Definition of a processDefinition of a process
A process is a collection of activities that takes one or more kinds of inputs and creates output that is of value to the customer

Definition of a customer and supplierDefinition of a customer and supplier
A customer is the person /organization/ department that receive AND values the output of a process
A supplier is the person /organization/ department who creates/supplies the process inputs
A customer is the person /organization/ department that receive AND values the output of a process
A supplier is the person /organization/ department who creates/supplies the process inputs

SIPOC – steps that start the processSIPOC – steps that start the processs This is a team decision. s The start of a process is never fixed. example – when
does the process of buying a car start?
1. When your car breaks down2. When you see an advertisement3. When you enter a show room4. When your existing rental ends5. When you talk to the salesperson6. When you can afford one….

SIPOC – key intermediary steps SIPOC – key intermediary steps
s Do not be tempted to record every single alternative route that the process has ever taken.
s Steps should be combined if a process branchess Steps should be combined to reduce the total number
until you have between 5-7 stepsExample
1) Receive castings 1a) Proof machine casting
2) Inspect2a) If poor create NCR and rework
2b) If rework fails scrap
3) Place in Stores4) Heavy cut5) Final cut
could be reduced to 1) Receive castings 2) Machine castings

SIPOC – key inputs and outputsSIPOC – key inputs and outputs
An input or output is an object / decision / piece of information
Key outputs are what the customer(s) value most
Key inputs are those without which the process cannot operate

SIPOC – how to createSIPOC – how to create
1. Draw SIPOC table on flip chart2. Write at the bottom of the output column your primary metric3. Write at the bottom of the process column the name of the step
that ends the process4. Write at the top of the process column the name of the step that
starts the process5. In between, write down the name of 3-5 key intermediary steps in
the process column. Space them equally between the top and bottom
6. Start at the top of the table 7. For each process step write the key outputs, key inputs, key
suppliers and key customers in the corresponding columns at the same height as the process step name
