[BCM] [KKH] [E1] [C5] Determining BC Assumptions

Determining BC Assumptions

 

Introduction

Business Continuity Management (BCM) planning is based on a series of informed assumptions about how the organisation is likely to operate during disruptive incidents.

Since it is impossible to predict every emergency or anticipate every operational challenge, organisations develop Business Continuity Plans (BCPs) using planning assumptions that establish the expected operating conditions during a crisis.

These assumptions provide the foundation for recovery strategies, resource planning, incident response, and decision-making.

Although ISO 22301:2019 does not prescribe a fixed list of business continuity assumptions, it requires organisations to understand their context, identify risks and opportunities, determine continuity requirements through Business Impact Analysis (BIA) and Risk Assessment (RA), and develop appropriate continuity strategies.

Establishing realistic planning assumptions supports these requirements by ensuring that recovery plans are practical, consistent, and capable of responding to severe but plausible disruption scenarios.

For KK Women's and Children's Hospital (KKH), BCM assumptions must reflect the operational realities of a highly specialised tertiary healthcare institution providing maternity, neonatal, paediatric, emergency, and women's health services.

During disruptions, KKH must continue to protect patients while managing uncertainty regarding staffing, infrastructure, technology, medical supplies, utilities, and external healthcare partners.

Well-defined assumptions help hospital management prepare for these uncertainties and improve the resilience of essential healthcare services.

This chapter presents the key planning assumptions that should underpin KKH's Business Continuity Management System (BCMS) and demonstrates how these assumptions influence continuity planning and organisational resilience.

 

Understanding BCM Assumptions

Business Continuity assumptions are statements describing conditions that are expected to exist during or immediately after a disruptive incident.

They provide a common planning basis when detailed information may not yet be available.

BCM assumptions help organisations:

• Develop realistic recovery strategies.
• Identify required resources.
• Prioritise recovery activities.
• Design effective Business Continuity Plans.
• Improve coordination between departments.
• Reduce uncertainty during emergencies.

Planning assumptions should always be reviewed periodically because organisational risks and operating environments evolve over time.

 

Example

KKH may assume that during a severe pandemic, patient demand for paediatric and maternity services will increase while staff availability decreases due to illness or caregiving responsibilities. This assumption influences workforce planning, cross-training, and contingency staffing arrangements.

 

Principles for Establishing BCM Assumptions

Planning assumptions should be:

Realistic

They should reflect credible disruption scenarios rather than unlikely extreme events.

Evidence-Based

Historical incidents, healthcare experience, national emergency planning, and organisational risk assessments should support assumptions.

Consistent

Assumptions should align with organisational policies, clinical governance, and operational procedures.

Flexible

Assumptions should allow adaptation as incident conditions evolve.

Periodically Reviewed

Changes in technology, healthcare delivery, infrastructure, regulations, or organisational strategy may require assumptions to be updated.

 

Operational Assumptions

 

Operational assumptions describe how hospital services are expected to function during disruptions.

Typical assumptions include:

• Critical healthcare services must continue operating.
• Elective procedures may be postponed to prioritise emergency care.
• Clinical priorities will be determined by patient safety.
• Recovery activities will be coordinated centrally.
• Some manual processes will replace unavailable automated systems.
• Recovery priorities will follow approved Business Impact Analysis results.

 

Example

If the hospital experiences a prolonged information system outage, clinicians may temporarily document patient care using approved paper-based downtime procedures until digital systems are restored.

 

Workforce Assumptions

Healthcare organisations depend heavily on skilled personnel.

Planning assumptions may include:

• Some staff may be unavailable during major disruptions.
• Staff may be required to perform multiple roles.
• Cross-trained personnel may support critical services.
• Additional working hours may be required during emergencies.
• Staff welfare remains a management priority.
• Specialist clinical expertise may have limited availability.

Example

During an infectious disease outbreak, KKH may assume that absenteeism among healthcare workers will increase due to illness, quarantine requirements, or family care responsibilities. Contingency staffing arrangements and cross-departmental support become essential.

 

Technology Assumptions

Modern healthcare delivery depends upon digital technology.

Assumptions may include:

• Clinical information systems may become temporarily unavailable.
• Network connectivity may be disrupted.
• Cybersecurity incidents may affect clinical operations.
• Some medical devices may require manual operation.
• Backup systems may require activation.
• Recovery will follow approved Disaster Recovery procedures.

 

Example

A ransomware attack affecting the Electronic Medical Record (EMR) system may require clinicians to use manual patient records while ICT teams restore systems from secure backups.

 

Infrastructure Assumptions

Hospital facilities and utilities are essential to healthcare delivery.

Planning assumptions include:

• Emergency generators will support critical infrastructure during power failures.
• Water supply interruptions may affect selected services.
• Air-conditioning failures may restrict use of operating theatres or specialised clinical areas.
• Medical gas systems must remain operational.
• Certain hospital buildings may become temporarily inaccessible.
• Facilities teams will prioritise restoration of critical clinical areas.

 

Supply Chain Assumptions

Healthcare services depend upon numerous external suppliers.

Assumptions include:

• Delivery delays may occur during regional emergencies.
• Critical medicines may become temporarily unavailable.
• Laboratory reagents may experience shortages.
• Medical consumables may require rationing.
• Alternative suppliers may need activation.
• Emergency procurement procedures may be implemented.

 

Example

Global disruptions affecting pharmaceutical manufacturing may delay deliveries of specialised neonatal medications. KKH should plan for alternative sourcing and maintain emergency stock levels for critical items.

 

Communications Assumptions

Effective communication is essential during emergencies.

Planning assumptions include:

• Standard communication systems may be disrupted.
• Alternative communication channels will be available.
• Staff require timely incident updates.
• Patients and caregivers expect accurate information.
• Media interest may increase significantly.
• Regulatory authorities require prompt notification of significant incidents.

Communication plans should include multiple channels, predefined responsibilities, and approved messaging processes.

 

External Environment Assumptions

External conditions may significantly affect hospital operations.

Examples include:

• National healthcare demand may increase rapidly.
• Community healthcare partners may also experience disruptions.
• Government emergency directives may change operational priorities.
• Public transport disruptions may affect workforce availability.
• Severe weather may restrict logistics and travel.
• Public concern may increase demand for information.

These assumptions assist KKH in preparing for events that originate outside the organisation.

 

Regulatory Assumptions

As a public healthcare institution operating in Singapore, KKH should assume that regulatory expectations continue to apply during disruptive events.

Examples include:

• Patient safety remains the highest priority.
• Clinical governance requirements remain applicable.
• Healthcare quality standards continue to apply.
• Data protection and confidentiality obligations remain in force.
• Significant incidents may require reporting to relevant authorities.
• Continuity arrangements should support national healthcare resilience.

These assumptions reinforce the need to integrate BCM with governance, risk management, and compliance activities.

 

Clinical Assumptions

Clinical continuity planning requires several specialised assumptions.

Examples include:

• Emergency maternity services cannot be suspended.
• Neonatal Intensive Care Unit (NICU) services must remain operational.
• Children's Emergency Department must continue accepting urgent cases.
• Intensive Care Units require uninterrupted utilities.
• Emergency surgeries cannot be delayed beyond clinically acceptable limits.
• Diagnostic support services remain essential to patient care.

These assumptions guide the prioritisation of recovery activities during major disruptions.

 

Financial Assumptions

Financial planning assumptions support resource allocation during incidents.

Examples include:

• Emergency expenditure approval processes may be accelerated.
• Contingency budgets may be activated.
• Procurement procedures may be simplified during emergencies.
• Insurance coverage may support selected recovery costs.
• Financial reporting continues throughout prolonged disruptions.

 

Reviewing BCM Assumptions

Planning assumptions should be reviewed regularly.

Review triggers include:

• Annual BCM programme reviews.
• Business Impact Analysis updates.
• Risk Assessment reviews.
• Major incidents.
• Healthcare policy changes.
• Organisational restructuring.
• New technologies.
• Changes in healthcare delivery models.
• Lessons learned from exercises.

Regular reviews ensure assumptions remain realistic and aligned with KKH's operating environment.

Practical Example

Consider a widespread regional haze event that significantly reduces air quality across Singapore while increasing paediatric respiratory admissions.

KKH's BCM assumptions would include increased demand for emergency and inpatient paediatric services, reduced staff availability due to health concerns, higher consumption of respiratory medications and oxygen supplies, and the need for enhanced indoor air quality management within clinical areas.

The hospital may also assume that some elective outpatient appointments will be rescheduled to release clinical capacity for urgent cases.

Because these assumptions have been established in advance, KKH can activate predefined response measures such as redeploying clinical staff, increasing pharmacy stock levels, coordinating with suppliers, enhancing communication with patients and caregivers, and monitoring hospital capacity.

These actions enable the hospital to respond consistently and efficiently while maintaining continuity of essential healthcare services.

 

Business Continuity Management assumptions provide the planning foundation upon which effective continuity strategies and recovery plans are built.

By identifying realistic assumptions relating to operations, workforce, technology, infrastructure, supply chains, communications, regulatory obligations, and clinical priorities, KK Women's and Children's Hospital can prepare for a wide range of disruptive events while reducing uncertainty during incident response.

These assumptions enable hospital management to develop practical recovery arrangements that reflect the unique operational requirements of a specialist tertiary healthcare institution.

The planning assumptions established in this chapter will support the remaining stages of the ISO 22301 Business Continuity Management lifecycle.

They will inform the Business Impact Analysis, Risk Assessment, Business Continuity Strategy development, and Business Continuity Plan preparation described in subsequent chapters.

Through regular review and refinement, KKH can ensure that these assumptions remain relevant as healthcare delivery, technology, organisational priorities, and the external operating environment continue to evolve, thereby strengthening the hospital's overall resilience and its ability to provide uninterrupted care to women, newborns, children, and families across Singapore.
