Business impact analysis (BIA): how to run it

The BIA is the foundation of all continuity: it shows which processes are critical, what their downtime costs and how fast they must be restored. We break down the method and give a practical procedure.

What a BIA is and why you need it

A Business Impact Analysis (BIA) assesses how the stoppage of each process hits the company over time and in money. The BIA answers three questions: which processes are critical, what their downtime costs and how quickly they must be restored. Without a BIA, a continuity plan is built by guesswork.

Key metrics: RTO and RPO

  • RTO (Recovery Time Objective) — the maximum acceptable time to restore a process. "How fast the function must be back for losses to stay acceptable."
  • RPO (Recovery Point Objective) — the acceptable amount of data loss. "How much recent data can be lost without critical consequences."
  • MTPD — the maximum tolerable period of disruption, after which damage becomes irreversible.

How to run a BIA: the procedure

  1. List the processes (see the critical process register).
  2. Assess the impact of downtime for each process over time: after 1 hour, 1 day, a week — what is lost (revenue, fines, customers, reputation).
  3. Rank the processes by criticality.
  4. Set RTO and RPO for the critical processes.
  5. Identify recovery resources: people, IT, suppliers, sites.
Counting downtime in money: per ITIC (2024), an hour of downtime costs 90%+ of mid-sized and large companies more than 300,000 USD. A concrete figure for your process is the main argument for investing in protection. How to calculate it — in "What a day of downtime costs".

What comes next

BIA results feed the business continuity plan (BCP) and are a mandatory element of the ISO 22301 standard. Without a BIA you cannot set recovery priorities.

FAQ

How is a BIA different from a risk assessment?

A risk assessment answers "what can happen and how likely." A BIA answers "how painful it is if a process stops and how fast it must come back." In BCM they are used together.

What are RTO and RPO in plain language?

RTO is how fast to restore a process. RPO is how much data can be lost. The first is about time, the second about the data rollback point.

Can a small company run a BIA?

Yes. Take 3–5 key processes, assess the impact of their downtime over time and set target recovery times. This can be done in a single working day.

The assessment shows where business deadlines diverge from what technology can deliver. Those numbers are then produced either by your specialist or by us.
