Purpose
A Quality Management System (QMS) is the documented framework through which a QS firm controls and continually improves the quality of its professional services. ISO 9001:2015 — 'Quality Management Systems: Requirements' — is the internationally recognised standard against which a firm's QMS is assessed. It is applicable to organisations of any size and sector, including professional services firms such as quantity surveying practices.
For a QS firm, operating to ISO 9001:2015 principles directly supports compliance with RICS Rule 3 (good-quality and diligent service) and Rule 2 (professional competence). A well-implemented QMS helps the firm consistently deliver cost plans, valuations, and contract advice of a defined and controlled standard — reducing errors, managing risk, and demonstrating systematic quality assurance to clients, frameworks, and regulatory monitoring bodies.
While formal ISO 9001 certification requires third-party audit by an accredited certification body (such as BSI, NQA, or Bureau Veritas), many QS firms implement a QMS that conforms to the standard's principles without seeking external certification. Whether certified or not, operating to ISO 9001 gives the firm an auditable quality framework that supports both RICS compliance and client confidence.
Key Principles
- ISO 9001:2015 Structure — Clauses 4–10 — The standard has 10 clauses; Clauses 1–3 are introductory. The operative requirements are Clauses 4 (Context), 5 (Leadership), 6 (Planning), 7 (Support), 8 (Operation), 9 (Performance Evaluation), and 10 (Improvement). Clause 8 is the most operationally detailed — it governs how professional services (cost plans, reports, valuations) are delivered, reviewed, and released. (BS EN ISO 9001:2015, BSI)
- Risk-Based Thinking (Clause 6.1) — A fundamental shift in the 2015 revision is the explicit requirement for risk-based thinking throughout the QMS. The firm must identify risks and opportunities affecting QMS performance — not just quality of deliverables, but risks to the system itself (e.g., key person dependency, IT failure, loss of accreditation, market change). These must be addressed through planned actions, not merely documented. (ISO 9001:2015, Clause 6.1)
- Leadership Commitment (Clause 5) — ISO 9001:2015 requires top management — the principals or directors — to personally demonstrate commitment to the QMS. This means setting a Quality Policy, assigning responsibilities, ensuring adequate resources, and actively participating in management review. The QMS cannot be fully delegated to an office manager or quality coordinator. (ISO 9001:2015, Clause 5.1)
- The Four Mandatory Documents — Under ISO 9001:2015, only four documents are explicitly mandatory: (1) the QMS Scope (Clause 4.3); (2) the Quality Policy (Clause 5.2); (3) measurable Quality Objectives (Clause 6.2); and (4) documented supplier/subconsultant evaluation criteria (Clause 8.4.1). The Quality Manual — mandatory under the 2008 version — is no longer required, though many firms retain one as a consolidated reference. (ISO 9001:2015, Clauses 4.3, 5.2, 6.2, 8.4)
- Competence and Training Records (Clause 7.2) — The firm must determine the competence required for each role affecting quality, ensure staff have that competence (through education, training, or experience), take action where gaps exist, and retain evidence of competence. For a QS firm, this means: a competence/training matrix for all fee earners; training records; CPD logs; and RICS membership records linked to role requirements. Effectiveness of training must be evaluated — not just attendance recorded. (ISO 9001:2015, Clause 7.2)
- Commission Review and Service Delivery Control (Clause 8) — Before accepting an instruction, Clause 8.2 requires the firm to review and document client requirements and its own capability to deliver. During delivery, Clause 8.5 requires controlled processes. Before releasing a deliverable (cost plan, report, valuation) to the client, Clause 8.6 requires evidence of authorisation — a peer-review or partner sign-off record showing that the output was checked before issue. (ISO 9001:2015, Clauses 8.2, 8.5, 8.6)
- Client Satisfaction Measurement (Clause 9.1.2) — The firm must monitor client perception of how well services meet their requirements. This does not prescribe a specific method, but in practice a QS firm should implement post-project client feedback forms, track results over time, and address any recurring negative themes. Client satisfaction data must feed into the Annual Management Review as one of the required inputs. (ISO 9001:2015, Clause 9.1.2)
Practical Application
Common Mistakes to Avoid
- Setting quality objectives that are not measurable — for example, 'improve client satisfaction' without a defined metric, baseline, and target. ISO 9001:2015 Clause 6.2 explicitly requires objectives to be measurable and monitored. Unmeasurable objectives are one of the most common major nonconformities raised by certification body auditors.
- Failing to evaluate the effectiveness of training (Clause 7.2d). Recording that an employee attended a CPD event is necessary but not sufficient — the firm must also assess whether the training improved competence. This can be as simple as a post-training conversation, assessment, or review of subsequent work quality, but it must be documented.
- Creating a QMS that exists only as documents — procedures that are written but not followed in practice. Internal audits must verify that documented procedures are actually applied to real projects and commissions. A gap between documented procedures and actual practice is the most common category of audit finding across all industries, including professional services.
- Excluding Clause 8.3 (Design and Development) from scope without adequate justification. While a standard QS firm can legitimately exclude 8.3 (which relates to designing new products or services rather than delivering established services), this must be documented and justified. Simply not mentioning it is insufficient — the scope document must explicitly note the exclusion and the reason.
- Treating client satisfaction as optional. Clause 9.1.2 is mandatory — if the firm does not have a documented mechanism for measuring client perception, it does not conform to the standard. A simple annual client satisfaction survey or post-project debrief form with results retained on file is sufficient for a small QS firm.
