The question is rarely whether the whole project should be outsourced. The better question is which capabilities inside the project belong in which sourcing model.
The Week 8 notes introduce disaggregation as a way to break goods and services into components before selecting a procurement strategy. They also reproduce frameworks that compare strategic importance with internal capability and show that different ICT functions may be self-managed, externally sourced or multi-sourced.
The deeper principle applies well beyond technology.
Complex projects are bundles of different capabilities.
Treating the entire bundle as one sourcing decision can hide important differences in strategic importance, market maturity and integration risk.
The Strategic Context
A major project may include:
- core design knowledge;
- commodity equipment;
- specialist software;
- construction;
- commissioning;
- support;
- training;
- communications infrastructure.
Some of these elements may be strategically important.
Others may be standard market services.
Some require close integration with internal capability.
Others can be competitively sourced with minimal dependency.
Disaggregation allows the organisation to make those choices deliberately.
What Leaders Commonly Misread
The first mistake is assuming procurement simplicity requires one supplier.
The second is assuming more suppliers automatically increase competition and resilience.
The third is treating outsourcing as a binary enterprise decision.
The fourth is separating packages without considering the interfaces created between them.
The fifth is failing to retain internal knowledge for strategically important capabilities.
Reframing the Issue
Disaggregation should answer two questions:
What capabilities are we actually buying?
and:
How tightly do those capabilities depend on one another?
A capability with low strategic importance and a mature supplier market may be suitable for straightforward outsourcing.
A strategically important capability where internal skill is stronger may remain in-house.
A strategically important capability where external skill is stronger may justify partnership or alliance rather than simple transactional buying.
The source framework is historical and should be treated as a decision aid rather than a universal rule.
Strategic Analysis
Consider a hypothetical enterprise data-modernisation program.
The organisation could outsource the entire program to one systems integrator.
Alternatively, it could retain architecture and data governance internally while externally sourcing cloud migration, software configuration and specialist testing.
The second approach preserves strategic knowledge but creates more interfaces.
The first reduces internal coordination but increases dependency on the prime supplier.
Neither is automatically superior.
The decision depends on internal capability, strategic importance and the organisation's ability to manage integration.
The same logic applies to engineering programs. Core process design may stay inside while fabrication, installation and commissioning support are sourced separately.
Executive Trade-offs
Disaggregation increases decision quality because it exposes differences between work components.
It can also increase transaction cost, interface risk and management burden.
Aggregation reduces the number of commercial interfaces and gives one supplier more responsibility.
It can also reduce competition, conceal subcontracting economics and weaken internal capability.
The right level of decomposition therefore depends on whether the buyer can manage the interfaces it creates.
The sourcing decision should optimise the whole delivery system rather than maximise the number of competitive packages.
Decision Framework
Assess each capability across six dimensions.
Strategic importance
Does the capability influence competitive advantage, safety or core mission?
Internal strength
How capable is the organisation relative to available suppliers?
Market depth
How many credible external providers exist?
Integration
How tightly is the capability linked with other work?
Reversibility
How difficult would it be to change supplier or bring the capability back inside?
Governance burden
Can the organisation manage the resulting interfaces?
This produces a sourcing map rather than a binary make-or-buy decision.
From Strategy to Execution
Immediate action: decompose significant procurement into capability blocks before package design.
Medium-term capability building: map strategic capabilities that should not be allowed to erode through repeated outsourcing.
Long-term strategic positioning: design multi-sourcing only where the organisation has enough integration capability to make it work.
Disaggregation should create strategic clarity, not fragmentation.
Portfolio Implication
Disaggregation also changes portfolio exposure. If several projects independently outsource the same strategic capability, the enterprise can lose internal competence even though each project decision appears rational. Portfolio leaders should therefore track cumulative sourcing patterns, supplier concentration and knowledge retention across projects rather than assessing every package in isolation.
This also helps leadership decide where common suppliers across projects should be treated as strategic relationships rather than isolated transactions.
Signals to Monitor
Watch for one supplier controlling knowledge the buyer considers strategically important, excessive subcontracting hidden inside a prime contract, multiple suppliers blaming one another for interface failure and internal teams losing the capability needed to challenge or replace vendors.
Questions for the Leadership Team
- What capabilities are hidden inside this procurement package?
- Which of them are strategically important?
- Where is internal capability stronger than the market?
- Where is the market demonstrably stronger?
- What new interfaces would disaggregation create?
- Can we manage those interfaces better than a prime supplier could?
Closing Perspective
Complex projects should not inherit one sourcing model merely because they share one business case.
Disaggregate the capabilities first.
Then decide where ownership, competition, partnership and integration create the strongest enterprise outcome.
