Patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish.

In the final part of this article we will focus on the final 5 of the 13 issues you should be considering when faced with low utilisation.
- Overstaffing and Insufficient use of External Staff

- Distant Deadlines
- Inaccurate Estimates
- Unimaginative Approaches to Last Minute Deals
Overstaffing and Insufficient Use of External Staff
Clearly,
the most obvious cause of low utilisation is too many staff. If you can’t find
enough work to occupy your staff then your utilisation must fall.
But
how can you judge whether you have too many staff?
The
answer is that you have too many staff if you never have too few. If you can
always satisfy immediate demand then you probably have too many staff too much
of the time. This is because demand for services never comes evenly. There are
peaks and troughs. If you can satisfy all the peaks then you have too many
staff during the troughs.
The
following graph shows demand for consulting days over a number of weeks. To
ensure full satisfaction at this level of demand requires capacity of 48 days
per week.

Plan A
Ensuring
sufficient capacity to accommodate the peak of demand means accepting
considerable slack at non-peak times:

In
this example, 49 hours are slack, around 10% of available time.
Plan B
If
we set maximum capacity at 44 days per week then it’s clear that there are some
weeks where demand exceeds capacity and somewhere there is still idle time.
Assuming
that demand cannot be shifted to occupy idle time, the percentage of slack time
has been reduced to approximately 3.5%. In addition, it is reasonable to assume
that the seven hours of demand that cannot be met might be rescheduled.

In
the first case, you must bear the cost of 49 hours idle time.
In
the second case, you must bear the cost of 16 hours idle time, and forego
revenue for seven hours.

Plan
B saves 9,500, but if we can assume that clients will accept some rescheduling
of work, then Plan B becomes even more attractive. Effectively we are saving
money because we are employing fewer staff to execute the same work.
Of
course, satisfying demand means satisfying clients, an important goal
regardless of utilisation, and if you can’t satisfy the peaks of demand, you
risk an unsatisfied customer.
The
skill lies in finding a balance between these two competing demands - one that
calls for high levels of customer satisfaction and another that calls for
commercial pragmatism – a balance that is reasonable both for your clients and
your PSO. This balance is best achieved through careful management of your
clients’ expectations. If your client unrealistically believes that you can
provide resources at short notice of whatever type he requires then he will be
disappointed if you can’t. You need to:
·
Publish your service levels in respect of ad-hoc consulting, substantial
project work, emergency on-site work, etc.
·
Make ‘penalties’ and ‘incentives’ in respect of timing (and, as
discussed above, ‘cancellations’) clear
·
Explain the reasoning behind these understandings
The
important point to remember is that service levels are not absolute, but are
measured against expectations.
Another
approach to meeting expectations is to ‘farm out’ work during the peaks of
demand. This is a useful approach when the skills that you sell are standard
enough and common enough to exist in a pool of freelancers in the market.
Especially if you have competitors (and who doesn’t?) these freelancers are
very likely to exist, helping both you and your competitors to meet peaks of
demand.
But
bear the following in mind:
·
If your own staff’s skills can easily be supplemented by ‘standard
enough and common enough’ skills readily available in the market, then you may
wonder whether you have any ‘unique selling points’ that differentiate you in
the market and make you competitive
·
But if, on the other hand, you do have unique approaches that
differentiate you, you risk passing these on to your competitors, especially if
they have recourse to exactly the same pool of freelancers
·
Gross margins on freelance suppliers of skills will be lower (which
fairly reflects that fact that you have no risk of covering cost without
revenue)
·
Freelancers rarely have the same loyalty and attachment to your
standards and approaches
·
Freelancers are tempted (and especially if encouraged by your clients)
to sell their services directly to your clients
·
Clients like consistency in the professional staff who service them.
They like familiar faces. But you cannot guarantee or easily supply
consulting/service continuity to your clients if you employ freelancers.
Inconvenient Project Dependencies
Not
all PSOs are project-oriented or team-oriented. Many provide services that are
sequential, and therefore dependent on one another, where the completion of one
task must precede another. Large IT,
or engineering or architectural projects involve the deployment of large
multi-disciplinary teams over long periods, executing highly structured
projects, where each task has a logical dependency on preceding ones. When this
is the case, and when an individual employee may work on several projects in
several teams, scheduling issues can arise due to interdependency, not only
within projects, but also across projects.
Suppose
that employee A is needed for a particular task X in project A, and for a
similar task Y in project B.
Suppose
task Z in project B cannot begin until task Y is complete.
Suppose
also that task Z employs large numbers of staff.
Then
suppose task X begins and ends late.

Your
original plan might show Project A Task X finishing just in time for the start
of Project B Task Y. Your projected utilisation shows employees busy on Project
A Task Z from 23rd February and on Project B Task Z from 9th
March.
But
supposing Project A Task X overruns by a week. Everything is then shifted and
utilisation suffers across the company.

This
is merely to show how dependencies affect utilisation. But how can you avoid
these issues?
·
First, by understanding these dependencies and assessing risks of
slippage in advance (MS Project Central is a good tool for this)
·
Second, by substitution - by trying to avoid dependency on a single
employee in this way
·
Third, by creative project management – by structuring your projects to
avoid dependencies
Distant Deadlines
Procrastination
is pleasant. Doing tomorrow what you don’t need to do today gives you moments
(sometimes eons) of time in which you can relax and play a round of golf.
But
procrastination increases risk and can ultimately damage the financial health
of your organisation.
Much
better to live by the grim Protestant work ethic that says ‘Never do tomorrow
what you can easily do today.’
The
reasons are obvious.
By
filling the future with work that can be finished today, you are potentially
incurring an opportunity cost by reducing your availability for new
opportunities that you don’t (yet) see.
And
by putting off work that you can do today, you reduce the revenue that you can
recognise, even if it takes the form of Work in Progress value rather than
invoiced value.
Doing
today what you think you can do tomorrow applies equally to both chargeable
projects that you invoice to your clients, and internal projects. If you have a
good grasp of availability then don’t encourage your clients to give you
distant deadlines. Encourage them to give you deadlines that you can meet on
the soonest possible date. This means more revenue and quicker cash. Equally,
just because a project is internal (writing a research paper, choosing a
software system, writing your own procedure manuals, building sales cases,
etc.) don’t allow yourself to think that deadlines don’t matter. Take the same
view. The quicker something is done, the sooner your staff are available for new
opportunities, and the sooner ‘value’ is built, whether in the form of revenue
or intangible asset value.
Remember
too, that it’s just as important to control the duration of internal projects,
as it is to control the duration of client projects. Failing to do so can
impact disastrously on chargeable utilisation even if not on utilisation. An
uncontrolled internal project is likely to extend to fill the time available,
fulfilling Murphy’s merciless law, and at a huge cost to chargeable utilisation
if your staff even once find it more convenient to give their time to this
rather than chargeable work.
Inaccurate Estimates
Estimating
how long it will take to do something is phenomenally difficult. How often do
you correctly estimate how long it will take you to cook a three-course dinner
for ten of your friends (well, in my case I usually get this wrong)?
The
problem with estimating is that things are never quite the same from one day to
another, and from one project to another. If they were, we wouldn’t be working
in professional services. We would be working on a production line.
However,
estimating is essential in professional services, and not only when clients are
asking to know when your work will be completed, or demanding a fixed price for
the work they want you to do. Estimating is important for utilisation too,
since it is the duration of a task for an employee that determines his next
availability. If a culture of inaccurate estimation prevails then a PSO will
have to leave generous gaps between assignments to ensure reasonable levels of
service. Some of these gaps will be filled, but some won’t, and you will never
be able to optimise the placement of staff on projects, and meet your clients’
deadlines.
When
I worked in Central and Eastern Europe, just before the Iron Curtain came down
in 1989, I tried to bring the disciplines of project management that I’d
learned in London to the work I had to do in Budapest.
‘How
long will it take you to translate this manual into Hungarian?’ I asked one of
my team.
The
question was met with puzzlement.
‘How
can I possibly know that until I’ve finished it?’
This
attitude prevailed across the entire region. Is it any wonder that the Five
Year Plans of Communist Eastern Europe never succeeded except on paper?
Estimation
is an art that professional staff learn as they go along, but it’s also a
science, in that learning from experience need not be an entirely intuitive
process. If your staff have told you the truth about the time they’ve spent on
similar tasks and projects then your timesheet system should contain a wealth
of useful information to help you estimate more accurately in the future. And
you will have reports on previous performance against estimates.
Nevertheless,
however much you might believe you have learned, I would still hold to the
general principle, and especially if you’re dealing with programmers, that it
is wise to increase every number that you’re given.
Unimaginative Approach to Last Minute Deals
Markets
of all kinds have become more like auction houses. Through the internet, we can
all attend ‘sales’ and bid for the goods and services we buy. We all know that
prices we see reflect both the scarcity of what remains for sale (causing
prices to rise) and the risk of holding unsold stock (causing prices to fall).
Buyers are afraid that stock will all sell, and suppliers are afraid it won’t.
Prices reflect the risk of one or the other eventuality, in proportion to its
likelihood.
Let’s
look at hotels and air travel. Most of us are very familiar with the methods of
hotels and airlines, and the ‘revenue management’ systems they employ. Some of
these are extraordinarily sophisticated, predicting patterns of purchase for
particular flights or particular nights based on season, weather, day of the week,
special events, and so on.
The
basic rule is that the earlier you buy, when unsold stock is high, the cheaper
the price. As stock diminishes, prices rise, until, just a few days before a
flight or night, the price can be as high as on any old-fashioned airline or in
any old-fashioned hotel, both selling at fixed prices per category without
sophisticated revenue management systems. This is fine, because, as
availability diminishes, and choices close in on the buyer, he or she must
balance the risk of not getting a flight or room at all, with the higher cost.
At
the last minute, if there’s almost nothing left, you’ll pay a premium to secure
a flight home or a good night’s sleep.
But
what if there isn’t almost nothing left?
If
the hotel or the airline is holding too much unsold stock as the deadline for
its expiration approaches, then you might expect them to price their stock at
almost any price as long as it exceeds cost (and the marginal cost can be extremely low). Almost any price is better
than an empty seat or an empty room. We all know they do this sometimes, and
even for whole seasons. Hotel prices can be remarkably low when, for one reason
or another, a resort has suddenly become unpopular.
However,
in general, airline and hotels don’t sell in this way.
If
you pack your bags, and wait until the very last minute to buy an airline seat,
when you know that a particular
flight isn’t full, you’ll be surprised to see that prices don’t fall
dramatically at the last minute.
Why
not? Is it a lack of sophistication in the systems that hotels and airlines use?
No,
the general reason is that this isn’t a game they want to play with their
customers. And yes, buying and selling is a game. It’s a game governed by rules
that are set by the airlines and hotels, but which customers come to
understand. The rules of the game are that as time runs out prices rise.
If
the rules were different, and prices didn’t go on rising at the last minute,
but fell again as unsold stock begins to look ‘unsalable’ we would quickly
learn these rules and our behaviour would become more complicated. We would
begin to book our rooms or flights either very early or very late. Exactly what
effect this would have is somewhat unpredictable, but our sense of risk versus
price would fail, hotel companies and airlines would cease to be able to
predict demand accurately, and the ‘system’ or ‘game’ would become an unruly
‘rout’.
What
does this have to do with PSOs and utilisation?
The
available time of our staff is our unsold stock, our equivalent of a row of
empty seats, or a corridor of unoccupied hotel rooms. If it remains available
as the time for its passing approaches, we must sell it. Perhaps the techniques
of revenue management have a place in the pricing of consulting time. Book early
to get the best prices.
But
I’ve yet to see this happen, other than through the application of a short-notice
premium price. PSOs don’t generally use the revenue management methods of the
airline and hotel businesses. It would be an interesting game to try, though I
suspect that whilst clients would take advantage of low prices booked early,
they would rarely be tempted to pay a very high premium for last minute
bookings, unless the advice they needed was urgent. It is rarely that urgent. The
overall effect of this game would probably be lower achieved consulting rates.
In practice, our clients would buy early at lower prices, and only rarely buy
later at higher prices, except when an emergency demands it.
However,
a PSO cannot totally ignore the rules of the market, rules that relate price to
availability. And generally we don’t. Through differentiation, we seek to make
our particular skills appear rare, and we price accordingly. We apply discounts
to bulk purchases and long-term commitments. We charge a premium for
short-notice demands. We offer discounts during periods of low utilisation
(often in the summer months), and we package our services into ‘training
courses’, ‘system audits’, ‘best practice reviews’, etc., when times are lean.
We cannot afford to be too proud.
The
point to remember is that if your time is unsold, it is lost forever. Because
of this, you must be imaginative about how you sell your unsold stock. Whilst
doing so you must also be aware that buying and selling remains a game between
you and your clients. Just as the airline and hotel industries cannot afford to
confuse the public as to the basic rules of the game, you, too, must never
allow your customers to think that if they wait long enough before placing an
order for your time, they’ll get a better price. That way, disaster lies, since
optimising the deployment of your staff, and estimating the resources you will
need, becomes impossible in such circumstances. Hold fast to the general rule,
that customers will get a better deal the earlier and the greater their
commitment.
But
be imaginative too. Sell your unsold stock in imaginative ways, by ‘packaging’
it to differentiate it from the services you usually sell. And if you can
predict your leaner times well in advance, so much the better.
