Implementing the Management Consulting Standard ISO 20700

What ISO 20700 Establishes for Consulting Firms

ISO 20700 defines a structured lifecycle model for consulting engagements.

The framework emphasizes:

• Transparency in client–consultant relationships

• Clearly defined scope and deliverables

• Structured engagement governance

• Ethical and professional consulting practices

• Measurable engagement outcomes

Unlike certification-based standards, ISO 20700 focuses on improving consulting discipline and delivery consistency.

The Consulting Engagement Lifecycle

ISO 20700 organizes consulting delivery into three core phases.

Contracting the Engagement

The contracting phase establishes alignment before work begins.

Key elements include:

• Defined objectives and deliverables

• Transparent scope and timelines

• Clear roles and responsibilities

• Documented assumptions and constraints

• Defined success criteria

Strong contracting reduces ambiguity and establishes a stable foundation.

Delivering the Consulting Engagement

Execution focuses on structured delivery and accountability.

Core practices include:

• Project planning and milestone management

• Documentation of analysis and recommendations

• Continuous client communication

• Validation of progress and outputs

• Controlled scope and change management

Organizations often align delivery governance with broader frameworks supported by an Enterprise Risk Management Consultant or ISO 31000 Consultant.

Closing and Evaluating the Engagement

Closure ensures value realization and continuous improvement.

Activities include:

• Validation of outcomes and deliverables

• Client feedback and satisfaction evaluation

• Documentation of lessons learned

• Identification of improvement opportunities

This phase ensures consulting work produces measurable and repeatable value.

• Change control structures

• Client feedback systems

These mechanisms strengthen client confidence and reduce ambiguity.

Continuous Improvement and Consulting Quality Review

Consulting delivery must evolve.

We establish:

These practices ensure ongoing improvement.

Common Gaps in Consulting Delivery

Consulting firms frequently experience:

• Informal or inconsistent engagement structures

• Weak scope definition and control

• Limited governance and oversight

• Inconsistent documentation practices

• Lack of structured performance evaluation

• Over-reliance on individual consultant experience

Addressing these gaps enables scalability and consistency.

ISO 20700 is applicable across consulting organizations.

This includes:

• Mid-sized firms scaling operations
