Flash BIA for Treasury in 3 Hours

What is a Flash BIA?

A Business Impact Analysis (BIA) is supposed to answer a simple question: what happens to the business if this process goes down? In practice, traditional BIA exercises take weeks, involve multiple consultants, and produce documents that sit on a shelf.

The Flash BIA for Treasury is a different approach. In three hours, with two to five people, you produce a Criticality Matrix that is directly actionable — ranking your Treasury processes by Maximum Tolerable Downtime and estimated financial exposure. No lengthy methodology. No bureaucracy.

The 4-step agenda

Step 1 — Identify Treasury Processes

Start by listing the processes that reflect Treasury's core operations. Cap the list at ten. More than that and the session loses focus.

Typical processes to consider:

• Supplier payments execution
• Payroll and salary transfers
• Cash forecasting and daily liquidity management
• Bank interface management (ERP ↔ TMS ↔ Bank)
• Payment approval workflows
• Short-term financing and credit line drawdowns
• Bank reconciliation
• Treasury reporting and compliance tasks

Step 2 — Define Maximum Tolerable Downtime

For each process, ask one question: “How long can this process be unavailable before it causes unacceptable consequences?”

Use a simple four-level scale:

The timing effect

MTD is not static. The same process can have very different tolerances depending on where you are in the month. Payroll due on the 15th has a 10-day tolerance on the 1st — and a sub-12-hour tolerance on the 14th.

The right approach: use a range-based MTD (for example, 0.5 to 14 days) and always use the lowest value when assigning criticality. You are sizing for the worst-case timing, not the average.

Step 3 — Estimate Financial Impact

You do not need a financial model. You need an order of magnitude per day of downtime. Three impact categories are sufficient:

Use simple thresholds

• Minor — less than €10K per day
• Moderate — €10K to €100K per day
• Major — €100K to €1M per day
• Critical — more than €1M per day

Step 4 — Classify and Summarize

Combine MTD and financial impact into a single Criticality Matrix. You can do this in Excel, on a whiteboard, or in a shared document. Assign one of four colors to each process:

• Critical — Immediate continuity required. No manual workaround is acceptable beyond a few hours.
• High — Needs a validated quick fallback plan. Manual workaround acceptable for less than 24 hours.
• Moderate — Monitoring or structured manual workaround sufficient for a few days.
• Low — Resilient by design or delay-tolerant. Standard recovery timeline acceptable.

Example output

How Long Does Disruption Last?

The MTD thresholds above only make sense in context. When sizing continuity requirements, it is critical to understand what you are actually preparing for — not a two-hour outage, but a major IT disruption lasting weeks.

Industry data consistently points to three to four weeks of average IT downtime following a serious ransomware incident:

• Statista: 24 days average business interruption after a ransomware attack
• Halcyon (2023 analysis): 22 days
• Veeam Ransomware Trends Report: 3.4 weeks (approximately 24 days)

The implication is direct: a process with an MTD of 12 hours needs a continuity solution, not a recovery plan. Waiting for IT to restore systems is not an option.

Practical Facilitation Tips

The Flash BIA works best as a focused, time-boxed workshop. Keep it practical:

• Duration: 3 hours maximum. Beyond that, consensus degrades and the session loses momentum.
• Participants: 2 to 5 Treasury leads — a mix of Treasury manager, ops, back-office, risk, and ideally one person from accounting or finance. No more than one representative per function.
• Format: Whiteboard or shared Excel on a screen. Facilitator reads each process, the team calls out MTD and impact estimates, facilitator records. No lengthy discussion on individual figures.
• Prioritize speed over precision: The value of the exercise is the ranked output, not the accuracy of each individual estimate. A ballpark that is completed is worth more than a precise analysis that never gets done.
