L8: Project Quality & Procurement Management
Project Quality
Quality it defined by:
●How close the project processes and product it to the written specifications
●Can the product be used for what it is intended for
Project Quality Management
Ensures that the project will satisfy the needs for which it was undertaken.
Happens during:
●Planning
●Executing
●Monitoring & Controlling
Processes:
1. Planning: identifying which quality standards are relevant to the project and how to satisfy
them
2. Performing quality assurance: periodically evaluating overall project performance to ensure
the project will satisfy the relevant quality standards
3. Performing quality control: Monitoring specific project results to ensure that they comply
with the relevant quality standards
Planning Quality
Ability to anticipate situations and prepare actions to get the desired outcome.
Prevent defects by:
●Select proper materials
●Training and teach people in quality
●Planning a process that ensure the appropriate outcome
Design of experiments
Helps identify which variables have the most influence on the overall outcome of a process
Scope Aspects of IT Projects
●Functionality: degree to which a system performs its intended function
●Features: System’s special characteristics that appeal to users
●System outputs: screens and reports the system generates
●Performance: how well a product/service performs the customer’s intended use
●Reliability: ability of a product/service to perform as expected in normal conditions
●Maintainability: the ease of performing maintenance on a product
Performing quality assurance
●All the activities related to satisfying the relevant quality standards for a project.
●Goal: continuous improvement (Kaizen)
●Lean: evaluating processes to maximize customer value while minimizing waste
●Benchmarking: generates ideas for quality improvements by comparing other project
practices/product characteristics
●Quality Audit: structured review of specific quality management activities that help to
improve performance for future projects
Modern Quality Management
●Requires customer satisfaction
●Prefers prevention to inspection
●Recognizes management responsibility for quality
Improving IT Project Quality
Establish leadership that promote quality
Understand the cost of quality
●Cost of conformance + cost of nonconformance
●Conformance: delivering products that meet requirements and fitness for use
●Cost of nonconformance: taking responsibility for failure or not meeting quality
expectations
●Cost categories related to quality
○Prevention cost : cost of planning and executing a project so it is error free or within
an acceptable error range
○Appraisal cost: cost of evaluation processes and their outputs to ensure quality
○Internal failure cost: cost incurred to correct an identified defect before the
customer receives the product
○External failure cost: cost that relates to all errors not detected and correct before
delivery to the customer
○Measurement and test equipment costs: capital cost of equipment used to perform
prevention and appraisal activities
Focus on organizational influences and workplace factors that affect quality
Key factors to improving programmer productivity
●Dedicated workspace
●Quiet work environment
Follow maturity models
●Frameworks for helping organisations improve their processes and systems
Controlling Quality
Outputs:
●Acceptance decisions
