13.5.1 Assessing solution effectiveness

• Success criteria are used to evaluate the effectiveness
• What is one type of factor to consider when defining success criteria?

  Functional requirements
• Performance metrics, such as speed and accuracy, are part of success criteria.
• User needs are a key consideration when defining success criteria
• What is an example of a success criterion for a book inventory management solution?

  Error rate < 1%
• Match the data gathering method with its advantage:

  Observation ↔️ Provides natural usage insights

  Surveys ↔️ Efficient large-scale feedback

  User Testing ↔️ Direct assessment of usability
• What are three methods used to gather data about a solution's performance?

  Observation, surveys, user testing
• Observation provides natural usage insights
• Surveys are efficient for gathering large-scale feedback but lack detail.
• What does user testing directly assess?

  Usability and functionality
• Steps to determine if a solution meets its objectives by analyzing data against success criteria.

  1️⃣ Define success criteria

  2️⃣ Gather performance data

  3️⃣ Compare data with metrics

  4️⃣ Analyze results against criteria

  5️⃣ Determine pass or fail
• A library inventory system with an error rate of 0.5% meets the accuracy criterion of less than 1%.
• Areas for improvement focus on optimizing performance and user satisfaction
• What is the primary goal of improving efficiency in a solution?

  Reduce processing time
• Improving accessibility ensures a solution is usable by people with disabilities.
• What are the key components of a good documentation report for evaluating a solution?

  Overview, methodology, results
• Match the documentation format with its description:

  Narrative Report ↔️ Detailed written report

  Table-Based Summary ↔️ Structured table highlighting key points
• What are three considerations for defining success criteria?

  Functional requirements, performance, user needs
• A library inventory system aims for an error rate of less than 1%
• A transaction time of less than 5 seconds is a performance success criterion for a library inventory system.
• Steps to analyze data against success criteria and determine if a solution meets its objectives.

  1️⃣ Gather performance data

  2️⃣ Compare actual data with target metrics

  3️⃣ Evaluate results against success criteria

  4️⃣ Identify areas for improvement
• In the example, the library inventory system meets all success criteria
• Efficiency in a solution focuses on reducing processing time and resource utilization.
• What does accessibility ensure in a solution?

  Usability for all users
• A good documentation report should include a summary of key findings
• Match the documentation format with its advantage:

  Narrative Report ↔️ Comprehensive explanation

  Table-Based Summary ↔️ Easy to read and quick to reference
