Study Notes
Software Metrics Overview
- Software metrics encompasses a variety of measurements aimed at improving software processes and projects.
- Measures offer quantitative assessments of attributes related to software products and processes.
- Metrics facilitate tasks like estimation, quality control, productivity assessment, and project management.
- Indicators, formed from metrics, help provide insights for adjustments in processes and products.
Process and Project Indicators
- Process Indicators: Offer insights into how well an existing software process is performing.
-
Project Indicators: Assist project managers by:
- Assessing ongoing project statuses.
- Identifying potential risks.
- Highlighting problem areas before escalation.
- Adjusting workflows and tasks accordingly.
- Evaluating quality control capabilities within the project team.
Classification of Software Metrics
- Metrics are influenced by three factors within a process triangle:
- Skill and motivation of team members.
- Product complexity.
- Software engineering technologies used.
- Metrics are also affected by environmental conditions, such as development tools, business constraints, and customer characteristics.
Types of Metrics
Process Metrics
- Measure the quality and efficiency of software processes.
- Examples include:
- Effort required during development.
- Time taken to produce software.
- Effectiveness of defect remediation.
- Number of defects found in testing.
- Process maturity.
Product Metrics
- Measure software attributes like size, complexity, quality, and reliability.
Project Metrics
- Used to monitor project progress, leveraging historical data for estimates on time and cost.
- Helps in minimizing development costs, time, and risks while improving project quality.
- Metrics guide project managers in adjusting workflows and assessing product quality regularly.
- Examples of project metrics:
- Inputs: Resources required to complete tasks.
- Outputs: Deliverables produced during the process.
- Results: Effectiveness of the deliverables.
- Direct measures include cost and effort; indirect measures assess aspects like functionality and maintainability.
Size-Oriented Metrics
- Normalized metrics considering the size of the software produced, although not universally accepted as the best evaluation method.
- Historical data examples include LOC, defects found, and personnel effort.
Function-Oriented Metrics
- Encompasses measures based on the functionality delivered, originally proposed by Albrecht using function points.
- Function points are computed based on direct measures of the information domain, including:
- User inputs and outputs.
- User inquiries.
- Logical master files.
- External interfaces.
Software Quality Measures
- Correctness: Measured by defects per KLOC regarding requirement conformity.
- Maintainability: Assessed through MTTC, evaluating how easily software can be corrected or adapted.
- Integrity: Ability to withstand security threats, quantifying security measures.
- Usability: Evaluated through user-friendliness based on learning time, efficiency, productivity gains, and subjective user attitudes.
