Human Centricity in Integrated Design Engineering

Abstract

Integrated Design Engineering is a holistic approach to create products of any kind. These are created in a human-centred way, as interests, issues, and needs of people involved in any product life cycle phase are respected. Attributes that don't fix realisation issues describe neutrally the required product performance. They result from needs, desires, expectations, and conditions in relation to the capabilities of users and from the environments where the product is created and to be used. Requirements to assure human centricity add to the requirements to realise the expected performance.

Assessment of empowerment via inclusion of people in product lifecycle processes

“…The reasons for imbalanced development can be various; our approach to limiting the context starts with the definition of the lifecycle of a product. As proposed by Urakami et al (2018), the product lifecycle has five phases: planning, development, production, utilisation and recirculation. We use these phases in our framework to define the context for empowerment assessment.…”

“…We accepted internal stakeholders as manager, coordinator, and project, production and sales teams. We grouped the customers into the following: resource, co-creator, evaluator, buyer and user (Nambisan 2002;Urakami et al 2018) without considering the number of people in each group.…”

Toward a Comprehensive Definition of the Non-User

“…Most established literature in product development includes the user (Ehrlenspiel et al, 2007;Feldhusen and Grote, 2013;Lindemann, 2007) and several stakeholders (Feldhusen and Grote, 2013;Vajna, 2014;Urakami and Vajna, 2018), but a clear definition of non-users is missing. Figure 1 describes all parties involved in the development process according to Integrated Design Engineering following Vajna (2014), starting with providers such as the product developer, manufacturer, supplier or distributor.…”

Achieving Simplicity: A Consideration of a Systematic Approach

“…From the provider's point of view, both the producibility and the cost-effectiveness of the product is in the focus (Vajna, 2014). It can be concluded from this investigation that different approaches are pursued in achieving simplicity within the product life cycle (according to Urakami and Vajna, 2018), especially in distinguishing between the development process, i.e. the consideration of the provider (which covers developer, manufacturer, manager, salesperson etc.)…”
