Context: Without a customizable checklist for ensuring performance efficiency, enterprises may struggle to meet workload demands effectively. This can lead to suboptimal resource utilization, increased operational costs, and potential delays in project delivery. The lack of standardized performance metrics can result in inconsistent outcomes and reduced overall productivity. Ultimately, the absence of such a checklist can hinder the organization's ability to maintain high performance standards and achieve business goals.

Solution: The customizable Performance Efficiency checklist, adopted from Well-Architected Framework, presents a set of recommendations to design workload so it can grow and meet workload usage demand. The goal of performance is to maintain the efficiency of every interaction with a healthy system as demand increases. When we design and implement for performance, we focus on the efficiency and effectiveness of cost, complexity, supporting new requirements, technical debt, reporting, and toil. 

Impact: For every system, there's a limit to how much we can scale it without redesigning, introducing a workaround, or incorporating human involvement. However, if we don't include performance efficiency practices and consider the tradeoffs, our design is potentially at risk. This Checklist helps carefully consider all the points to instill confidence in system's successful performance.
