Proposed framework for estimating effort in design projects

Purpose: The purpose of this paper is to propose a framework to assist in the estimation of effort for projects in the field of design. The study first seeks supporting material to outline an understanding of how design professionals have access to time estimation information for quoting their projects. Design/methodology/approach: The work was based on in-depth interviews conducted with 13 professionals from various design sectors that focused on understanding important elements of the project quotation process. Content analysis was performed on the information provided, and four dimensions were identified. A framework that included these dimensions was designed and validated using a focus group composed of professionals involved in project quotation. The framework includes the generation of a project network structure; identifying tasks and their duration for each design activity; and the ways in which this information remains updated and evolves through the incorporation of dynamic systems concepts. Findings: The results of this study will be the production of an external knowledge base that designers can use as a basis for performing their profession. Originality/value: This study is relevant because there is no information source that addresses tasks and associated durations on which design professionals can rely for the development of quotations.
