These are the outlines, directions, or procedures to be followed in order to complete a task.

There are four steps to follow to complete a task in a professional manner.

1. Define the work.

Before starting to work, make a list point by point about the work to be done, and ask your client or boss to confirm it in order to double check and go on insurance.  If you have doubts, always ask.  

2. Create a work schedule.

Creating a work calendar is not only useful to define and fix what is going to be done each day and how much time is allocated to each task until completing the project, but also allows to foresee possible delays and adjust the dates so that there are no problems with the deadlines.  

3. Work in stages.

Any project, no matter what its size, should be divided into small stages, sub-tasks or milestones for the client or your boss to approve each step and you can continue to move forward based on your feedback.  

4. Communicate with the client or your boss permanently.

Communication with the client or your boss should be an obligation throughout the entire project. Although the delivery dates are clear, the tasks to be developed are defined and the stages to deliver results are fixed, you always have to keep communicating with the client or boss and keep up to date with your progress even if the work is done. This generates security and confidence, and it is also likely that they will be more understanding of any mismatch if communication has always been efficient and fluid.  

Having a well-defined work methodology is essential to work with productivity.
