Yes, you do have to point out that something is wrong, and you have to insist that change occurs but it is important to respect the other party’s dignity at all times. The best way to do this is by assuming that the other person is unaware that they have done something to upset you. This allows you to keep the feedback constructive i.e. focused on helping them to improve their performance.
Constructive feedback is easy to use. You just have to remember the what, the why, and the how.
What is the issue?
Why is it an issue?
How do you move forward?
So, now that you know the important aspects of constructive feedback; how do you deliver it?
6 Steps to delivering constructive feedback:
Clarify the issue and the reason it upsets you before you seek to deliver the feedback.
Ask the other person for a moment of their time and ensure that you are in a location where privacy is guaranteed.
Explain the issue and why it upsets you in a clear manner.
Clarify their understanding of the issue.
Inform them that you are not happy for things to continue as they are and ask them to suggest solutions.
Agree on a suitable way forward. Only agree on a way forward if you genuinely believe that it will solve the issue.
Constructive feedback can take time. It is always important to follow-up after you have delivered the feedback. Allow the other person sufficient time to implement the agreed actions. Should they fail to implement the agreed actions, you may choose to reinforce the feedback; implement disciplinary procedures; or, escalate the matter to a higher authority e.g. a more senior manager. The appropriate choice is a matter of context and conscience which must be determined on a case by case basis.
When you learn to deliver constructive feedback, it helps you avoid many of the dangerous pitfalls of communication e.g. passive aggressive behaviour.
Where constructive feedback is implemented it is important that this is recognised. Remember to use positive feedback and praise them when they display the desired behaviour.
