There has been a noticeable return in the past decade toward process in
improvement work…a focus on improving and managing business processes. It is a
general understanding that the business processes are the work we do. And, if we
want to be better at what we do, we need to look at our processes. Without a
method and good tools, good intent is often squandered. We need to look at our
processes in more than a cursory fashion. We need to look at them in detail and
understand the details. When we don't understand the details, it is easy to miss
inefficiencies. When we don't understand the details, we may be enabling
subversive or counterproductive activity. On the other hand, when our processes
become transparent, it is difficult to not see the problems.
If we want to improve our processes, we need to understand them IN DETAIL - by
reviewing and analyzing detail process charts. Simply talking about processes
won't cut it. Looking at them from 10,000 feet isn't going to cut it -- If we
read through procedures and talk to the managers and supervisors about the
processes, we are gaining an understanding that is at least one step from
reality. If we document processes using this information, the documentation will
not reflect reality. We need two things to make useful detail process charts…the
right information and a good tool.
The right information
The right information is NOT captured on any document. The best you can hope for
in a document is a snapshot of a point in time. The longer the documentation
sits around, the greater the likelihood that it has become outdated. Processes
change and the documentation that supports them (if any exists) necessarily lags
behind. Even detail process charts become dated the longer they sit.
The right information is NOT in the heads of the managers and supervisors.
Managers and supervisors should be managing and supervising. They should not be
getting involved in the details of the work they are managing. The right
information IS in the heads of the PEOPLE WHO DO THE WORK - the people who, day
in and day out, are living the process that you want to document. It is the
accumulated experience specific to the process that you want to chart. These
people know WHAT HAPPENS in their part of the process better than anyone else
because it is what they do. They know what appears to make sense in the process
and what appears to be nonsense in the process. They know how to make their
piece of the process work and how to get around it when it doesn't work.
Even with the right people, it is not enough to just ask them what they do. If
you want your charts to reflect reality, then watch reality. Observe the
process. See the person in action. It simply makes good sense to collect the
process information - gather the facts - at the workplace. There are many
reasons why it makes sense to gather the facts at the workplace. You can see how
the work starts and how it is finished. If you observe the work being done, the
information sources and reports become apparent. You have access to forms,
source documents, logs and system applications that are involved in the process.
(It's a good idea to collect copies along the way. They will be helpful during
analysis and may be useful when you are preparing the process chart.) You can
observe the physical layout and see if the process causes the person to leave
the workspace for any reason (to pick up or drop off work, make copies, pick up
printouts, gather source information…). If you try to document the process with
a group of the right folks gathered together in a room, you will miss things.
The focus will be on the "value-added" steps (filling in the forms). While this
information may be correct, you will likely overlook the non-value-added steps
that account for the majority of the processing time.
The right tool
The right tool must provide useful information that helps people do their jobs
better. It should be easy to use and easy to understand. There are a lot of
tools available that provide symbol sets. But if the symbols are not wrapped in
a methodology, then the charter has to invent one. (Collecting the data,
stringing the symbols together, handling rework…unusual situations…)
Fortunately, the work simplification charting method has made this easy with a
small, well thought out symbol set and methodology that provides elegant
structure to the ominous task of process charting. The fact that the work
simplification symbol set was adopted as the ANSI and ASME standards for Process
Charting fifty years ago is testimony to its fundamental simplicity. It has
flowed through a half century of new technologies and constantly changing
processes with the grace of an alphabet…because it is fundamental. It is basic.
It gets to the roots of our processes. It speaks the language of process.
 Four
basic symbols represent doing work, checking work, moving work from one location
to another and nothing happening.
Four additional symbols represent variations of doing work. The four variations
of doing work include three variations of value-added work and a symbol
representing destruction or termination. The value-added symbols are the Do
symbol for manufacturing processes and the Originate and Add/Alter symbols for
information processes. That's it! Eight symbols.
It is just as easy to document the drafting of a letter whether it is
handwritten or prepared electronically - the letter is CREATED.

It is just as easy to document the transport of the letter if it is hand
carried, delivered by a postal carrier or sent electronically - it is MOVED from
one location to another.
The beauty lies in its genuine problem-solving format. It breaks down the work
to INDIVIDUAL elements. The processing of each item (document, form, letter,
log, record, file, email…) is represented as a horizontal line. The name of the
item is identified in a label at the beginning of the line and the activities
(AND periods of non-activity) that occur are represented with symbols laid along
the line in sequence.

Most information processes include the processing of several items. Any
relationship between two items, where the information on one item causes
something to happen to another item is clearly represented. (The receipt of an
item is entered on a log, an order form is transcribed into the Order System,
the receipt of an item causes a project file to be pulled, a photocopy is made,
an electronic document is printed, an account number is checked against a bad
account list…) The relationship is displayed with vee-shape line that points
from the item providing the information (the open end of the vee) into a symbol
that represents the activity that happens to the other item.

These relationships between items
are what tie many items together as a single process. This is arguably the most
difficult concept to grasp for a person preparing multi-flow process charts.
However, with little explanation, most people can read and understand a properly
prepared chart.
With a single line process flowchart, what happens when the work divides? At
best, the multiple items are described in the activity. With a multi-flow chart,
when the work divides or separates, the chart separates. What was a single flow
line becomes multiple flow lines.

This takes us back to our fundamental concept of breaking the work down into
individual elements.
Even at a bird's-eye view, the number of items in this simple process stands
out.

Delays are apparent. Movement between work areas is apparent. Value-added work
is apparent. The amount of non-value-added work is apparent.
Most business processes that are mapped are mapped at a high level with
single-line process maps. This type of mapping is derived from the programming
flowcharting technique that was introduced by IBM in the late 60s. It is a
useful tool for following the flow of a program. The flow is the program. The
focus is on the program. Processing is shown in a Process rectangle and
Alternatives are presented with a decision diamond. Inputs can be identified as
parallelograms with a line into the program line and outputs are identified as
parallelograms with a line coming out of the program line.
Applying this method to business processes is difficult. People don't normally
think in terms of inputs and outputs. They understand the work they do -
documents, forms, application screens… The method is not intended to follow
multiple flows. The single flow is a program. Business processes rarely involve
only a single item. They may include multiple documents and involve interfaces
with several programs. Adapting the documentation of business process flow to
the structure of program flowcharting necessitates grouping blocks of work into
process or activity boxes. Individual items get buried in the activity boxes or
overlooked. The concept of value-added is not employed. Delays are typically not
identified. Every single step invites assumption.

Still, good people who understand parts of the process can get some value using
high-level charts for improvement. Some modify the method to incorporate genuine
detail process symbols (or steps) to denote delay, transportation… This is a
testimony to capable people who manage to be successful despite having
inadequate or inferior tools. High-level charts may provide enough structure to
help an analysis team stay focused on the process and challenge the process
blocks in sequence. HOWEVER, the team will have to dig into details to make good
decisions about the process.
Since the value of high-level charting is limited, it is often given cursory
attention or is even ignored reinforcing a self-fulfilling prophecy - process
charts don't provide much value, therefore we won't use them (thereby ensuring
that there will be no value provided!). WE SHOULD NOT BE USING HIGH-LEVEL CHARTS
FOR IMPROVEMENT! We should use detail charts and capitalize on the true value of
process charting. The process represented in the previously displayed high-level
chart was also captured in a detail process. The detail chart stretched over
fifteen feet long. While daunting from a distance, when you focus in on the
steps, each step is clear. As you move from one step to the next, each step
makes sense, the workflow becomes clearer and the process becomes
understandable.
Detail charts may be intimidating at first glance. However, the chart is a
reflection of the process. If the chart is complicated, the process is
complicated. It is a challenge to understand a complicated detail process chart
that flows through several workstations, passes through departmental boundaries,
causes the origination and dissemination of dozens of forms, logs and reports,
requires access and manipulation of data in multiple systems by many users.
Imagine a team of people trying to sort out and make decisions about the details
of a process with several hundred or even thousands of steps without the benefit
of a detail chart.
We wouldn't consider building an automobile, an aircraft, a home, an office
building… without the benefit of a blueprint. Business processes, on the other
hand, are often built on the fly, then parts of the process are modified in
isolation. In a short time, a process can evolve into a convoluted, inflated
mess that nobody understands completely.
An experienced charter can often produce a detail chart more quickly than a
high-level chart simply because there is a structured methodology to support it
(the charter doesn't have to figure out what to include and exclude from each
step).
Many improvement methodologies state the importance of identifying the current
process, yet don't specify how to do it. It would be to the advantage of anyone
promoting an improvement methodology (or certification requirements) to offer
guidelines that will help people accomplish this essential first step
successfully.
Tools for building and maintaining good business processes have been around for
a long time. Chances are there are people in your organization that have worked
with or at least seen detail process charts some time in their career.
While there are organizations benefiting from the use of detail process charts
around the globe, there are many more that are not. We need to instill into our
organizations a discipline to become masters of our processes and not slaves to
them. Building and maintaining a library of detail process charts is the first
step.
