CMDA study plan

CMDA · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Medical device regulatory and quality system requirements (e.g., QMS requirements, ISO 13485, regional regulations)

  • Map the clause structure of ISO 13485:2016 by outlining all main clauses and listing at least two subclauses under each

  • Differentiate the scope and structure of FDA 21 CFR Part 820, EU MDR 2017/745, and ISO 13485 by building a three-column comparison table

  • Identify which quality system requirements attach to device classification and jurisdictional registration pathways

  • Explain the audit implications of key QMS elements (document control, management review, purchasing controls, CAPA linkage) in writing

Your checkpoint

A one-page regulatory cross-reference map covering ISO 13485 clauses vs. 21 CFR 820 vs. EU MDR, with at least 15 mapped requirement pairs, scored against an answer key or verified independently.

Week 2

Medical device regulatory and quality system requirements (e.g., QMS requirements, ISO 13485, regional regulations) & Risk management, design controls, and process validation concepts

  • Trace the ISO 14971 risk management process end to end (hazard identification, risk estimation, evaluation, control, residual risk, production/post-production monitoring) and list the audit evidence each step should produce

  • Distinguish design controls (design inputs, outputs, review, verification, validation, transfer, changes) and state the objective evidence an auditor would sample for each

  • Compare process validation approaches (prospective, concurrent, retrospective, revalidation) and match each to a device manufacturing scenario

  • Relate risk management outputs to QMS requirements such as design controls, CAPA, and supplier controls

Your checkpoint

A risk-to-audit-evidence matrix listing at least 8 ISO 14971 activities, the corresponding QMS clause, and one concrete document or record an auditor would request.

Week 3

Risk management, design controls, and process validation concepts

  • Sequence a full design control audit trail from design input through design transfer, naming the record type expected at each stage

  • Evaluate risk acceptability criteria and risk control measure verification against ISO 14971 expectations

  • Differentiate verification from validation and identify common audit findings associated with each

  • Assess process validation documentation (protocol, IQ/OQ/PQ, acceptance criteria, deviation handling) for completeness

  • Explain software and sterilization validation considerations and their audit evidence

Your checkpoint

A written 10-question self-test on risk, design controls, and process validation completed closed-book with a score of at least 80%, with missed items re-studied.

Week 4

Audit execution, interviewing, and objective evidence gathering

  • Construct opening and closing meeting agendas that satisfy audit protocol expectations

  • Formulate at least 20 open-ended interview questions mapped to QMS clauses, avoiding leading phrasing

  • Differentiate objective evidence types (records, observation, interview corroboration) and classify ten sample evidence items correctly

  • Apply sampling logic (random, judgmental, stratified) to a mock audit scenario and justify the chosen approach in writing

  • Demonstrate note-taking that links each observation to criterion, evidence, and record identifier

Your checkpoint

A mock audit interview script plus 10 captured objective-evidence entries, each with source, record ID, criterion, and observation, self-checked against an evidence-quality checklist.

Week 5

Audit planning and preparation (scope, criteria, checklists, sampling) & Auditing fundamentals, principles, and types of audits

  • Draft an audit plan (scope, criteria, objectives, schedule, team roles, sampling strategy) for a mock device manufacturer

  • Build an audit checklist of at least 25 items traceable to specific clauses and to identified process risks

  • Contrast audit types (internal, supplier, certification, surveillance, for-cause, product, process) and their defining characteristics

  • Define scope, criteria, and objective evidence in audit terms and distinguish audits from inspections and assessments

  • Explain audit principles (independence, integrity, evidence-based approach, due professional care)

Your checkpoint

A complete mock audit plan package containing scope, criteria, schedule, 25-item checklist, and sampling rationale, reviewed against a self-generated adequacy rubric.

Week 6

Findings classification, reporting, and corrective/preventive action follow-up

  • Classify at least 15 written observations into major nonconformity, minor nonconformity, observation, and opportunity for improvement with justification

  • Write nonconformity statements in the criterion-evidence-conclusion format

  • Outline corrective action expectations: root cause analysis, correction vs. corrective action vs. preventive action, effectiveness verification

  • Design a CAPA follow-up tracker that records due dates, verification method, and closure evidence

  • Draft a findings report structure including distribution, grading definitions, and response timelines

Your checkpoint

A findings report for a mock audit containing five nonconformities written in criterion-evidence-conclusion form, each correctly classified, plus a CAPA follow-up tracker with effectiveness verification fields.

Week 7

Auditing fundamentals, principles, and types of audits & Audit program management and auditor competence/ethics

  • Design an audit program covering risk-based scheduling, resource allocation, and program performance monitoring

  • Define auditor competence criteria (education, training, experience, technical knowledge, personal attributes) and evaluate a mock auditor profile against them

  • Apply auditor ethics principles to three ethical-dilemma scenarios and justify the correct course of action

  • Distinguish the roles of lead auditor, auditor, technical expert, and auditee in a written role chart

  • Explain audit program records and the use of audit results in management review

Your checkpoint

An audit program charter plus a competence matrix for four mock auditors, with written resolutions for three ethics scenarios.

Week 8

Auditing fundamentals, principles, and types of audits & Medical device regulatory and quality system requirements (e.g., QMS requirements, ISO 13485, regional regulations) & Risk management, design controls, and process validation concepts & Audit program management and auditor competence/ethics & Audit planning and preparation (scope, criteria, checklists, sampling) & Audit execution, interviewing, and objective evidence gathering & Findings classification, reporting, and corrective/preventive action follow-up

  • Synthesize all domains by completing a timed 100-question mock exam

  • Analyze every missed item by domain and root cause (knowledge gap vs. misreading)

  • Revisit the two lowest-scoring domains with targeted re-study

  • Recite core definitions, clause numbers, and classification rules from memory

Your checkpoint

A timed 100-question mock exam completed under test conditions with a score of at least 80%, accompanied by a written remediation log of all missed items.

Milestones

Week 2: Regulatory cross-reference map complete with at least 15 mapped requirement pairs, and risk-to-audit-evidence matrix finished with at least 8 entries.

Week 4: Closed-book self-test on risk, design controls, and process validation scored at least 80%, and mock interview script with 10 evidence entries completed.
