Continuity planning sounds like something large companies do. In practice it is one short document answering a simple question: if the thing you rely on stops, what happens next?

For a small business that document is worth an afternoon and it is the difference between a bad week and a closure.

List what would actually stop you

Not disasters in the abstract. The specific things: the premises being unusable, power being out for longer than your backup lasts, the one person who knows how something works being unavailable, a key supplier failing, your systems or data being lost, a vehicle off the road.

Rank them by how likely they are and how much they would hurt. Most small businesses find two or three items sit far above the rest, and those are the only ones worth planning for in detail.

For each one, answer three questions

  • How long can we survive it? Hours, days, weeks. This sets how much you should spend preventing it.
  • What is the workaround? A second supplier, a generator, working from somewhere else, a colleague who has been shown how.
  • Who decides and who tells people? Named, not "management".

The two most common gaps

One person who knows something. The person who does the invoicing, or knows the supplier relationship, or has the passwords. Write it down and show somebody else — not because they will leave, but because they will at some point be unreachable for a week.

Backups nobody has tested. A backup that has never been restored is a belief, not a backup. Restore something from it, once, and find out. This is where businesses discover the backup stopped running months ago.

Keep the contact list somewhere reachable

Staff, key customers, key suppliers, insurers, landlord, bank, IT. On paper as well as in a phone, because the scenario where you need it is frequently the one where you cannot get into the building or the systems.

Tell customers early

When something goes wrong, the businesses that keep their customers are the ones that say so quickly and say what happens next. Silence is read as incompetence, and a customer who finds out by being let down makes other arrangements.

A short honest message on the day beats a detailed explanation a week later.

Review it when something changes

New premises, new key supplier, new system, a person leaving. The plan is only useful if it describes the business as it currently is, and a document written two years ago about an operation that has since changed is worse than none — it produces false confidence.
