Why Is Time So Critical? Waste and Opportunity
Thomas Hout and George Stalk, Jr., of the
Boston Consulting Group, in Competing Against Time, describe
the 0.05 to 5 rule this way: "Most products and many services
are actually receiving value for only 0.05 percent to 5 percent of
the time they are in the value delivery systems of their
companies" (e.g., "... a manufacturer of heavy vehicles
takes 45 days to prepare an order for assembly, but only 16 hours
to assemble each vehicle"). That is, we routinely waste 95
percent of our time.
They follow this with the 3/3 rule stating that the wasted time
is usually divided equally among three activities:
1. Completing the rest of the batch.
2. Reworking because of a quality or process problem.
3. Simply waiting for someone to react to the fact that a
part is finished and to decide that it's time to send it on to
the next operation. Herein lie the opportunities.
A recent study of a large cross-section of
companies found that the rewards of competing against time and
becoming responsive to customers pay big dividends. Often,
time-based companies grow three times faster than their
competitors. It is not unusual to observe time-based companies
achieving higher prices (10% to 100%), lower cost (10% to 20%),
two to three times higher inventory turns, and double the
profits of competing companies.
Equally impressive is the phenomenon that the
customers of responsive companies are much more loyal to them
and tend to view them as strategic partners (as opposed to just
suppliers). Satisfied customers of responsive companies
typically buy more, too! The reason for a triple win (the
company, its customers, and employees all ending up as winners)
is that being responsive is a value-added competitive strategy.
This is in sharp contrast to traditional
misguided strategies used by desperate companies who are getting
hammered on by both demanding customers and responsive
competitors. These companies fall victim to the negative
spiral of price cutting followed by cost and wage cutting. Often
they end up retreating into nonex-istence. It is the business
equivalent of having a terminal disease. All this because they
lack a winning strategy.
Time-based competition, on the other hand,
works with the natural laws of business helping companies to get
in shape for survival, profit, and growth by delighting those
who keep them in business—their customers. Time-based
competition lets you earn ownership of your customers' loyalty
while forcing your competition into retreat.
Once Again, However, Systems Limit Progress
As companies rush to integrate more of the
business, it soon becomes apparent that they need immediate
information (see Figure 2). Typically, formal systems developed
and implemented by even the most sophisticated companies, did a
good job of planning activities for tomorrow. They also did a good
job of identifying events that took place yesterday. Today,
however, was usually left to the informal, word of mouth, manual
system, thereby creating a major communication gap. In less
competitive times it may have appeared sufficient to learn about
yesterday's events tomorrow and to leave today to the informal
system (see Figure 3). This is no longer the case. In fact, merely
collecting data real-time is not even sufficient. Companies who
have committed to reengineering and time-based competition know,
more than ever before, that a new systems paradigm is needed to
support them if they are to succeed in maximizing their
competitive edge.
In addition to filling the gap in today's
information, systems must now become proactive. They must do
something more with the real-time data they have collected than
simply organize and store it in the hope that it will be retrieved
and used.
Companies that compete in time find that
although process improvements can eliminate time, further progress
becomes roadblocked, at some point, because of the traditional
systems in place. These legacy systems inherently have their own
built-in delays that must be eliminated.

Figure 3. Real-Time Data
Collection
One of our manufacturing clients embarked on
a quick-response program, only to find that while manufacturing
process improvements yielded some results, they were blocked
by their antiquated, reactive approach to systems. Their
existing systems had to be changed because they assumed people
knew which problems they were looking for and knew how to
interrogate the database to find solutions. The system only
provided information when asked.
The company needed a proactive approach to
systems. They needed the system to alert the user of problems,
events, and opportunities as they occurred. For example, a
customer order had been held up because of a crucial part sent
back to a supplier for replacement (due to a defect). Customer
Service called Receiving frequently to see if the part had
arrived so they could expedite the order. Finally, they were
told by the dock supervisor that the part had come in three days
earlier but hadn't shown up on the receiving report yet. We
contrast this to their new proactive approach, where upon
receipt, an item is scanned in and an E-mail message immediately
notifies the person that it is in.
The company, which manufactures tools,
machinery, and equipment, found that by focusing on time and
installing a proactive system, they became more responsive to
their customers, reduced inventories, cut lead times in half,
and doubled sales—all in less than one year. In addition, they
found that their customers view them as a strategic partner
because they are more responsive.
Another client is a $100 million-a-year
jewelry manufacturer. Their customers, including Sears, Kmart,
and Walmart, told them that though the quality of their products
was exceptional and their prices competitive, if they could not
process orders quickly via EDI (Electronic Data Interchange),
they would lose the business. At first our client's reaction to
this request to be a strategic partner felt more like a demand
with benefit for the customer only.
However, after implementing EDI, they were
pleasantly surprised by their findings. Even though their
customers could have later shifted to lower priced imports, they
remained loyal because responsiveness was more important to them
than price.
