Not many, but the few that exist can be significant at times.
1. Company is definitely always moving in the right direction but change can take quite a bit of time. This can be especially frustrating (sometimes even time wasting and impacts ability to work effectively). This definitely tests your patience, but nonetheless change does happen, but the right changes can take quite some time to occur, so remaining positive and remembering to voice impacting issues and feedback is imperative, especially since it's very important to lose sight of how important that is when issues take such a long time to change/rectify.
2. LOTS of time spent/wasted discussing how something, such as a project should be completed, details of scope, frustrations and changes etc. Many times more time is wasted talking about how something should or needs to be completed than actual time spent working on it/developing it. Sometimes even causing massive scope issues and/or projects slipping frequently due to development team being stuck/unable to work on the tasks because of how much time they are spent tied up in meetings ABOUT the item at hand.
3. Promotion of failure, lack of proper metrics for failure or success causing both stagnation, and bloating of employees that should no longer be with company or in specific role.
- since there is nowhere near normal turnover, it is common to see people that have been with the company a long while that either are in a unsuitable role, "burnt out", or flat out don't belong. Instead of working these people out of the company and bring in new fresh talent, it's common for them to be promoted/passed around like a hot potato instead of ever being dealt with on a performance improvement plan or equivalent measures, etc. this is frustrating as it impacts not only the company but very much so the individuals who work with, and share departments with such individuals. This doesn't just impact the manager, it impacts the entire team, causes churn between members and departments, and is a drain on company.
-Common, especially for new roles to take a very long time to establish any sort of metrics/path to promotion or failure. This causes stagnation and the lack or ability to understand where you stand, or the ability to deal with people that should not be in those roles as there are no metrics to easily show success or failure. This can cause a LOT of frustration between individuals, sometimes with others on their same team and many times towards their management team. Understandably, most people don't enjoy being stagnant. If they do, they are probably a hot potato...
-Lack of defined roles combined with such a relaxed environment can lead to severe productivity loss and "screwing around".
