- Quality refers to the performance and usability of the final product produced
- Quality planning ensure superior quality product delivered
- The quality planning involves identifying what constitutes quality for the project and devise methods to measure it
What Is Quality?
- The International Organization for Standardization (ISO)
defines quality as “the degree to which a set of inherent characteristics fulfill requirements” (ISO9000:2000). - Other experts define quality as
- Conformance to requirements means that the project’s processes and products meet written specifications
- Fitness for use means that a product can be used as it was intended
Quality items
- The first step in quality monitoring is to determine what needs to be measured
- Things to measure to access quality can be based on:
- Regulatory requirement (e.g. Government authority specifies that Internet provider needs to ensure 99% availability for its internet subscriber)
- Dependent on project (e.g. Improved customer satisfaction, ease of use of software, better web surfing speed)
Quality measurement
- After determining what are the things that will affect quality, we need to know how to measure them
- Method used to measure whether standard is met include:
- Metrics – defines how something can be measured. (E.g. A server can process 100 web request per minutes)
- Checklists – list out the tasks to be completed and states the results (E.g. 1: Hardware installed 2: Customer satisfied with prototype)
Quality Metrics
- A metric is a standard of measurement
- They allow organizations to measure their performance in certain areas and to compare them over time or with other organizations
- Examples of common metrics used includes failure rates of products produced, availability of goods and services, and customer satisfaction ratings
Quality Checklists
- A checklist is a list of items to be noted or consulted
- Verify that a set of required topics or steps has been covered or performed
- A single project can have many different checklists, such as for:
- Interviewing project team members
- Selecting suppliers
- Ensuring a room is ready for training
Cost of quality
- Cost of quality refers to the work needed to achieve quality product
- To ensure quality, added work needs to be done and it come at a cost
- This cost can be
- Prevention – covers activities that prevent quality problem from happening. (E.g. testing individual parts at early stages, training)
- Appraisal – covers activities that keep product defects from reaching the client (E.g. Inspection, testing, auditing)
- Failure – covers activities generated if the product fails after it has been delivered to customer(E.g. downtime, rework, troubleshooting)
