| This step of the PDCA cycle aims to determine real success of your  improvement project in terms of the tools and processes you used during the Do  step. It focuses you on reviewing the project and its progress to determine  whether the work is performed according to the plan and whether expected  results are obtained. You will measure performance of your project and  procedures against desired changes. If any deviation (actual value differs from  the target value) appears you will need to search for the cause of that  deviation and develop a solution that addresses the problem. As a process, the  Check step of the PDCA cycle can be performed in these two major activities: 
          Problem  diagnosisSolution  implementation Generally speaking, these activities entail conducting problem-solution  analysis that aims to determine why improvements to a given project are not  implemented and then to design a set of scenarios that address the problem.  Below in this article we will talk about both activities of the Check step and  explain how to manage the activities and conduct the analysis. At the end of  the article we present a checklist of tasks to manage the step. Problem DiagnosisThis activity starts with reviewing measures created at the Plan step to  determine actual improvements made by your project against goals or  expectations. These measures help you understand whether the project implements  the planned solution to make necessary changes to the working environment.
 If the measures show that in your project there is a deviation from the  baseline, you need to create Issue Log to record all the deviations detected.  Then you use Issue Log to determine what tools and processes relate to every  deviation detected. In such a way you will identify reasons for problems and  determine why improvements are not made by the project. In general, you  must do the following tasks to diagnose problems: 
          Use  the measures set to determine actual improvements against preset expectations.Detect  and record deviations.Create  Issue Log that keeps all the records on deviations.Review  Issue Log to diagnose real problems.Determine  what tools and processes cause problems.Develop  a report that summarizes the stage. When all these tasks are done, you must review the problem diagnosis report  to get a list of detected problems. By using Problem Evaluation Matrix (PEM)  you can rank all the problems by significance in order to determine which  problems to solve first. PEM is a flat table that ranks identified problems by  significance and score to calculate weighted score per problem. Below you can  see an example of PEM. 
          
            | Problems Identified
 | Significance, % | Score | Weighted Score/100% |  
            | 
              Lack of financial resources | 10 | 12 | 1.2 |  
            | 
              Reduced employee productivity | 6 | 8 | 0.48 |  
            |  | 3 | 4 | 0.12 |  
            |  | 15 | 20 | 3.0 |  
            |  | … | … | … |  
            | Total:  | 100% | --- | X |  Each problem gains Weighted Score that determines how significantly the  problem influences your working environment. You must weight all problems to  focus on the most significant ones. Solution ImplementationThe second activity of the Check step requires you to review the most  significant problems and then try to develop appropriate solutions. If you  can’t develop a solution to a problem, you must loop back to the previous step  for further diagnosis and investigation.
 We suggest a 3-step  process for implementing solutions to problems. This process includes the  following steps: 
          Identify the most effective way of implementation. You need to determine possible  ways of implementation while considering each selected problem and configuration  requirements. Through analyzing these ways you will identify the most  appropriate solution to each problem. It means you will get the best  implementation way that entails the lowest cost, minimized time duration, and  minimized number of iterations. When the most effective  way of solution implementation for every problem is determined, you need to  develop a list of actions or activities required to follow this way. Also you  need to define relationships between those activities. Prioritization can be  used to solve this issue. Priorities should be set for every activity, so that  the entire sequence of activities will be defined. Along with priorities,  timeframes and boundaries should be set. You will need to estimate duration per  activity and then determine activity boundaries.  When the previous steps  are done, you can design a flow chart that represents all solutions to problems  in a single diagram. You can use the input data (activity list, priorities,  durations and boundaries) to start drawing squares and triangles and arrows  between them. In such a way you will design a flow chart that illustrates solution  implementation stages. When all the steps are  completed, you must get a detailed pathway to problem solving. Your project  will gain improvements that increase the probability of success. Using Tasks in VIP Task ManagerBelow you can see a  checklist of tasks that can be created in VIP Task Manager. This checklist  explains what tasks to do to diagnose problems and implement solutions. You can  use VIP Task Manager to design the checklist and manage tasks.
