The assumptions behind the above connections can be surfaced by again reading the statements with a "because" clause added. [2]: 31 For example, Goldratt surfaces the following assumptions behind the 2nd statement in the example EC: In order to reduce setup cost per unit we must run large batches, because. setup cost is fixed and can't be reduced.
The scope constraint refers to what must be done to produce the project's end result. These three constraints are often competing constraints: increased scope typically means increased time and increased cost, a tight time constraint could mean increased costs and reduced scope, and a tight budget could mean increased time and reduced scope.
An issue log is usually blank at the beginning of the project, [2] but this is not always true for subsequent releases. In some projects, the issue log is actually used as a guideline for the release schedule; in that case the issue log can be populated with issues that are specifically tagged for completion in the upcoming release.
In order to meet these criteria, success factors/risks and constraints are fundamental. They define the: vision, objectives, scope and deliverables (i.e. what has to be achieved) stakeholders, roles and responsibilities (i.e. who will take part in it) resource, financial and quality plans (i.e. how it will be achieved)

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.
Statements of fact and assumptions that define the expectations of the system in terms of mission objectives, environment, constraints, and measures of effectiveness and suitability (MOE/MOS). The customers are those that perform the eight primary functions of systems engineering, with special emphasis on the operator as the key customer.
