[Column] The Necessity of "Design Engineering" and Specific Approaches to Implement It

[Column] The Necessity of "Design Engineering" and Specific Approaches to Implement It

Why is "design engineering" necessary? An explanation of its necessity for solving corporate challenges and specific approaches to implementation.

In the first session, "Design Engineering that Brings Joy to the Future of Companies, Developers, and Users," we discussed how developers can create value and deliver it to users in the form of services and products, as well as the usefulness and overview of "Design Engineering" as a means to solve corporate challenges such as promoting digital transformation (DX). In the second session, we will introduce a more specific flow of collaboration between designers and engineers, explaining why this methodology is desirable and deepening the understanding of its necessity. *For detailed content of the column, please refer to the related links or download the PDF. If you have any questions or concerns, please feel free to contact us.*

[Column] Means of "Realization" Necessary for Design Engineering

[Column] Means of "Realization" Necessary for Design Engineering

In the 5th session, we will focus on the means to "realize" ideas and explain sdtech's approach to design engineering!

In the previous fourth session [“Ideas” necessary for design engineering], we explained design engineering as a means to discover “what to conceive and how to realize it” as the original upstream process of design and development. This time, we will introduce “how to realize it.” Recently, in application development required for products and services, by utilizing various tools and services, the process of prototyping what has been defined in requirements and design, and evaluating the validity of the incorporated requirements has become more efficient, although it cannot be said to be “easy.” By advancing digitization within the development team, efficiency has been improved. It is important not to eliminate the “ideas” generated in the previous process merely as theoretical discussions but to make them tangible. This allows for the identification of areas for improvement and better requirements during the concretization process, and it also enables prioritization towards “realization.” *For detailed content of the column, please refer to the related links or download the PDF. If you have any questions or concerns, please feel free to contact us.
