3.3.1. Performance Gap Analysis

Performance Gap Analysis: Compare predicted vs. actual performance, identify causes of discrepancies, and implement corrective actions.

Performance Gap Analysis involves looking at what was expected from a project in terms of performance and comparing it with what actually occurred. This means identifying any differences between these two aspects. For example, if a building is expected to use a certain amount of energy, but it is using much more, this is a performance gap. The next step is to find out why this gap exists. This can include looking at factors like materials used, construction methods, or even occupant behavior. Finally, corrective actions need to be established to close this gap and improve future performance.

Think of it like preparing for an exam. You might predict that you'll score 90% based on your studies, but when the results come out, you only score 70%. You then need to analyze where you went wrong—was it a lack of understanding of certain topics, or did you mismanage your study time? Once you identify these gaps, you can change your study techniques to improve your scores in the future.

Identify causes of discrepancies, and implement corrective actions.

After determining that there is a performance gap, the next crucial step is to identify the causes behind it. Causes can often be related to unexpected variables that weren't foreseen during the planning phase. This could involve analyzing the components used in the construction, unexpected operational circumstances, or flaws in the construction process itself. Once these causes are identified, the project team can formulate specific corrective actions to address these issues and enhance performance moving forward.

Imagine a team of chefs preparing a large meal. They initially planned to serve a perfect dish, but it turned out bland. Upon tasting it and evaluating their whole cooking process, they realize they forgot to add salt. This mistake is the discrepancy. They then decide to adjust their recipe for the next meal by ensuring they follow their checklist and perhaps even doing some taste tests along the way. In this way, they improve future meals through identifying past mistakes.

Implement corrective actions.

With the causes of discrepancies in mind, the next step is to implement corrective actions. This means taking specific measures that aim to resolve the identified issues causing the performance gap. Actions could include re-evaluating design choices, changing operational practices to be more energy-efficient, or better training for building occupants. The goal is to ensure that future performance aligns more closely with the original predictions.

Think of a sports team that loses a game because they didn’t practice enough. After analyzing the loss, the coach decides to implement a new training schedule that focuses more on teamwork drills. This change is the corrective action aimed at improving their performance in future games. Just like the coach, project teams need to review and adjust their strategies to succeed.

Collect and analyze input from end-users on comfort, health, and building functionality to inform future projects.

The last step in Performance Gap Analysis is about looking ahead and making better decisions based on past experiences. Collecting feedback from the occupants of the building provides valuable insights into how well the building performs in real-life conditions. This feedback can help improve future designs and project executions to minimize gap occurrences. Continuous improvement involves integrating this feedback into the planning and execution of future projects, ensuring that they become more sustainable and efficient over time.

Consider a smartphone company that releases a new model. After customers use it, they provide feedback about issues like battery life and camera quality. The company then takes this feedback and uses it to enhance their next model. They might improve battery technology or enhance camera features. This practice of using customer feedback to improve future products is similar to how performance input from end-users informs better construction practices.
