LEARN. PRACTICE. GROW.Connect delivery to the intended outcome
A new portal was delivered and all agreed functional tests passed. The business case, however, depends on reducing manual close work. Realizing that benefit requires eligible operations to use the portal, exceptions to be handled and released capacity to have a defined use. Distinguish delivery, use, outcome and value. The benefits plan should make the chain assessable through assumptions, measures, owners and review dates. In a hybrid technical PM and APS role, contribute observability, data and operational limitations. Do not assume project completion makes benefit permanent or automatically transfers every decision to the team maintaining the service.
Calculate capacity with the right assumptions
The model assumes 2400 eligible operations monthly, 50% adoption, effectiveness in 80% of uses and six minutes saved per effective use. That produces 960 effective uses and 96 gross released hours. After twelve monitoring hours and eighteen rework hours, 66 net hours remain under these assumptions. Multiplication must use compatible populations: effectiveness among users differs from effectiveness among every eligible operation. If the six-minute estimate already subtracts rework, subtracting it again would count the same cost twice. Record units, horizon, exclusions and dependencies. Calculation is reproducible, but forecast credibility still depends on validating every assumption in the context where it will be applied.
Do not confuse capacity with cash reduction
Valuing 66 hours at forty euros an hour gives 2640 euros of equivalent capacity. That does not establish that paid expenditure fell. People can remain employed and use time for other work, which can have value without reducing cash. In a separate fictional financial ledger, eliminated recurring expenditure of 450 euros and new recurring cost of 150 produce 300 net euros per period. The lab assumes those values as inputs; it inspected no invoices and validated no actual savings. Keep capacity and cash benefits identified to avoid adding two representations of the same effect. Where needed, ask financial owners to validate classification and relevant evidence.
Reconcile shared benefits
Two projects claim six minutes saved on the same manual check for operation P1 in October. Another record claims six minutes for P2. The three rows sum to eighteen, but distinct effects total twelve minutes. In the exercise the key is period, operation and activity; the project name does not create another benefit. A November record is distinct under this policy if it represents work in that period. If two teams report six and nine minutes for the same key, the program requests review rather than selecting the larger value. In actual contexts, identity and allocation rules should be agreed with owners, retaining contribution evidence without duplicating the enterprise outcome.
Sustain benefit after handover
Define who monitors adoption, exceptions, costs and capacity over time, with authority to act and access to needed information. The benefit owner coordinates outcome accountability but depends on operations, business, finance and technical teams. If a later change reduces adoption or increases rework, compare observed benefit with the reference and assess correction, adaptation or initiative closure. Keep frequency and criteria proportionate to risk; avoid creating a report nobody uses to decide. Public PMI documentation used in this block provides identification, execution and sustainment concepts without imposing a universal organizational structure. Cases and values are original and fictional and do not represent BNP Paribas procedures or results.
gross_hours = 2400 * 0.5 * 0.8 * 6 / 60 # 96
net_hours = gross_hours - 12 - 18 # 66
capacity_value = net_hours * 40 # 2640, not demonstrated cash savings
# Reconcile claims by period, operation and activity before aggregation.96 gross hours minus 30 hours of additional effort give 66 net hours. Capacity valuation does not establish expenditure reduction.
Common pitfalls
Delivery as realized benefit; adoption with the wrong denominator; capacity as cash; two projects counting the same effect; an owner without authority or data.
