“…Initially, one must consider two of the major issues that surround the design process, it is both complex and uncertain. The design process is inherently uncertain (Chalupnik et al, 2009;Dong et al, 2014;Eckert and Clarkson, 2010;Pich et al, 2002); a form of unpredictable problem-solving (Jonassen, 2000) and it is therefore critical that one appreciates the influence uncertainty has over the design process. It is only by doing so, that one can plan product deigns projects, which includes estimating their design effort needs.…”

The quick and accurate estimation of design effort can be make or break for all but the largest of product design consultancies. Traditional design project planning see designers being taken away from the metaphorical drawing board to spend time assessing project briefs and estimating workloads. Typically these designers base these estimates on their tacit knowledge and experience, and for the most part, they are accurate. However, this is time-consuming and therefore (indirectly) costly, as time spent planning, is not time spent designing. Many more sophisticated approaches for estimating design effort have been developed, but many require large bodies of past data and sophisticated analysis, such as artificial neural networks; and others have highly-specific use cases.This paper proposes a new method to develop a design effort estimation tool for product design consultancies. This method captures the tacit knowledge and experience of design team members and the tool replicates it quickly and effectively; graphically modelling factors that influence design effort needs in product design projects.

“…This is, in part, due to companies not analysing the cause of such problems in the planning process, leading to the resentment and blame of the project manager for a plan's lack of success (Eckert and Clarkson, 2010). It is clear that no two design projects the same, and also that the design process itself is inherently uncertain (Dong et al, 2014;Eckert and Clarkson, 2010;Pich et al, 2002), therefore the challenge in estimating design effort to complete a project is a particularly difficult one (Salam and Bhuiyan, 2016).…”

Design effort, the amount of time required to complete a project or task (Salam et al., 2009; Salam and Bhuiyan, 2016), is a required resource for any design project which can be influenced by a number of factors. Estimating design effort is a significant challenge that can be mitigated through an understanding of these influential factors. This understanding is held as tacit knowledge by experts, earned through experience; yet, although these factors vary in type and impact, understanding their details can provide insight and improve future estimations. Some previous methods to estimate design effort identify these factors, either from: expert opinion, or historical data analysis with each approach has advantages and disadvantages.This paper is comprised of three parts:A review of published methods and tools for estimating product design effort and whether they consider and identify influential factors; an analysis of possible trends in the identification of factors influencing product design project length; and a new method for identifying the influential factors of product design project length.

Any engineering design project faces various types of uncertainties. They cause risk that a project goal cannot be accomplished within lead time. A design project manager should identify potential risk factors and causal relations among them in a project. Although it is worthwhile to spend much time on a workshop for project members to understand unnoticed risks, it is often a hard job to identify risk factors and causal relations in a mutually exclusive and collectively exhaustive way. This paper proposes a risk identification method based on a framework schematizing a fundamental model of a risk chain mechanism in an engineering design project in order to support a project manager and project members to systematically identify potential risk factors and causal relations among them. A proposed method provides categories of typical risk factors in an engineering design project. A typical chain mechanism among those categories is also defined. Those elements in a fundamental model can facilitate a project manager and project members to find unnoticed factors in a project. A case study of a risk workshop for a student formula car design project is demonstrated to show that the proposed method facilitates project members to understand potential risk factors and to build a comprehensive risk chain model. 1.
