What is your experience implementing business entities’ management, or business process management?

Hey there!

Analyze the current situation in the processes, collect all the data and make it readable. For instance, using visualizations (charts, graphs, etc.) Reflect about it all. 2) Implementation. According to conclusions, try to implement new solutions in routine activities. For example, automate work with document approvals, reporting and other common tasks. 3)Testing. Test new processes on small group, to avoid possible problems and find bottlenecks. 4) Execution. Scaling and keeping track of the processes and fixing them depending on the results. From this stage, you have to optimize and add business processes continuously. Have you experienced implementing business entities’ management? It would be interesting to know your tricks and cases
