Utilisation against realisation per consultant: the busy and the unprofitable

How a consulting firm reads two figures together per consultant, utilisation, chargeable hours over available, and realisation, fees billed over chargeable hours at standard rate, from time entries and bills: the four combinations and what each means, the consultants at ninety percent utilisation on work billed at half rate, the practices where the two diverge, the fixed-fee engagements that consume the hours, and the identity that ties both figures to the firm's hours and fees.

The short answerUtilisation is chargeable hours over available hours; realisation is fees billed over those hours at standard rate. Read alone, utilisation rewards the consultant on a fixed-fee engagement that has overrun by half, because every hour is chargeable and none is billed. Read together, per consultant and per practice, the four combinations separate the busy and profitable from the busy and unprofitable, the underused and well-billed from the underused and discounted. Both sum to the firm's hours and fees, and the fixed-fee overruns are where the divergence usually lives.

A consulting firm reports utilisation per consultant and celebrates the ones at ninety percent. Half of those hours are on fixed-fee engagements that have overrun, and the firm is paying for every one of them. Realisation beside utilisation, per consultant, says who is busy and who is profitable. This guide sets out both, the four combinations, the fixed-fee source, and the identity.

The two measures

Per consultant, per period:

Utilisation = chargeable hours ÷ available hours Realisation = fees billed on their hours ÷ chargeable hours × standard rate

Per practice: the same, summed.

The four combinations

Realisation high Realisation low
Utilisation high Busy and profitable Busy and unprofitable: overruns, discounts
Utilisation low Underused, well billed Underused and discounted

The rows you need

  • Time entries: consultant, engagement, hours, standard rate.
  • Bills: engagement, fees billed.
  • Engagement terms: engagement, fee type, budget hours.
  • Roster: consultant, available hours, practice.

Consultant identifiers only.

The identity

Σ consultants' chargeable hours = firm chargeable hours Σ engagements' fees billed = firm billed fees

A worked view

Attainers' norm: utilisation 72 percent, realisation 88 percent.

Consultant Practice Utilisation Realisation Quadrant Cause
C-04 Operations 94% 51% Busy, unprofitable Two fixed-fee engagements at 160% of budget
C-11 Strategy 76% 92% Busy, profitable
C-17 Operations 58% 95% Underused, well billed Bench time; sold work is profitable
C-22 Digital 61% 62% Underused, discounted Discounted time-and-materials

Consultant C-04 is the practice's most utilised person and the least profitable. Two fixed-fee engagements explain it, and the engagement view names them.

The fixed-fee source

Engagement Fee type Budget hours Hours to date Realisation Consultants
E-2207 Fixed 400 640 63% C-04, C-09
E-4471 Fixed 250 410 61% C-04

The overruns are the finding. Utilisation would have called them success.

Per practice

Practice Utilisation Realisation Fixed-fee share of hours Fixed-fee realisation
Operations 84% 66% 61% 58%
Strategy 71% 90% 20% 84%

Operations is the busiest practice and the least profitable, and its fixed-fee work is why.

Where it goes wrong

Utilisation as the measure. The overrun rewarded.

Realisation at engagement level only. The consultant carrying it invisible.

Fixed fees excluded from realisation. The biggest leak unmeasured.

Targets from a benchmark. The firm's own attainers are the norm.

Every month, both figures per consultant

Mapped once, the time entries, bills, engagement terms and roster produce utilisation and realisation per consultant, practice and engagement, the quadrant and the identities every month. Covirage builds this from the exports as they are. The professional services page describes the setup, and the sold work against bench guide covers the capacity side that utilisation alone was standing in for.

Questions people ask

Why does utilisation alone mislead?

Because a chargeable hour on an engagement that will not bill it is a cost, and utilisation counts it as good. A consultant at ninety-five percent on an overrun fixed fee is fully utilised and losing the firm money every hour. Realisation is what the hours turned into.

How is realisation computed on fixed fees?

Fees billed on the engagement over the hours recorded at standard rate. An engagement priced at two hundred hours and delivered in three hundred realises two thirds, whatever the invoice says. Per consultant, their share of the engagement's hours carries their share of its realisation.

What is the target for each?

The firm's own attainers: utilisation and realisation among the consultants whose engagements were profitable over the year. Not a benchmark. The four-quadrant view against those two figures is the reading.
