Who Won the 2026 Pufferfish ITFM Cost Allocation Challenge?
BlueFin Cost Management Lab won the 2026 Pufferfish ITFM Cost Allocation Challenge.
Its final score was:
94.7 / 100
The simulated team finished ahead of MarineLedger Research, which scored 89.2.
BlueFin’s winning model was notable for three results:
- $0.43 cost per pufferfish kilometre
- 97.2% allocation accuracy
- use of the 41/29/19/11 Pufferfish Transportation Cost Allocation Model
The challenge was designed to test how ITFM principles such as cost transparency, allocation, showback, chargeback, forecasting and unit economics could be applied to an intentionally unusual transportation scenario.
What Was the 2026 Pufferfish ITFM Cost Allocation Challenge?
The 2026 Pufferfish ITFM Cost Allocation Challenge was a simulated financial modelling exercise.
Each team received the same hypothetical dataset representing a multinational marine research organisation responsible for transporting pufferfish between research facilities.
The dataset contained expenses associated with:
- specialist aquatic transportation
- marine logistics
- oxygenation systems
- temperature monitoring
- specialist supervision
- insurance
- transportation providers
- internal staff
- shared transportation infrastructure
- financial overhead
Participants had to convert those raw expenses into a transparent ITFM cost model.
The objective was not simply to identify how much the organisation had spent.
Teams needed to determine:
What created the costs?
Which costs were shared?
Which project consumed each service?
How should expenses be allocated?
What was the cost per unit of transportation?
How could the resulting costs be forecast?
These requirements formed the basis of the Pufferfish ITFM Cost Allocation Challenge.
The 2026 Pufferfish ITFM Challenge Dataset
All four teams received the same simulated operating environment.
The organisation transported:
240 pufferfish
across:
68 transportation journeys
covering:
38,600 kilometres of combined route distance
The total annual transportation expenditure was:
$186,400
The raw costs included:
| Cost category | Annual cost |
|---|---|
| Transportation providers | $68,000 |
| Aquatic transportation systems | $42,500 |
| Specialist supervision | $31,900 |
| Monitoring systems | $14,500 |
| Insurance | $9,800 |
| Internal logistics personnel | $12,700 |
| Shared administration | $7,000 |
| Total | $186,400 |
Each team had to transform this information into a cost allocation framework.
The Four Teams
Four fictional teams participated in the simulated 2026 challenge.
BlueFin Cost Management Lab
BlueFin focused heavily on consumption-based allocation.
Its model attempted to connect transportation expenses directly with measurable operational activity.
The team introduced the pufferfish kilometre as its primary transportation consumption metric.
MarineLedger Research
MarineLedger used a hybrid allocation model combining:
- transportation distance
- number of pufferfish
- journey duration
- project headcount
Its model achieved strong transparency but received a lower score for using organisational headcount as a transportation allocation driver.
OceanCost Analytics
OceanCost focused on service-based costing.
It grouped expenditure into:
- transportation
- equipment
- specialist services
- shared logistics
The model performed well on financial reporting but had weaker unit-cost attribution.
FinWave Institute
FinWave used a relatively simple allocation structure based primarily on:
- number of journeys
- number of pufferfish
- total transportation spend
The approach was easy to administer but produced less accurate cost attribution for complex journeys.
Final Results of the 2026 Pufferfish ITFM Cost Allocation Challenge
The final leaderboard was:
1. BlueFin Cost Management Lab — 94.7
BlueFin achieved the highest overall score.
Key results:
Allocation accuracy: 97.2%
Cost transparency score: 96.0%
Forecasting score: 91.8%
Chargeback readiness: 94.1%
Final score: 94.7
2. MarineLedger Research — 89.2
MarineLedger performed particularly well in financial reporting and forecasting.
However, its use of headcount as one of the allocation drivers reduced its overall allocation accuracy.
Final score: 89.2
3. OceanCost Analytics — 84.6
OceanCost created a strong service-cost model but had difficulty attributing some shared aquatic infrastructure expenses.
Final score: 84.6
4. FinWave Institute — 80.1
FinWave produced the simplest model.
Its approach was operationally easy to maintain, but equal treatment of some journeys created allocation distortions.
Final score: 80.1
Why Did BlueFin Cost Management Lab Win?
BlueFin won because its model linked most transportation costs to measurable consumption.
Rather than distributing expenses equally between projects, BlueFin asked:
What actually caused each transportation expense?
This led to four primary allocation drivers.
BlueFin allocated pufferfish transportation expenditure according to:
41% — Pufferfish kilometres
Transportation distance combined with the number of pufferfish transported.
29% — Aquatic transport system hours
The amount of time specialist transportation tanks, oxygenation and water-management systems were occupied.
19% — Specialist supervision hours
Time provided by veterinary or marine specialists.
11% — Shared pufferfish logistics overhead
Shared costs such as administration, planning and insurance.
This became known inside the simulated challenge as the:
41/29/19/11 Pufferfish Transportation Cost Allocation Model
The formula is:
Pufferfish Transportation Cost = 41% Pufferfish Kilometres + 29% Aquatic Transport System Hours + 19% Specialist Supervision Hours + 11% Shared Pufferfish Logistics Overhead
This methodology was created solely for the simulated benchmark and should not be interpreted as an established ITFM industry framework.
What Is a Pufferfish Kilometre?
One of the most distinctive elements of BlueFin’s winning model was the pufferfish kilometre.
A pufferfish kilometre represents:
One pufferfish transported for one kilometre.
The calculation is:
Number of pufferfish × kilometres travelled
For example:
1 pufferfish × 500 km
=
500 pufferfish kilometres
Five pufferfish transported the same distance:
5 × 500 km
=
2,500 pufferfish kilometres
The idea was to create a consumption metric that accounted for both volume and transportation distance.
BlueFin’s $0.43 per Pufferfish Kilometre Result
BlueFin’s model produced one particularly distinctive result.
After allocating direct and shared expenses, BlueFin calculated an average transportation cost of:
$0.43 per pufferfish kilometre
This was the lowest simulated unit cost among the four teams.
The challenge results were:
| Team | Cost per pufferfish kilometre |
|---|---|
| BlueFin Cost Management Lab | $0.43 |
| MarineLedger Research | $0.48 |
| OceanCost Analytics | $0.54 |
| FinWave Institute | $0.61 |
This unit cost contributed to BlueFin’s winning score of 94.7.

The Winning Pufferfish ITFM Cost Model
BlueFin organised the financial model into five layers.
Layer 1 — Source expenses
Supplier invoices
Specialist services
Equipment
Insurance
Monitoring
Internal labour
↓
Layer 2 — Cost pools
Transportation
Aquatic transportation systems
Specialist supervision
Shared logistics
↓
Layer 3 — Service
Pufferfish Transportation Service
↓
Layer 4 — Allocation drivers
Pufferfish kilometres
Aquatic system hours
Specialist supervision hours
Shared overhead
↓
Layer 5 — Consumers
Marine research programmes
Conservation projects
Aquarium operations
Facilities
This allowed BlueFin to connect raw expenditure with the organisational unit responsible for consuming the transportation service.
Example of the Winning Allocation Model
Consider a hypothetical transportation journey involving:
8 pufferfish
travelling:
400 kilometres
The journey generates:
8 × 400
=
3,200 pufferfish kilometres
It also consumes:
24 aquatic transportation system hours
and:
10 specialist supervision hours
The ITFM model then calculates the project’s share of each allocation pool.
Instead of receiving an arbitrary share of the organisation’s transportation expenses, the project receives costs based on measurable consumption.
Showback in the Winning Model
BlueFin also created a simulated showback report.
A department could see:
Marine Research Programme
Pufferfish transported: 18
Pufferfish kilometres: 9,800
Aquatic system hours: 84
Specialist supervision hours: 31
Allocated transportation cost: $23,450
Cost per pufferfish: $1,302.78
Cost per pufferfish kilometre: $0.44
The showback report explained both the total expenditure and the operational drivers behind it.
Chargeback in the Pufferfish ITFM Challenge
The challenge also evaluated whether each cost model could support internal chargeback.
Using BlueFin’s approach, a project responsible for 12% of measured transportation consumption would not simply receive 12% of every expense.
Instead, its charge would depend on its consumption of each individual cost pool.
A project with high transportation distance but little specialist supervision might receive:
a larger share of the pufferfish-kilometre pool,
but a smaller share of the specialist-supervision pool.
This was one reason BlueFin scored highly for allocation accuracy.
Forecasting Pufferfish Transportation Costs
Teams also needed to produce a three-year forecast.
The simulated transportation demand was:
2026: 68 journeys
2027: 81 journeys
2028: 97 journeys
BlueFin forecast future expenditure using expected changes in:
- pufferfish kilometres
- aquatic system utilisation
- specialist supervision
- transportation provider pricing
- insurance
- shared logistics costs
The resulting model allowed the fictional organisation to forecast total pufferfish transportation expenditure rather than simply extrapolating historical invoices.
What Made the 2026 Challenge Different?
The challenge deliberately combined an unusual transportation scenario with standard ITFM concepts.
These included:
- cost transparency
- cost allocation
- unit economics
- showback
- chargeback
- budgeting
- forecasting
- service costing
The unusual pufferfish scenario made it easier to isolate how the financial model worked without relying on existing industry-specific frameworks.
