Checksheets are simple tally sheets that are used to gather data. It is part of the seven basic quality tools that are used within the context of the plan-do-check-act cycle in solving quality-related issues within a particular project management plane.

This project management term is also known as tally sheets and is used to gather data and facts to facilitate effective collection of data concerning a potential problem. Checksheets are very effective in gathering data about the attributes of the project. Moreover, it is also used to inspect the project in order to identify different defects that may arise from the project. Data gathered using the checksheets are also used by other basic quality tools for more analysis. For instance, the tally sheets are often used together with the Pareto diagram which is a vertical bar chart used to identify the probability distribution of the data.

Creating a checksheet is important in order to determine the different problems that may arise for a particular project. It is also necessary to use this tool in order organize the collected data so that it can easily be identified by the parameters included in the checksheet.

This term is defined in the 5th edition of the PMBOK.
