Poikkeamienanalyysiä

Poikkeamienanalyysiä, or deviation analysis, is a process used to identify and understand differences between expected or planned outcomes and actual results. It is a fundamental tool in quality management, project management, and business operations. The core idea is to pinpoint why something did not go as anticipated, whether it be a positive or negative deviation.

The process typically begins with establishing a baseline or a set of expected parameters. This could be a budget, a project timeline, a quality standard, or a performance target. Once the actual results are available, they are compared against this baseline. Significant differences, or deviations, are then flagged for further investigation.

The analysis phase involves determining the root cause of the deviation. This might involve collecting more data, interviewing relevant personnel, or using statistical methods. Understanding the cause is crucial for taking appropriate corrective or preventive actions. For instance, if project costs exceed the budget, the analysis might reveal issues with vendor pricing, labor hours, or unforeseen scope changes.

Once the root cause is identified, steps are taken to address the issue. If the deviation is negative, corrective actions aim to bring the performance back in line with expectations or to prevent similar issues in the future. Positive deviations might also warrant analysis to understand what worked well and if those successful elements can be replicated. Ultimately, poikkeamienanalyysiä helps organizations learn from their experiences, improve processes, and achieve better outcomes.
