=== Implicit and explicit assumptions ===

Explicit assumptions are assumptions of which the intention that is fully revealed or expressed without vagueness, implication, or ambiguity. However, explicit statementsambiguity—though in a plan, they often haverely hiddenon implicit assumptions. Implicit assumptions are assumptions that are not expressed and may go undetected. If implicit assumptions prove to beare wrong, this can damage projects.

The steps of Assumption-Based Planning (ABP) are:

* Identify assumptions: Collect all assumptions implicit, explicit, primary and derivative, out of the (business) plan.

* Determine criticality: Try to quantify the assumptions as much as possible in order to determine which assumptions have the greatest (financial) impact.

* Design tests: Design a test for every critical assumption. In a test design you state how to test the assumption and what proves the assumption wrong or right.

* Schedule tests: Every critical assumption needs tomust be tested, but not all assumptions can be tested in the present. So future assumptions tests are scheduled in a test schedule. Some possible reasons to schedule a test in the future are a lack of information in the present or a dependency on the test outcomes of other tests.

* Test assumptions: When an assumption is tested this results in a test outcome, which proves the assumption right or wrong.

* Reassess plan: Based on the test outcomes and the test schedule one might decide to reassess the venture plan and update the business plan with the new insights gathered in the ABP process.

* Plan re-testing: The assumptions need tomust be re-tested regularly if not constantly. There should be a retest schedule offor every critical assumption.

* Create or update the assumption plan: The assumption plan holds all data gathered during the ABP process.

During this step the assumptions are identified and there is a determination of criticality. The hardest part of CAP is to identify the assumptions that are not written down.

In order toTo determine the criticality of the assumptions, they need tomust be quantified;. itThis ismakes thenit possible to put the financial results in a [[spreadsheet]] and link them together. These financial impacts will change for the various assumptions.

CAP measures the criticality of an assumption as a change in the [[net present value]] of a venture (NPV). To determine criticality each assumption is assigned a range of uncertainty: base case, best and worst case. Then, assumption for assumption, while keeping the other assumptions at [[ceteris paribus|base case]], the NPV changes for each assumption in the worst- and best-case scenarios are checked.

===Test program design===

The assumptions need tomust be tested. Sometimes good market research is enough,

other times a working prototype needs tomust be developed. The testing order in which thefor assumptions are tested is critical in terms of testing cost. A major focuse of the moneyCAP method is to maximize the learning per unit spentexpenditure on testing. One

of the major focuses of the CAP method is to maximize the learning per unit expenditure on testing.

In order toTo determine the best testing option, the test Effectiveness ratio (e)

is calculated for one or more assumptions based on the estimated Costs (C), Time spend on testing (T) and the estimated reduction (R) between the NPV values of the assumptions (P as a percentage of the NPV range). Using these parameters, the effectiveness ratio (e) is calculated:

===Funding request===

When the test program design is ready and the costs are clear, resources have tomust be allocated to the test program. In most companies or start-ups clearance from senior managers or [[venture capitalists]] is needed to conduct the tests.

===Test implementation===

===Venture Reassessment===

When the results of one or more tests are known, it might be that resources need tomust be re-allocated and business plans have to be updated.
