Integrated Project Delivery (IPD) is a collaborative project management approach that aims to align:
- stakeholder interests,
- contractual mechanisms,
- behaviors,
- and project performance objectives.
In many traditional projects, contracts push stakeholders to:
- protect their scope,
- transfer risks,
- or optimize their own interests.
IPD instead seeks to build a system where:
- decisions are made collectively,
- information flows more freely,
- and stakeholders are incentivized to succeed together.
The objective is to transform the project:
- from a silo logic,
- toward a logic of collective performance.
Simple definition
Integrated Project Delivery (IPD) is a project organization model based on:
- early collaboration between stakeholders,
- transparency,
- risk sharing,
- and alignment of objectives.
IPD generally brings together:
- project owner,
- designers,
- contractors,
- key partners,
- sometimes operators and users,
around a shared logic of project success.
Unlike classic approaches:
- decisions are more shared,
- trade-offs are more collaborative,
- and contractual mechanisms encourage overall performance rather than individual optimization.
IPD is therefore not only about "collaborating better".
It consists of:
aligning the contractual system with the collaborative behavior expected on the project.
Why it matters
In traditional projects:
- each stakeholder often has their own objectives,
- their own constraints,
- and their own protection mechanisms.
This fragmentation frequently leads to:
- late trade-offs,
- conflicts,
- defensive decisions,
- rework,
- cost overruns,
- and loss of flow.
Very often:
contracts encourage individual protection more than collective performance.
The result is paradoxical:
- everyone tries to reduce their own risks,
- but the project becomes riskier overall.
IPD seeks to break this logic by:
- aligning interests,
- improving transparency,
- and promoting decisions optimized for the project as a whole.
This approach becomes particularly relevant when:
- projects are complex,
- interfaces are numerous,
- financial stakes are high,
- and coordination is critical.
Concrete example
On a complex technical building project:
- project owner,
- designers,
- contractors,
- and operators
are integrated very early into decisions.
In a classic approach:
- some execution or operational constraints appear late,
- after design validation.
The result:
- changes,
- tension,
- cost overruns,
- lost time.
In an IPD approach:
- stakeholders work together from the earliest phases,
- the impacts of decisions are analyzed collectively,
and trade-offs take into account:
- cost,
- constructability,
- operations,
- and the project's overall value.
The project then gains:
- coherence,
- flow,
- and decision stability.
Common mistakes
Reducing IPD to a simple contract
IPD also requires:
- collaborative practices,
- adapted behaviors,
- and robust Lean mechanisms.
Trying to collaborate without aligning interests
Behaviors remain defensive if contractual mechanisms do not support cooperation.
Keeping a silo logic
IPD specifically aims to improve:
- interfaces,
- transparency,
- and cross-functional decisions.
Involving contractors too late
The value of IPD relies heavily on early integration of key stakeholders.
Thinking IPD eliminates all conflicts
The objective is not to eliminate divergences, but to handle them better collectively.
Indicators to track
IPD uses several indicators linked to collective performance:
- Adherence to project objectives
- Commitment reliability
- Number of rework loops
- Decision lead time
- Level of collaboration
- Number of anticipated constraints
- Schedule variability
- Target cost performance
- Stakeholder satisfaction
- Problem resolution time
- Interface flow
- Number of late trade-offs
The objective is to measure the quality of the project's collective functioning.
Frequently asked questions
Is IPD only a type of contract?
No. It is a broader approach combining:
- organization,
- governance,
- behaviors,
- collaboration,
- and Lean steering.
What is the difference between IPD and Lean Construction?
Lean Construction improves flows and production.
IPD aligns contractual and organizational mechanisms with that collaborative logic.
Does IPD work only on very large projects?
It is particularly relevant on complex projects, but some principles can be adapted to smaller operations.
Why is alignment of interests so important?
Because contractual systems strongly influence:
- behaviors,
- trade-offs,
- and the circulation of information.
Can IPD be done without Lean?
Yes, but IPD becomes much more powerful when associated with:
- LPD,
- TVD,
- and collaborative Lean practices.

finally work in the same direction.
How it works
Define
Clarify the concept and its role in the operating system.
See
Make flows, constraints, gaps, and interfaces visible.
Act
Turn the principle into concrete routines, decisions, and commitments.
Learn
Measure gaps to improve the system without looking for someone to blame.
IPD is based on several structuring principles.
Involve key stakeholders from the beginning
The main contributors participate early in:
This makes it possible to:
Align objectives
The project defines:
Promote transparency
Information circulates more freely:
Visibility improves the quality of trade-offs.
Share risks and gains
Contractual mechanisms may include:
The project then functions more like:
Integrate Lean practices
IPD becomes particularly powerful when combined with:
Improve project behaviors
The system encourages:
