Concurrent Engineering: What It Is, How It Works and Its Benefits

Concurrent engineering, also known as simultaneous engineering, is a multidisciplinary approach in which several design and development activities are carried out in parallel and in a coordinated way. It brings different functions together from the early stages of a project, such as engineering, design and production, with the aim of improving collaboration, shortening development cycles and identifying potential issues earlier.

Unlike a strictly sequential process, concurrent engineering allows different disciplines to work at the same time on shared information. This approach can help reduce design errors, limit rework and improve consistency across the different stages of product or project development.

Digital tools such as CAD software, PLM and PDM systems, and collaborative platforms can support this way of working by making information easier to share and changes easier to coordinate.

Concurrent engineering vs sequential engineering: what is the difference?

The main difference between concurrent and sequential engineering lies in how design and development activities are organized. In a sequential, or waterfall, approach, each phase follows the previous one in a linear order: design, production preparation and testing are completed one after another. This provides a clear structure, but changes or issues identified late in the process may require teams to revisit work that has already been completed.

Concurrent engineering uses a more integrated and parallel approach. Multiple activities can progress at the same time, and teams collaborate from the early stages of the project. This supports more continuous communication between engineering, design and production, helps identify issues earlier and reduces the number of handoffs between disciplines.

The following sections look at the main benefits of concurrent engineering and how this approach can improve collaboration between disciplines.

Main benefits of concurrent engineering

Concurrent engineering is based on teamwork and collaboration between different functions involved in developing products, services and processes. When information is shared promptly and decisions are coordinated across disciplines, teams can address issues earlier and reduce the risk of rework later in the project. Key benefits include:

• Reduced time and cost. When more activities can move forward in parallel, overall development time can decrease. Identifying and correcting issues earlier can also limit revisions and rework in later stages.
• Better project quality and consistency. Continuous collaboration helps teams consider the requirements of different disciplines from the beginning and reduce inconsistencies between design, production and verification.
• More efficient processes. Integrating design, production and other functions helps information flow more smoothly and improves operational coordination and issue management.
• Greater consistency across disciplines. When teams work with shared and up-to-date data, the risk of one discipline using information that is not aligned with the others is reduced.

How does the concurrent engineering process work?

Concurrent engineering does not remove the normal stages of a project. It changes how they are coordinated. Activities that would traditionally be carried out one after another can overlap and exchange information during development. While requirements are being defined, teams can already begin assessing design solutions, materials, costs and production constraints.

Design, prototyping, verification and production planning can therefore proceed partly in parallel. Test and verification results can feed directly into design changes, while production and supply-chain teams can contribute constraints and recommendations before the design is fully frozen.

Later activities such as industrialization, launch and support can also generate feedback that informs the project. Concurrent engineering therefore creates a more continuous flow between activities, based on shared information and coordination across disciplines.

Concurrent engineering examples

Concurrent engineering can be applied in different contexts, from product development and manufacturing to industrial plant design.

• Product development: design, manufacturing and supply-chain teams work on the same product at the same time, reviewing technical requirements, cost and feasibility from the early stages.
• Automotive and machinery: designers and production teams collaborate during development to evaluate components, manufacturing processes and assembly constraints before final release.
• Industrial plant design: process, piping, 3D plant design and electrical disciplines can work with coordinated information without necessarily waiting for one discipline to be fully completed before the next one starts.

Concurrent engineering in industrial plant design

In industrial plant design, concurrent engineering can help coordinate disciplines such as process engineering, piping, 3D plant design and electrical design. In this context, ESAPRO supports an integrated multidisciplinary workflow by connecting activities and data that belong to different stages and disciplines of plant design.

In a strictly sequential workflow, for example, the 3D model may only be developed after the P&ID has been completed and information has been handed over to the piping discipline. In a more integrated approach, process data, line specifications and project information can be shared and checked while the work is progressing. With ESAPRO, information defined in the P&ID can be transferred to the 3D model and checked through matching functions, supporting data continuity and consistency.

This can help teams identify inconsistencies earlier and reduce the need to re-enter the same information manually in different tools.

Which software and tools support concurrent engineering?

There is no single “concurrent engineering software”. The approach is supported by tools that make collaboration between disciplines, data sharing and coordinated change management easier.

These can include CAD software, PLM and PDM systems, collaborative platforms and specialist engineering applications that connect different stages of design. In plant design, ESAPRO supports concurrent engineering principles through an integrated environment for process design, 3D piping and electrical design.

For industrial plant engineering, continuity between P&IDs, process data and the 3D model is particularly important. Reducing manual data re-entry and keeping information consistent across disciplines makes the workflow more aligned with concurrent engineering principles.

An integrated workflow for plant design

ESAPRO supports an integrated workflow between process design and 3D plant modelling through P&ID data management, piping classes and structured transfer of information to the model. Bidirectional matching can also be used to compare information in the P&ID and the 3D model and identify possible inconsistencies. The suite also includes tools for electrical design, supporting a multidisciplinary approach to industrial plant projects.

This allows different disciplines to work with more consistent and shared information while reducing manual handoffs between project phases. Rather than being a generic concurrent engineering platform, ESAPRO is a plant design solution whose integrated workflow supports the practical principles of concurrent engineering.
