Measuring BI project success requires collecting and analyzing data that corresponds to your success metrics. This could involve various sources, methods, and tools, depending on the nature and complexity of the project. For example, business value data can be collected from financial, operational, and customer systems, such as accounting, CRM, or ERP. Additionally, BI tools like dashboards, reports, or analytics can be used to analyze this data and compare it with predefined targets. User satisfaction data can be collected from end users through surveys, interviews, focus groups, or observation. Furthermore, BI tools such as feedback forms, ratings, or usage statistics can be used to analyze this data and identify the strengths and weaknesses of the BI solution. Data quality data can be collected from data sources such as databases, files, or APIs. Additionally, BI tools like data profiling, data cleansing or data validation can be used to analyze this data and detect and resolve any issues. Lastly, project management data can be collected from the project team, sponsors and stakeholders through regular meetings or communication. Moreover, BI tools like project management software, risk management software or quality management software can be used to analyze this data and monitor and control the project performance.
