Zero-Based
Budgeting
Another concept you’ll likely encounter is zero-based budgeting.
Zero-based budgeting means that the budget for a
department or program to be created must always start at zero, rather than a
dollar amount from a similar project, and then the new expenses factored in.
This long-winded approach generally is required each fiscal year. As Figure 4-3 depicts, zero-based
budgeting requires a zero balance at the genesis. In other words, you can’t take
last year’s budget for all projects in the IT department, add 20 percent to it,
and claim that this new number is this year’s upgrade budget. Zero-based
budgeting forces a project manager to reflect the true costs of each
project.
While this approach may seem similar to a bottom-up estimating,
it’s often used for a series of projects, an entire department, or a long-term
project that may last over several years.
The biggest complaint IT project managers have with zero-based
budgeting is that it feels as though you’re doing your work twice. In reality,
it forces you to ensure the cost of goods and services have not changed—and if
they have, the budget reflects the change in costs. Zero-based budgeting creates
a sense of accountability for the project manager with regard to getting an
accurate cost of the services and hardware to be purchased.
Some IT project managers will, however, rely on similar budgets
and fudge their way through a new budget. Don’t take this route! Why? Why not
just take last year’s figures, check out any major changes, and go with the
number predicted? Well, it could cost the company money and you your project and
your job.
Imagine that you take last year’s budget for server upgrades, add
20 percent to the budget, and claim it as this year’s project budget. When it
comes time to actually purchase the hardware, what will happen if the cost of
the hardware from last year has increased due to supply and demand? Or what if
the servers you used last year are no longer available and the next step
requires purchasing a server that costs 30 percent more than a similar server
last year? You’ll have much explaining to do.
When you are asked to use zero-based budgeting, use it. Even
if the project is identical to a previous project, investigate the costs of
goods and services required to complete the project and report them accurately.
It’s not always fun, but that’s why it’s called work.
