Developing your habit of accountability produces successful results. Assigning a “due” time/date to a project; proposal; meeting; review; appointment, guarantees completion and confidence. When something needs to get done and you surround it with accountable results producing success tips and actions, you have high value, on time, outcomes…every time.
Make sure everyone knows the details of the result you want. That may seem obvious however, miscommunication has produced more bad results than you could ever calculate.
If you are the boss, people might not ask questions because they do not want to appear ignorant. Cover all the bases and make sure the way to success is clear.
Have deadlines; post them; discuss them and then enforce them.
Asking for preliminary results or work before the due date gives everyone a chance to review the work (and comment on the accuracy) before the deadline - you create a space to be accurate and on time.
Make sure the people (or person) understands you want to support them with the work. Ask them what they need and then deliver that support in a timely way.
Check in on projects and people often. They will appreciate it and you will be clear on what exactly is being developed/created. Surprises are usually not fun except at birthday parties.
Congratulate when you get what you asked for in a timely way and in a form that is clear, results producing and high value. A compliment is like a powerful glue – it sticks with people for a long time and feels good all around.
