We should work as one team, without judgement. We should work hard and collaborate with the team members to meet the end goal!
Yes, it sounds good and philosophical!
However, not all members of your team are competent. The common assumption is that all resources are competent to deliver the outcome per the project estimates. But, within every project, some resources do not carry their weight. So, others have to work more to normalise.
Your project is not an exception. You are dealing with the same challenge!
The question is, do you know what is the cost of incompetence?
