Time Studies

Time Studies

A centralized location for all time study data with a tight link to the process routing, work instructions, and line balance.  Full support for all standard Predetermined Time Systems as well as a Powerful Live and Video-based Observed time study capability.  Tight integration with Lean/MUDA task classification and Ergonomics analysis and Reporting.

Standardize, Control, and Maintain

Time study data is created in a standard format, stored in a single location, and available for review indefinitely. Many organizations waste engineering effort questioning the validity of existing time standards and subsequently recreating the study using any preferred time study spreadsheet.

Integrated Video Studies

Videos can be imported into the application and then segments of the video can be associated to activities. This allows for time standards to be rapidly created and for traceability, as the video reference is available to the entire organization.

Predetermined Motion Time Studies

MTM, MODAPTS, and MOST studies can be performed, by directly entering element codes into a spreadsheet interface or through selecting motions from a template. Codes can be linked to standard waste classifications and ergonomic impacts.

Man-Machine (Gantt) Chart Capabilities

Assign tasks to operators and machines and define the sequence and precedence of tasks to create man-machine charts. Identify idle time and critical path to improve resource utilization.

Waste Analysis

Simplify process improvement efforts by establishing a standard procedure for identifying and categorizing value- and non value-added tasks. Compare before and after results using color-coded waste categories. 

What is wrong with the traditional method of using stop watches on the floor and Excel for creating and maintaining time studies?

  • There is a lack of visibility across the organization to the time study data.

  • Collaboration is difficult when spreadsheets are stored on engineers' computers or in a file share directory. 

  • There is no good way to connect the individual elements or time study data in a spreadsheet to the work instruction or process routings.

  • It is difficult to integrate videos into spreadsheet studies and too easy to have a collection of videos on the file share disconnected from the study data.  

  • Once the time standards have been established, there is a difficult process ahead to update time standards in the ERP system.

  • The teams completing the time studies are often different from the teams responsible for completing lean events and ergonomic studies. This disconnect results in rework and lack of clarity on the standard definition of a task.

Assembly Planner's system for creating and maintaining time studies brings advanced capabilities to the engineer completing the study and to the organization for accessing and updating the data over time.

  • All time study data is created and stored in the same location in a standard format, eliminating issues with lost spreadsheets or rework. 

  • Time study data is easily entered through a spreadsheet interface.

  • Direct link to the work instruction, line balance, ergonomic study, and labor calculations.

  • Predetermined time standards, MTM (MTM-1, MTM-B, MTM-UAS, MTM-MEK), MOST (Basic MOST, MaxiMOST), and MODAPTS standards are supported. Standards can also be customized. 

  • Standard time systems can be used concurrently to help organizations transition between systems.

  • Engineering teams can customize their own templates to reduce data entry time and quickly pre-populate lean and ergonomic studies. 

  • Video-based observed time studies allows for traceability of the data.

  • Classify and color-code time elements based on standard organizational codes and descriptions for value/non-value added analysis.

  • Completed time study can be reviewed and applied to standard time at a later date.



Proplanner provides a single system for engineers to create a plan for manufacturing. We suggest you review these solutions next:


Line balance scenarios can be merged with order details to perform advanced scheduling and operator allocation


New work instructions are generated automatically when new line balances are developed


Parts can be mapped directly from the BOM to tasks in the routing


Parts mapped to tasks can update logistics planning (PFEP)
