[P3] Impact Over Time of Business Functions

Management Report for Impact Over Time of Business Functions

This section outlines the methodology for assessing the "impact over time" of the eight Critical Business Functions (CBFs) within Bandtree.

Rather than evaluating disruptions as a static event, this approach recognises that the severity of impact often escalates the longer a function remains inoperative.

The Impact Over Time framework provides a structured view of how critical operations degrade over predefined time intervals, ranging from the initial 4 hours to 60 days.

Using a standardised impact rating scale from 1 (minimal impact) to 5 (catastrophic impact), each business function is assessed in terms of its consequences on operational continuity, financial performance, legal obligations, reputational standing, and health and safety.

This time-based impact assessment enables organisations to:

Prioritise recovery activities and allocate resources appropriately.
Determine accurate Recovery Time Objectives (RTO) and Maximum Tolerable Periods of Disruption (MTPD).
Identify vulnerable periods that could compound the effects of a disruption.

By integrating this analysis into the broader Business Continuity Management (BCM) process, organisations such as Bandtree can better ensure the resilience of operations and infrastructure across various functions and sub-functions.

Key Notes

RTO (Recovery Time Objective): Indicates the acceptable downtime before severe impact begins.
MTPD (Maximum Tolerable Period of Disruption): Maximum allowable time the sub-function can be disrupted before irrecoverable consequences occur.
Vulnerable Period: Timeframes in which disruption has amplified effects (e.g., audits, contract renewals, public reporting).

Summing Up ...

The Impact Over Time analysis provides a powerful lens for viewing the dynamic effects of business disruptions.

By mapping out how the severity of impact escalates across specific timeframes, organisations can gain actionable insights to support continuity planning, resource allocation, and risk mitigation strategies.

This structured assessment helps define realistic recovery priorities and enhances communication across departments and stakeholders.

When paired with clearly defined RTOs and MTPDs, it serves as a cornerstone for resilient and informed decision-making during crises.

Ultimately, understanding the time-sensitive nature of operational impacts empowers organisations like Bandtree to maintain service excellence, meet stakeholder expectations, and fulfil their mandates—even in the face of unforeseen disruptions.
