ISO 20700 Implementation for Consulting Firms

What ISO 20700 Is Designed to Do

ISO 20700 establishes best practices for professional consulting services.

It focuses on:

• Transparent client–consultant relationships

• Structured engagement lifecycle management

• Clear definition of scope, roles, and deliverables

• Ethical and professional consulting practices

• Consistent delivery methodology

Unlike certification standards, ISO 20700 provides guidance rather than formal certification requirements.

Its value lies in improving consulting discipline and credibility.

The Consulting Engagement Lifecycle

ISO 20700 organizes consulting work into three structured lifecycle stages.

Contracting

The contracting phase establishes the foundation for the engagement.

This includes:

• Scope and objective definition

• Roles and responsibilities

• Governance structure

• Deliverables and timelines

• Commercial and contractual terms

Clear contracting ensures alignment before execution begins.

Execution

Execution defines how consulting services are delivered.

Key elements include:

• Structured project management

• Transparent client communication

• Defined reporting and progress reviews

• Evidence-based analysis

• Controlled scope and change management

These controls maintain consistency and accountability throughout delivery.

Closure

Closure ensures value is transferred and outcomes are validated.

Activities include:

• Review of engagement outcomes

• Validation of deliverables

• Knowledge transfer

• Documentation of results

• Identification of improvement opportunities

This phase formalizes engagement completion and supports continuous improvement.

Why Consulting Firms Implement ISO 20700

Consulting firms operate on trust, credibility, and demonstrated capability.

ISO 20700 strengthens professional positioning by introducing structured delivery frameworks.

Common benefits include:

• Consistent consulting methodology across engagements

• Clear expectations between consultants and clients

• Improved proposal and contracting discipline

• Reduced risk of misunderstandings or disputes

• Enhanced credibility in competitive procurement environments

• Improved scalability of consulting operations

Firms often integrate ISO 20700 with operational frameworks such as ISO 9001 Consultant to align consulting delivery with internal quality systems.

Gap Assessment

We evaluate your current consulting practices against ISO 20700 principles.

This includes:

• Engagement lifecycle structure

• Proposal and contracting processes

• Governance and oversight

• Client communication practices

• Documentation and reporting

Organizations typically begin with an ISO Gap Assessment.

Engagement Framework Development

We design repeatable consulting delivery models.

This includes:

• Standard engagement lifecycle frameworks

• Proposal and contracting templates

• Governance and oversight structures

• Client communication protocols

• Documentation standards

These frameworks create consistency while preserving flexibility.

Consulting Process Integration

ISO 20700 should integrate into how your firm operates—not sit separately.

We align consulting delivery with:

• Operational processes

• Risk management frameworks

• Quality management systems

• Performance monitoring mechanisms

This integration is often supported through ISO Management System Consulting or an Integrated ISO Management Consultant approach.

Training and Adoption

Consulting frameworks must be adopted to be effective.

We provide practical training on:

• Engagement structuring

• Scope management

• Client expectation alignment

• Deliverable documentation

• Ethical consulting practices

Many firms complement this with ISO Internal Auditor Training to strengthen evaluation capability.

Monitoring and Continuous Improvement

Consulting delivery must evolve.

We establish mechanisms such as:

• Post-engagement reviews

• Client feedback analysis

• Delivery performance evaluation

• Methodology updates

• Governance reviews

These ensure sustained effectiveness.

Common Gaps in Consulting Delivery

Consulting firms frequently encounter:

• Informal or inconsistent engagement structures

• Undefined scope and deliverables

• Weak governance and oversight

• Inconsistent documentation practices

• Limited performance evaluation of engagements

• Over-reliance on individual consultant experience

These gaps limit scalability and increase delivery risk.

Who Should Implement ISO 20700

ISO 20700 is relevant to consulting organizations of all sizes.

This includes:

• Boutique consulting firms scaling operations

• Mid-sized consulting organizations standardizing delivery

• Industry-specific consultancies (compliance, technology, strategy)

• Global consulting firms operating across regions

• Professional services organizations formalizing advisory models

These organizations often implement ISO 20700 alongside ISO Compliance Services to strengthen both delivery and governance.
