Financial metrics are the cornerstone of post-implementation review, providing a clear picture of the economic impact of the project. Return on Investment (ROI) is a primary metric, offering a direct measure of the financial return compared to the project's cost. According to a PwC report, a positive ROI is indicative of a successful project, but it's crucial to consider the timeframe over which this return is realized. Additionally, Net Present Value (NPV) and Internal Rate of Return (IRR) are critical for understanding the project's value over time, taking into account the time value of money. These metrics help in comparing the project's performance against initial forecasts and against alternative investments.

Cost Reduction and Revenue Increase are also vital financial metrics. They provide insights into the efficiency and effectiveness of the project in optimizing operational costs and generating additional revenue streams. For instance, a Deloitte study highlighted how digital transformation projects often aim for cost savings through automation and improved operational efficiency, while simultaneously seeking to unlock new revenue opportunities through innovative business models and services.

Break-even Analysis is another important financial metric, especially for new ventures or product launches. It helps businesses understand how long it will take for the project to recover its initial investment and start generating profit. This metric is particularly useful for startups and companies venturing into new markets or product lines, as highlighted by a Bain & Company analysis on market entry strategies.

Operational metrics focus on the efficiency and effectiveness of business processes post-implementation. Key Performance Indicators (KPIs) such as process cycle times, production costs, and quality rates are essential to evaluate improvements in operational excellence. A McKinsey report on Operational Excellence emphasized the significance of measuring process improvements not just in terms of cost savings but also in quality enhancements and speed to market, which are critical in today's competitive landscape.

Inventory Turnover and Supply Chain Efficiency metrics are particularly relevant for manufacturing and retail sectors. These metrics provide insights into how well the company manages its inventory and supply chain operations, directly impacting customer satisfaction and financial performance. An Accenture study on supply chain resilience underscored the importance of these metrics in assessing the agility and responsiveness of supply chains in adapting to market changes and disruptions.

Employee Productivity and Engagement metrics have gained prominence, especially with the shift towards remote work and digital workplaces. Metrics such as employee satisfaction scores, turnover rates, and productivity measures are crucial for understanding the impact of business cases on the workforce. According to a report by Gallup, companies with high employee engagement report significantly higher productivity, profitability, and customer ratings, underscoring the importance of tracking these metrics post-implementation.

Customer Satisfaction metrics, including Net Promoter Score (NPS), Customer Satisfaction Score (CSAT), and Customer Effort Score (CES), are indispensable in evaluating the impact of business cases on the end customer. These metrics provide direct feedback from customers regarding their experience with the company's products or services. For example, a study by Bain & Company on the value of NPS found that companies with leading NPS scores in their industry outgrew their competitors by a significant margin, highlighting the correlation between customer satisfaction and business growth.

Market Share and Brand Perception are also critical for assessing the strategic impact of a project. Gaining market share post-implementation indicates successful market penetration and competitive advantage, while improvements in brand perception reflect positively on the company's reputation and customer loyalty. These metrics are often analyzed through market research and brand studies conducted by firms like Gartner and Forrester.

Finally, Strategic Alignment metrics ensure that the project outcomes are in line with the company's long-term goals and strategies. This involves evaluating the project's contribution to strategic objectives such as market expansion, digital transformation, sustainability, and innovation. A study by McKinsey on Strategy Development highlighted the importance of aligning project outcomes with strategic priorities to ensure long-term business success and resilience.
