In this lesson, you will explore outcome evaluation and reflection in software engineering. You will focus on testing solutions for short-term and long-term outcomes and learn how to communicate on design processes through group reflections and presentations.

By the end of this lesson, you will:

1. Understand how to evaluate software solutions for short-term and long-term outcomes.
2. Learn methods for testing and assessing these outcomes.
3. Explore group reflections to discuss project successes and challenges.
4. Discover how to prepare and deliver presentations on design processes.
5. Reflect on a project scenario to apply these concepts.

Short-term outcomes are the immediate results of a software solution, focusing on how well it performs right after development and launch. These outcomes check if the solution meets its basic goals in the short term, such as functionality, usability, and efficiency in everyday use.

Key aspects of short-term outcomes include:

• Immediate functionality: Does the software do what it's supposed to, like saving data correctly or responding to user inputs without errors?
• User satisfaction: Is it easy to use? For example, can users navigate the app intuitively?
• Performance metrics: Things like loading times or response speeds, ensuring the app runs smoothly from the start.

Long-term outcomes refer to the sustained impacts of a software solution over an extended period, often months or years after its launch. These outcomes evaluate how well the solution adapts to changing needs, scales with growth, and maintains value in the long run, such as through ongoing reliability, adaptability, and overall impact on users or organisations.

Key aspects of long-term outcomes include:

• Sustainability: Can the software be maintained easily, with updates to fix issues or add features without major overhauls?
• Scalability: Does it handle increased usage, like more users or data, without performance drops?
• Broader impact: Things like user retention rates or cost savings over time, ensuring the solution remains relevant and beneficial.

Testing solutions involves systematic checks to verify short-term and long-term outcomes. This is not about coding but about planning and executing tests to evaluate effectiveness. Thorough testing ensures your software meets immediate needs and future demands, identifying strengths and improvements early.

Steps for testing:

1. Define criteria: Outline what success looks like. For short-term, list goals like 'app loads in under 3 seconds' or 'error-free registration'. For long-term, include 'handles 10x users in two years' or 'remains secure over five years'. This provides evaluation benchmarks.
2. Choose methods: Select techniques based on outcomes. Use surveys or checklists for short-term usability; simulations for long-term scalability. Track metrics like CPU usage or response times. Ensure methods are practical for your resources.
3. Conduct tests: Run scenarios, such as stress tests for long-term durability or usability tests for short-term satisfaction. Document issues to capture performance fully.
4. Analyse results: Compare data to criteria, identifying patterns like slow loading (short-term flaw) or scalability limits (long-term risk). Use insights to improve code or features and refine design.

This process evaluates solutions against real-world expectations, making software more robust and user-friendly.

Group reflections allow teams to discuss project experiences, focusing on what worked, what didn't, and lessons learned. This fosters communication on design processes, helps refine future work, and builds a collaborative team environment.

How to conduct group reflections:

• Gather the group: Meet in person or online to review the project, ensuring a comfortable setting for open discussion.
• Structure the discussion: Use prompts like 'What design choices led to successful outcomes?' or 'How did we handle challenges in testing?'.
• Encourage input: Ensure everyone shares views on short-term achievements and long-term implications, promoting equal participation.
• Document insights: Note key points for reports or presentations, and consider how these can inform future projects.
