A variety of problems may be caused by only a few root causes. You might want to dig deeper and find those root causes for the problems. Such root causes are often systematic, i.e. related to your companiescompany's culture and structure, management style, maybe even values and principles.
You can investigate a couple of problems to see if there are common causes (Inin my experience there often is,are; the challenge is to find them and address them).
If you are able to work on the root causes, then there will be less problems in the future. One way to find the root causes is to do a five-times-why exercise in your retrospective. Other ways are to use Appreciative Inquiry or to self assess your way of working.
