Correct Answer: gesture from a previous or similar project
analogous cost estimating is a method used in project management for estimating various project parameters such as cost, scope, budget, and duration based on historical data and experience from previous similar projects. this technique is particularly useful in the early stages of a project when detailed information is limited. it involves comparing the current project to past projects that are similar in nature and adjusting for any known differences to arrive at an estimate.
when employing analogous cost estimating, project managers look at measures of scale such as the size, weight, and complexity of previous projects. these measures help in making informed guesses about the likely costs or efforts required for new projects. for instance, if a previous construction project involved building a 10-story building at a certain cost, a similar future project might be estimated based on this cost, adjusted for any differences in location, materials, or economic conditions.
the options listed in the question — size, gesture, weight, and complexity from a previous or similar project — are potential measures of scale that could be used for analogous estimating. however, not all these measures are typically relevant or applicable:
- **size** and **weight** are quantitative measures and can be directly correlated with costs. for example, larger or heavier projects might require more materials and labor, thus increasing the costs.
- **complexity** relates to the intricacies involved in a project which might affect duration, the need for specialized skills, and ultimately, the cost. more complex projects generally require more sophisticated management and might incur higher costs.
- **gesture**, however, is not a standard measure of scale in project management and cost estimating. gestures could refer to non-quantifiable aspects like style or approach, which are subjective and do not directly correlate with the scope, cost, budget, or duration in a measurable way that analogous estimating requires.
therefore, among the options given, "gesture from a previous or similar project" is the one that does not fit with the standard approach to analogous cost estimating. analogous estimating relies on measurable, quantifiable data from past projects to estimate parameters for new projects, and "gesture" does not provide a quantifiable measure that could be used effectively in this context.
