Say no to no project manager.
Updated: Aug 12, 2019
You wouldn't get on a plane without a pilot nor a ship without a captain ....so don't chance your software implementation without a competent project manager.
Your project manager sets the course, navigates the hazards and fixes the problems. They will work with you to understand your goals, objectives and what destination you want to take your ship. They organise the crew and lead them to understand their purpose and responsibilities. They manage time, who needs to be where and when and who needs to be working with who.
They know the hazards in the implementation sea and know how to navigate freak waves, submerged reefs and marauding pirates.
Don't implement business software in your organisation without having a captain.
