
 To Identify a fair measurement of time needed to
perform a process .
 To Identify the associated time for each of the
process elements .
 To identify the fluctuation in cycle time due to
abnormal conditions or problems occurring during
the process .
The purpose of
time measurement

 Instabilities and variations of processes due to fluctuations in
Cycle Times.
 Deviations from the Standardized Work.
 Inadequate tools.
 lack of training.
 Equipment failure/breakdown.
Reasons for time
measurement

 Time measurement is the determination of the
actual time required to perform a process
 Time Study is the concrete observation,
documentation and description of operation
elements and the associated time for each element.
 Takt Time = Total working days/ Customer demand
Time Measurements
Definitions

Takt Time

 Value refers to what the customer is ready to pay for
this service .
 Value Add: any activity or function of the process or
service increases the market form (The customer will
pay for it).
 Non Value Add: any activity or function isn’t
necessary to the market (The customer won’t pay
for).
What Is The Value?

 Motion outside of the ergonomic zones.
 Each time an operator moves from one workstation to an
other one.
 Visual inspection for compliance and auto-inspection.
 Reading instructions or filling out administrative documents.
 Tasks associated with work organization (change over time,
workstation cleaning, maintenance, etc.).
 Re-packing and labeling of parts required by the process.
 Quality actions (sorting parts, treating rejects, repairs, etc.).
 Operator waiting time.
