What is a Check Sheet?

A check sheet is a quality tool commonly used in the manufacturing industry to identify defects by type, location, or cause and analyze recorded data for improving the production process. As a data collection tool, check sheets enable frontline workers to capture and compile data in a consistent manner, interpret results as soon as they are collected, and observe trends from accurate data collected over time.

Quality control inspectors should take advantage of mobile-ready check sheets to easily classify product defects, identify the cause of quality issues, and implement effective manufacturing process improvements.

When to Use a Check Sheet

Check sheets provide a structure for uniform quality control data collection and a basis for substantiating or refuting quality issues. A check sheet should be used when data can be observed and collected repeatedly by the same person or at the same location, such as a quality control inspector taking note of product packaging defects daily. When collecting data from a production process or about patterns of events, check sheets prove to be the easiest to use while still being effective.

Elements of a Good Check Sheet

Check sheets should be designed in such a way that it establishes a baseline from which improvement can be considered. To achieve desired outcomes, quality control inspectors should be empowered to create check sheets that encompass these elements:


Quality control inspectors should determine how they will classify product defects—by type, location, or cause to accurately indicate how often a specific defect occurred. To validate the effectiveness of a newly made check sheet, conduct a pilot run and apply any necessary changes based on its results. Customizing check sheets with an easy-to-use application can help quality control inspectors save time, which contributes to the overall outcome.


Maintaining the quality of tons of newly-manufactured products can be time-consuming, and quality control inspectors unneededly expose themselves to the risk of losing paper-based check sheets. Transforming check sheets into a mobile app enables data collectors to capture photo evidence of product defects, gather digital signatures of persons responsible, and securely save all data in the cloud.

Instant Reporting

As the starting point for manufacturing process quality improvement, completed quality control check sheets should be immediately reported to the supervisor. Delayed communication of recorded data inevitably slows down continuous improvement efforts, potentially resulting in recurrence of quality issues. With iAuditor, quality control inspectors can automatically generate and share check sheets to members of the organization. Preview sample report.

Real-time Data

Manufacturers can implement effective manufacturing process improvements when they gain visibility of their daily operations. When data collectors complete a check sheet using iAuditor, quality control supervisors can access all recorded data in real-time with iAuditor Analytics. With the click of a button, instantly see the most recurrent type of defect, when and what time the most number of defects occurred, where the check sheet was used, and who used it.
