Proof of concept for a decision engine: scope, success test and exit

What is a proof of concept for a decision engine?

A proof of concept tests one narrow claim on one case: the engine can read your kind of decision and return a result your team can check. It is smaller than a live rollout and quicker than a full evaluation. The output is a yes, a no, or a list of changes, recorded in writing with the effort it took.

Keep the claim concrete. Examples include ’the engine returns a score and 3 priority risks for a hub choice’ or ’a reviewer can replay the verdict from the inputs’. A claim that a reader can verify in an afternoon makes a good proof of concept, and a broad claim such as ’the engine is useful’ belongs to a later pilot.

How does a proof of concept differ from a pilot of a decision engine?

A proof of concept looks backward or sideways: it uses a past case or a sample case whose answer you already know, so the team can compare the engine’s output with a known outcome. A pilot looks forward: it runs on a live decision with a deadline and an owner. The first checks capability, and the second checks value.

Run them in order when the stakes are high. The proof of concept takes days and carries a small fee, and a pilot follows when the first result is positive. Both share the same habit: write the test before the work starts, and keep the record.

How do you scope a proof of concept for a decision engine?

Scope has 5 items: the case, the question, the data list, the owner and the dates. Choose a case with a known outcome, for example a contract you signed last year, and write the question as it stood on the day you decided. List the documents the engine needs and name one person who answers provider questions.

Cap the scope in size and in time. One case, one question, and a date for the result are enough. The EQOS Asia pricing page offers examples of questions that fit: whether to sign a contract, whether to partner up, whether to hire a key executive (EQOS Asia pricing page, as of October 2026). Share the written scope with everyone who attends the review.

What success test should a proof of concept for a decision engine pass?

Write the test before the run. Three checks cover most cases: the engine accepts your inputs, the output names a score, a recommendation and the main risks, and a second run on the same inputs returns the same result. Each check has a yes or a no, so the review takes minutes and the outcome is clear.

Add one comparison. Set the engine’s recommendation beside the decision your team took and the outcome that followed. Where they agree, you gain evidence of fit; where they differ, you learn which assumption to review. A φ(S) score below 0.618 falls in the STOP zone, and a score above it falls in the OK zone (EQOS Asia method page, as of October 2026), which gives the comparison a shared scale.

Which EQOS Asia tier suits a proof of concept for a decision engine?

Two entry tiers fit a narrow proof of concept. A Reading at US$358 is delivered in 24-48 hours and runs one question through the audit on 9 dimensions. A Decision at US$910 is delivered in 48-72 hours and models one structural choice from your documents (EQOS Asia pricing page, as of October 2026). The Study at US$1,369 adds modelling and prediction when the claim needs them.

Start with the free 30-minute pre-diagnostic, held by video in Singapore time (SGT, UTC+8), to pick the tier for your claim (EQOS Asia contact page, as of October 2026). The Λ simulator shows the format of the output beforehand, so the success test can name the fields you expect to see.

Which exit rules end a decision engine proof of concept cleanly?

Agree three outcomes in advance: stop, extend or move to a pilot. State which result of the success test leads to each. Stop when a check fails for a reason that the inputs you hold cannot fix. Extend when one check needs a better input. Move to a pilot when all checks pass and the comparison shows fit.

Agree what happens to the data. Under the EQOS Asia NDA, the receiving party returns or destroys confidential information within 10 business days of a written request, and confirms it in writing (EQOS Asia NDA page, as of October 2026). Put that date in your exit rules, and keep a copy of the accepted terms with the project file.

What record should a decision engine proof of concept leave behind?

Write one page at the end: the claim, the case, the checks with a yes or a no, the effort in hours, the cost, and the decision to stop, extend or move on. Date it and name the reviewer. A one-page record lets a colleague who missed the work understand the result in two minutes.

File the record with your build or buy sheet and your selection checklist, so that each later test starts from evidence. Repeating the same format across several engines allows a fair comparison, because each one faced the same claim, the same case and the same checks. The record also shows the team how its own judgment compared.
