Process Flow Template

Shows the flow of a product or service through a process,
including inputs, outputs, and sources of variation.

When and Why to use your

Process Flow Chart Template

Prior to creating a PFMEA
(for Process Failure Modes and Effects Analysis)

use the Process Flow Diagram to identify Sources of Variation,
and desired Deliverables (ideal Functions) for each Process Step.

The desired 'Deliverables' column of the Process Flow Diagram

loosely correlates with the 'Function' column in the PFMEA,
and the 'Control Characteristics' column in the Control Plan

and the 'Sources of Variation' column

loosely correlates with the 'Potential Failure Mode' column of your PFMEA

Can the Process Flow Diagram automatically update the FMEA?

Yes.

If you use the Process Flow Diagram worksheet within the same workbook with your PFMEA,
then the two can share the same dropdown lists,

and you can use Excel's cell linking feature to automatically change one cell when the other changes,
and Excel's concatenate feature auto-populate a single cell with the values from multiple other cells.

However, be aware that auto-populating data is not always a great idea

Take a moment to think about it...

Thimk

What is the core purpose of creating a Process Flow Diagram?

(and other related FMEA documents, like the P-Diagram, Interface Matrix, Boundary Diagram, DVP&R...)

Is your purpose to "quickly and automatically populate a sheaf of documents"?

Or is the core purpose to go through some mental exercises
specifically designed to stimulate human thinking?

so that you don't overlook some (perhaps initially not obvious)
possible failure modes

If you skip the human thinking part —
what was the point of quickly auto-populating all those related documents?

If some failure mode, cause, or effect slips through unnoticed,
then those related documents didn't serve their foundational purpose, did they?

If you're completing all of those related FMEA documents in the ways they were intended...

then there should be only a loose correlation between the related columns in the related documents.

The 'Sources of Variation' column of the Process Flow Diagram
loosely correlates with the 'Potential Failure Mode' column of your PFMEA,
and the desired 'Deliverables' column
loosely correlates with the 'Function' column in the PFMEA,
and the 'Control Characteristics' column in the Control Plan.

The human thoughts recorded in the one document should stimulate related (but not identical) thoughts in the other.

So the answer is yes...

The Process Flow template can share data with your PFMEA,

but hopefully you will honor and appreciate the core purpose
underlying the whole point of doing the exercise of creating a Process Flow Diagram,

and will use those features sparingly and wisely.


How to use your Process Flow Diagram

Before getting started

Dropdown lists for faster data entry and fewer mistakes

Your leaders should have already personalized
the DV sheet in your master template
so that you are starting with typical dropdown lists for YOUR company.

Find and open your template

In the same way that you find and open your other 150+ Systems2win templates, find and open either:

  1. ProcessFlow.xlsx

    for a stand-alone Process Flow Diagram template

  2. FMEA2.xlsx

    newer versions of the FMEA template now give you the option to have Process Flow Diagram worksheets in the same workbook with your PFMEA

Process Flow Chart template

Draw the Flow Chart

Use what you have learned about how to Excel as a drawing tool

to draw the Flow Chart in the first columns.

Once you have learned how to use Excel as a drawing tool,
you know how to use Excel to draw ANY of the many types of flowcharts
that you might encounter along the course of your lean journey.

Process Step number and Description

The short description for each Process Step should start with an action verb,
and answer the question: "What is this step of the process supposed to do?"

With your Systems2win Process Flow Template,
you have the choice of using either:

  1. Large Icons (with the Step number and Description included as text within each shape
  2. Small Icons (with the Description in a column alongside the icons)

    and you even have the option of either using the separate # column to separate the Process Number from the Description, or just hide that column and include the Process Number within the Description

Row Heights

Tip: Use the final column to set row heights

using ALT-ENTER to add or remove numbers in that final column
that is outside of the Print Area

Include all production steps

from processing of individual components to assemblies —
including shipping, receiving, material movement, transportation, storage, labeling, etc.

The PFMEA should be consistent with the scope and information in the process flow diagram.

Identify Sources of Variation for each Process Step

Perform a preliminary risk assessment
to identify which steps can impact the product or service, and should therefore be included in the PFMEA.

Identify desired Deliverables (ideal functions) for each Process Step

Identify the Deliverable requirement outputs that should be achieved for each Process Step.

Deliverables are the outputs of each step and relate to the requirements for the product/service and the processes needed to deliver that product/service.

Desired Deliverables provide the team with a basis to identify Potential Failure Modes in the PFMEA, and although many Desired Deliverables will correlate on a one-to-one basis with a corresponding Potential Failure Mode on the PFMEA and/or a Control Characteristic on the Control Plan, there are many circumstances where there will NOT be a one-to-one correlation. See the discussion in the section above.

In order to assure continuity, the same cross-functional team should develop the Process Flow Diagram, PFMEA, and Control Plan.

Whenever anything changes

Be sure to edit all control documents, including the FMEA and all of its related documents,
Control Plan, Standard Work Instructions, Leader Standard Work, Checklists, etc.

Use the Revision Log worksheet and your company's document storage and naming conventions
to maintain archives and history of revisions over time.
