Why Process Mapping?

Process mapping: Visually represents the work process

Identifies problem areas and opportunities for processimprovement

Provides a common understanding of the entire process and

specific roles and contributions of process participants. Before you can improve a process, you must understand it.

Process maps are good for: Streamlining work activities and telling new people, as well as

internal and external customers, "what we do around here."

Helping in the effort to reduce cycle time, avoid rework, eliminatesome inspections or quality control steps, and prevent errors.

Process maps are a great problem solving tool Helps us determine what is the problem/what it is not

What is a Process?

A process converts

inputs into outputs

How to Create a Simple Process

Flow Diagram Determine the start and stop points

to your flow of process steps . Thestop point is typically near thecustomer.

Walk through the flow, writing downthe process steps as they exist now(Rule of thumb: Pretend your are

the part). Make sure you use a verbto describe the process step. You can be very general or very

specific. General: Machine Part

Specific: Turn part, grind outsidediameter, and deburr part

At a minimum, record the processsteps, decision points, andtransportation methods

Once you have roughly mapped outthe process, make it more formal byadding symbols.

Once finished, sign and date theflow diagram with a revision level.

What Can Be Included in a Simple

Process Flow Diagram

Transportation methods

Start and Stop points

Decision points

Inventory/Storage points

How many operators at each process step

Process parameters for each step: Cycletime, throughput time, scrap rate, etc.

Responsibilities for each step

Exercise for Process Map

Take a critical operation in your work place

and map it with a simple process flow

diagram.

A Deployment Flow Chart (Swim

Lane) Here a "department" or "agency"

dimension is added horizontallyalong the top of the chart. Youmay use individuals, groups,departments, functions, etc. -whatever kinds of 'units' playmajor roles in the process.

Draw vertical lines to separate thefunctional boundaries.

When the flow moves from onefunction to another, a horizontalline denotes this.

Draw the sequence of activities

from top to bottom. Use the task and decision-making

symbols as before and alwaysconnect symbols with arrowsindicating the direction of flow.

SIPOC

Suppliers:The entities that provide whatever is worked on in theprocess (information, forms, material). The supplier may be anoutside vendor or another division or a coworker (as an internalsupplier).

Input: The information or material provided by the supplier and used

by the process.. Process:The steps used to convert inputs into outputs. (somesteps are value added and some are not value added)

Output:The product, service or information being sent to thecustomer. This is what the customer pays for. He/she wants output:

With good quality

Delivered on time At a competitive price

Customers:The next step in the process, or the final (external)customers.

How To Create a SIPOC Diagram

1. Create an area that will allow the team topost additions to the SIPOC diagram. Thiscould be:

A transparency (shown with anoverhead projector) made of theSIPOC template

Flip charts with headings (S-I-P-O-C)written on each

Headings written on post-it notesposted to a wall.

2. Begin with the process. Map it in four to fivegeneral steps.

3. Identify the outputs of this process.

4. Identify the customers that will receive theoutputs of this process. You can add a sixth column and list the

customers requirements (CR) such as a

blueprint number, specification number,quality goals, and delivery goals.

5. Identify the inputs required for the processto function properly.

6. Identify the suppliers of the inputs that arerequired by the process.

Other Mapping Techniques

Value Stream Mapping: Every lean event

or initiative should start with a value

stream map (VSM). In addition to showing

the sequence of process steps, the maphelps identify areas of process waste.
