Open-door policies implies that leaders encourage practitioners to come into their office at any time to discuss any issues or concerns. This can be effective, as the leader will be seen as accessible and an open flow of communication will be encouraged.
You will also be more aware of day-to-day problems and able to resolve minor issues before they escalate. Nonetheless, an open-door policy must be well defined, otherwise you may spend a lot of your time listening to concerns without people reaching solutions autonomously.
Without boundaries and guidelines, you may also unwittingly develop a culture of dependency, where practitioners are reluctant to solve problems themselves. Alternatively, they may be reluctant to bother you with their problems, especially if they think you are busy.
The steps provided below should help you reap the benefits of open communication while minimising the disadvantages:
(a) How would they express the problem in a few sentences?
(b) Does it affect only them, or others too?
(c) Can they think of two or three options that might solve the problem?
