, judge the whole production process is normal
9, scatter plot: To determine whether there is a relationship between the two variables, the greater the correlation between the two variables, the point in the graph more concentrated, point trend focused on a straight line.
Checklist, Pareto chart is mainly used to identify
histograms, scatter graphs, control charts are mainly used to analyze
Causal analysis and trend analysis can be used for identification and analysis.
