Creating Risk Registers

Learn how to create and maintain risk registers that give stakeholders a complete view of project and system risks in one place.

Individual risk blocks work well when documenting risks alongside related architecture content. But sometimes you need to see all risks together. A risk register collects related risks into a single view where stakeholders can assess the overall risk profile at a glance.

When to Use a Risk Register

Use a risk register when you need to:

Complete View
Present a complete risk view for a project, service, or domain
Track Over Time
Track risks with owners and mitigation status over time
Compliance
Support audit and compliance requirements
Review Meetings
Facilitate risk review meetings with a consistent format
Compare Risks
Compare risks by impact and likelihood

For individual risks discussed in context of specific architecture decisions, use the standalone risk block instead.

Adding a Risk Register Block

Risk Register Fields

Review Cadence

How often should this register be reviewed? Options include:

CadenceUse Case
WeeklyActive projects with rapidly changing risk profiles
MonthlyMost production services and ongoing initiatives
QuarterlyStable systems with infrequent changes
Ad-hocWhen significant changes occur

Risk Entries

Each entry in the register captures a single risk with its assessment and response. The fields match the standalone risk block:

Impact and Likelihood

Both use a three-level scale: Low, Medium, High. The combination determines the overall risk severity:

CombinationSeverity
High Impact + High LikelihoodCritical, requires immediate attention
High Impact + Low LikelihoodSignificant, needs contingency plans
Low Impact + High LikelihoodMonitor closely
Low Impact + Low LikelihoodAccept or address opportunistically

Category

Grouping risks by category helps identify patterns. Common categories include:

Status

Track where each risk stands:

This example uses the NeoArc Risk Register content block.

Organising Multiple Registers

Large organisations often maintain multiple risk registers. Common patterns include:

By Service or System
Each major system has its own register
By Domain
Payments, identity, logistics each have a register
By Project
Active projects track delivery risks
By Risk Type
Security risks, compliance risks consolidated separately

Choose an organisation that matches how your teams think about and manage risks.

Risk Register Reviews

A register is only useful if it stays current. Effective review practices include:

PracticeDescription
Scheduled reviewsCalendar the cadence and stick to it
Owner updatesRisk owners update their entries before the meeting
New risk identificationEach review includes time to identify new risks
Status progressionMove risks through statuses as circumstances change
Archive old risksRetired risks move to an archive section rather than deleting

Connecting to Architecture

Risk registers are most valuable when connected to the architecture they assess. Place registers in documentation pages that describe the relevant systems. When a risk entry mentions a component, link to that component's documentation.

This context helps readers understand both the risk and what it affects. A risk register floating in isolation loses much of its value.

Registers vs Individual Risks

Use both:

TypeUse Case
Risk registersComplete views, compliance needs, and governance reporting
Individual risk blocksDiscussing specific risks in the context of architecture decisions

The same risk might appear in both places. That duplication is acceptable when the contexts differ. A risk in an architecture decision page explains why something was designed a certain way. The same risk in a register helps track its status across all project risks.

The risk registers throughout this documentation site demonstrate how structured risk tracking integrates with architecture content.
