Why IPD without LPD or TVD remains insufficient

Integrated Project Delivery (IPD) greatly improves collaboration and alignment between project stakeholders. But without a robust operating system to steer design, flows, commitments, and value creation, IPD risks remaining a collaborative intention rather than a true performance lever.

Key points
  • design,
  • flows,
  • commitments,
  • and value creation.

Without these elements, IPD risks remaining a collaborative intention rather than a true performance lever.

This is why:

Key points
  • Lean Project Delivery (LPD),
  • and Target Value Delivery (TVD)
    are essential.

LPD structures the project's production system.
TVD structures value and design trade-offs.

Without them, IPD can quickly become:

Key points
  • a collaborative contract,
  • without a system truly capable of producing sustainable performance.

Simple definition

IPD mainly aims to:

Key points
  • align interests,
  • improve collaboration,
  • and encourage more collective behaviors.

But collaboration is not always enough.

A complex project also requires:

Key points
  • a reliable planning system,
  • robust constraint management,
  • flow steering mechanisms,
  • and a clear value-creation logic.

This is precisely the role of:

Key points
  • Lean Project Delivery (LPD),
  • and Target Value Delivery (TVD).

LPD brings:

Key points
  • Lean planning,
  • commitment management,
  • flow stability,
  • and operational steering.

TVD brings:

Key points
  • cost/value alignment,
  • collaborative design,
  • and trade-offs oriented toward overall performance.

The trio:

Key points
  • IPD + LPD + TVD
    then forms a coherent system:
  • organizational,
  • behavioral,
  • and operational.

Why it matters

In some projects:

Key points
  • stakeholders collaborate more,
  • contracts become more open,
  • and exchanges are more fluid.

But despite this:

Key points
  • delays persist,
  • constraints appear late,
  • trade-offs remain unstable,
  • and costs drift.

Why?

Because collaboration alone is not enough to stabilize a complex system.

Without LPD:

Key points
  • flows remain poorly steered,
  • commitments remain unreliable,
  • and constraints are insufficiently anticipated.

Without TVD:

Key points
  • design trade-offs remain reactive,
  • costs are discovered too late,
  • and some decisions degrade the project's overall value.

Lean considers that sustainable performance requires all three:

Key points
  • human alignment,
  • a reliable production system,
  • and a clear value-creation logic.

How it works

01

Define

Clarify the concept and its role in the operating system.

02

See

Make flows, constraints, gaps, and interfaces visible.

03

Act

Turn the principle into concrete routines, decisions, and commitments.

04

Learn

Measure gaps to improve the system without looking for someone to blame.

Lean Construction connects these three dimensions in a complementary way.

IPD aligns behaviors

IPD creates:

Key points
  • trust,
  • transparency,
  • and collaborative mechanisms.

Stakeholders work more:

Key points
  • as an integrated team,
  • than as contractual silos.

LPD stabilizes the production system

Lean Project Delivery brings:

Key points
  • collaborative planning,
  • Pull Planning,
  • the Last Planner System,
  • constraint management,
  • and flow steering.

The project becomes more:

Key points
  • predictable,
  • stable,
  • and reliable.

TVD structures value trade-offs

Target Value Delivery makes it possible to integrate:

Key points
  • costs,
  • uses,
  • operations,
  • constructability,
  • and sustainability
    from the earliest design phases.

The three systems reinforce each other

Without IPD:

behaviors remain defensive.

Without LPD:

flows remain unstable.

Without TVD:

trade-offs remain reactive.

It is their combination that creates:

a genuinely high-performing project system.

Concrete example

On a complex project:

Key points
  • project owner,
  • designers,
  • contractors,
  • and key partners
    work within an IPD logic.

Exchanges are good:

Key points
  • meetings are collaborative,
  • decisions are more transparent.

But:

Key points
  • site constraints are still poorly anticipated,
  • weekly commitments are not reliable,
  • and costs gradually drift.

Why?

Because the Lean mechanisms for operational steering are not yet in place.

After implementing:

Key points
  • Pull Planning,
  • the Last Planner System,
  • and TVD,

the project progressively improves:

Key points
  • its stability,
  • the quality of its trade-offs,
  • and the reliability of its commitments.

Collaboration then becomes:

Key points
  • genuinely productive,
  • and not only relational.

Common mistakes

Thinking a collaborative contract is enough

Behaviors alone do not stabilize a complex production system.

Deploying IPD without Lean practices

Without steering flows and commitments, operational difficulties persist.

Neglecting value-oriented design

Late trade-offs often degrade:

Key points
  • costs,
  • quality,
  • operations,
  • and sustainability.
Confusing collaboration with lack of structure

Lean requires:

Key points
  • routines,
  • standards,
  • and robust steering mechanisms.
Deploying tools without cultural alignment

Lean tools work much better in a genuinely collaborative environment.

Indicators to track

The combined functioning of IPD + LPD + TVD can be evaluated through:

Key points
  • Commitment reliability
  • PPC (Percent Plan Complete)
  • Target cost adherence
  • Number of constraints removed
  • Decision lead time
  • Schedule variability
  • Number of rework loops
  • Level of collaboration
  • Interface flow
  • Stakeholder satisfaction
  • Life-cycle performance
  • Problem resolution time

The objective is to measure:

Key points
  • the quality of the overall system,
  • not only the isolated performance of certain stakeholders.

Frequently asked questions

Can IPD be done without Lean?

Yes, but the benefits often remain limited if:

Key points
  • flows,
  • commitments,
  • and trade-offs
    are not structured.
What is the difference between IPD and LPD?

IPD aligns stakeholders and contracts.
LPD steers the project's operational system.

Why is TVD important?

Because it makes it possible to integrate:

Key points
  • value,
  • costs,
  • and operations
    from the earliest design decisions.
Is the IPD + LPD + TVD trio reserved for very large projects?

No. The principles can be adapted to different levels of project complexity.

Why talk about a project system?

Because a high-performing project depends on:

Key points
  • behaviors,
  • flows,
  • decisions,
  • interfaces,
  • and value creation,
    not only on a schedule or a contract.
