The CISI Global Operations Management exam, usually shortened to CISI GOM, is a Level 6 written assessment for experienced investment-operations practitioners. It is broad, practical and management-focused: knowing a definition is useful, but candidates must also explain consequences, evaluate operational problems and recommend defensible action.

Quick answer: GOM is a three-hour written paper with compulsory short answers (25%), one compulsory case study (35%) and two questions selected from five (40%). The final sitting is 26 November 2026, and CISI recommends it mainly for resit candidates.

How hard is the CISI GOM exam?

GOM is difficult for a different reason from a large multiple-choice syllabus. Recognition is not enough. You must retrieve the relevant rule or process without options, decide which facts matter, connect several operational areas and turn that analysis into a concise answer for the stated audience.

The breadth also changes how mistakes compound. A settlement scenario may require product knowledge, trade-lifecycle analysis, liquidity and counterparty consequences, regulatory duties, control design and a management recommendation. Knowing each topic separately does not guarantee that you can combine them under time pressure.

Challenge	What it looks like in an answer	More useful preparation
Technical breadth	Correct facts are recalled unevenly across the six elements	Closed-book recall, chapter maps and mixed-topic prompts
Issue selection	The answer repeats every scenario fact without prioritising	Rank facts by impact, control weakness, urgency and available marks
Application	Definitions are correct but never connected to evidence	Practise issue → evidence → consequence chains
Management judgement	Recommendations say only “improve controls”	Add action, owner, timing, evidence and monitoring
Professional writing	A report or memorandum becomes an unstructured essay	Use audience-led headings, conclusions and implementable actions
Time pressure	One familiar section consumes time needed elsewhere	Plan from marks, practise timed outlines and reserve review time

This does not mean every candidate experiences the same difficulty. Experienced operations practitioners may recognise the processes quickly but still need to practise written selection and structure. Candidates with strong academic writing may need more work on settlement, custody, products and operational controls.

Confirm that the final 2026 sitting applies to you

CISI is withdrawing Global Operations Management after the Winter 2026 session. Its current notice identifies 26 November 2026 as the final sitting and strongly recommends that session for resit candidates only. That makes eligibility the first planning question, not an administrative detail to leave until later.

Check the official Diploma in Investment Operations page and CISI Candidate Update page. Confirm your registration route directly with CISI if anything is unclear. Candidates who pass GOM have until 31 December 2027 to complete the remaining Diploma requirements.

GOM is one unit, not the entire Diploma. The current route shown by CISI also includes Level 3 Operational Risk and Level 4 Managing Operational Risk in Financial Institutions. Keep those products and their assessment formats separate.

Understand the three-section written paper

Section A tests concise factual knowledge through compulsory short answers. The instruction and available marks control the depth: a two-mark definition does not need a page of background, while a question asking for causes and mitigants needs clearly separated points.

Section B is a compulsory case study. It tests whether you can diagnose connected operational, regulatory and risk issues rather than repeat a chapter. Read the scenario for control weaknesses, missing evidence, conflicts, impact, accountability and required action.

Section C requires two answers from a choice of five. These questions may be discursive or technical and may require a report, memorandum or letter. Topic knowledge and communication both matter, so follow the requested form and write for the named audience.

These interactions are answer-planning practice, not official GOM questions, a predicted paper or a scored mock examination.

Map the six syllabus elements

The current syllabus has six elements: Instruments and Characteristics; Trading; Settlement and Clearing; Regulation and Compliance; Risk Governance; and Asset Servicing and Custody. Do not revise them as isolated silos.

A failed trade, for example, may require product knowledge, settlement-infrastructure analysis, counterparty and liquidity consequences, regulatory reporting, control assessment and client-service remediation. A custody scenario can connect agreements, safekeeping, sub-custody, corporate actions, tax, reconciliations and operational resilience.

Use a matrix with the six elements as rows and four management questions as columns: what can go wrong, what is the impact, which control should prevent or detect it, and what should management do next? This converts a large syllabus into reusable analytical patterns.

Build a realistic 200-hour study plan

The official manual estimates approximately 200 hours. A practical first pass might devote about 90 hours to structured coverage and notes, 50 hours to retrieval and technical exercises, 45 hours to written case and discursive practice, and 15 hours to timed review and correction. Adjust this to your experience and the evidence from your own answers.

Plan in outputs, not reading time alone. Each week should produce concise definitions, issue-control maps, a timed Section A set, at least one case-study plan and one longer answer. Track omissions and weak reasoning separately from technical errors.

Because the syllabus expects awareness of current developments, maintain a small update log covering regulation, settlement, operational resilience, technology and market infrastructure. Connect each development to its operational consequence rather than collecting news headlines.

Use the 200 hours as a planning envelope, not proof of readiness:

Phase	Illustrative hours	Evidence you should produce
Coverage and mapping	90	Twelve concise chapter maps linked to the six official elements
Retrieval and technical consolidation	50	Flashcard/error records and closed-book explanations of weak topics
Applied written planning	45	Case-study issue maps, Section C outlines and completed professional-format answers
Timed review and correction	15	Timed section attempts, a recurring-error log and a final priority list

If you already know a topic, test it before reducing its hours. Familiarity from work can hide gaps in terminology, regulatory scope or the ability to explain a process clearly to an examiner.

Turn a previous attempt into a resit diagnosis

Because CISI recommends the final sitting mainly for resit candidates, repeating the same reading plan is a poor default. Diagnose the failed process before choosing more material.

1. Knowledge gap: you could not recall the product, process, regulation or control. Return to the relevant chapter, then retest it closed-book.
2. Selection gap: you knew the topic but chose weak or irrelevant points. Practise ranking issues against the command word and marks.
3. Application gap: you described theory without using scenario evidence. Require every developed point to cite a fact and explain its consequence.
4. Recommendation gap: your advice was generic or lacked ownership. Add action, owner, priority, evidence and monitoring.
5. Structure gap: the answer did not follow the requested report, memorandum or letter form. Build and time a reusable professional structure.
6. Timing gap: you left material unanswered or rushed the final section. Record actual minutes by section and practise outlines before full answers.

Do not infer an examiner’s reason that was never provided. Use your script memory, tutor feedback, practice evidence and recurring omissions to identify the most defensible explanation, then allocate study time to that weakness.

Practise management-level answers

The workbook explicitly asks candidates to think like a manager. Start with the requirement, select material evidence and explain why it matters. A reliable chain is: issue, evidence, consequence, control, recommendation and follow-up.

Show proportionate judgement. Not every weakness has the same urgency, and incomplete evidence should not be converted into certainty. State assumptions, identify what must be verified and use conditional recommendations where appropriate. For example, proceed only after access rights are segregated, a reconciliation break is resolved or a provider supplies independently selected evidence.

For longer answers, use headings that match the question rather than the order of your notes. End sections with a conclusion or action. This prevents technically correct material from becoming an unfocused list.

Stay aligned to the latest official syllabus

This guide was reviewed against the latest official syllabus located in 2026, Version 10, examinable from November 2025, together with the current withdrawal notice. Always verify the latest syllabus and candidate updates for your sitting; the official source for the date you plan to sit controls, even when a workbook remains useful.

The CISI GOM preparation page presents the six-element map, current three-section format and final-sitting notice. The completed learning hub adds 12 detailed chapter summaries, 140 flashcards, 152 rapid-reference and exam-trap entries, five written-answer planning sets and a syllabus-grounded AI tutor.

Final readiness check

Before treating the plan as complete, confirm that you can:

• explain the core processes from all six elements without relying on answer options;
• identify material issues and supporting evidence in an unfamiliar scenario;
• distinguish a symptom, immediate cause, root cause and control failure;
• write complete recommendations with ownership and follow-up;
• follow a report, memorandum or letter requirement visibly;
• select Section C questions by the full requirement rather than one familiar word;
• complete timed plans without sacrificing an entire section; and
• verify your eligibility, syllabus and final-sitting information with CISI.

A weak item is a study instruction. The checklist is useful only if it changes what you practise next.

Final takeaway

GOM rewards breadth, application and clear management communication. Confirm eligibility for the final sitting, map all six elements, practise the three sections differently and make every case-study point lead from evidence to operational action. That is a stronger preparation strategy than reading 200 hours without producing timed, reviewable answers.
