Interrelations among SMED Stages: A Causal Model

Table 1

SMED activities at its conceptual stages.

SMED stages	Activity	Description
Identification Stage	S0 02	Is a statistical analysis performed to know time variability of the process?
	S0 03	Is there a statistical analysis to know the average process?
	S0 04	Is there a detailed analysis of the possible causes of time variability in the process?
	S0 05	Have operators been interviewed about processes and the machines they operate?
	S0 06	Are operators’ activities being measured with a chronometer?
Separation Stage	S1 01	List the main sequential setup operations to identify internal activities.
	S1 02	Detect basic problems that are part of the work routine.
	S1 03	Is the exchange of tools, parts, and supplies performed with the machine on?
Transformation Stage	S2 01	Is the previous work completed before starting the changeover?
	S2 02	Are visual marks used instead of making trial and error adjustments to calibrations?
	S2 03	Have steps for searching tools, raw materials, and products been eliminated?
	S2 04	Have activities been reexamined to make sure none of them was wrongly assumed to be internal?
Improvement Stage	S3 01	Have key setup activities been recorded to improve process time?
	S3 02	Have operators been trained to maintain improvement in processes?
