Scientific Reports · 2026

Key Findings

01MODT can quantify obsolescence potential at both product and component levels.
02Design aspects like reparability and material availability significantly influence multiple obsolescence types.
03Early identification of obsolescence risks enables proactive interventions in design and supply chain strategies.
04The tool supports after-sales service planning, cost management, and spare part provisioning.

Application

Design takeaway

Integrate a multi-dimensional obsolescence assessment framework, like MODT, into the early design stages to proactively address lifecycle risks and enhance product sustainability.

How to apply

When designing new products or redesigning existing ones, use a structured approach to evaluate potential technological, functional, psychological, economic, planned, and supply chain obsolescence risks. Assign scores to relevant design attributes and weight their impact to identify critical areas for intervention.

Project actions

01When evaluating your design, think about how easily it could become obsolete due to new technology, changing user needs, or supply issues.
02Consider creating a scoring system for different aspects of your design that might lead to obsolescence, and then weigh which factors are most important.

Method & Evidence

AimTo develop and validate a structured, scalable methodology for evaluating a product’s susceptibility to various types of obsolescence from the early design stages.

MethodDevelopment and application of a quantitative diagnostic tool (MODT) involving design attribute scoring and impact weighting.

ProcedureThe Multi-Obsolescence Diagnostic Tool (MODT) was developed to assess six types of obsolescence (technological, functional, psychological, economic, planned, diminishing manufacturing sources/material shortages) at product and component levels. This involved assigning scores to design attributes and applying impact weights. The tool was then applied to a case study of an electromechanical drill.

ContextSustainable manufacturing and product lifecycle management.

Variables

IVDesign attributes and their impact weighting.

DVProduct susceptibility to different types of obsolescence (quantified).

CVSpecific product category (e.g., electromechanical drill), types of obsolescence considered.

Strengths & Limitations

Strengths

+Provides a structured and quantitative approach to obsolescence management.
+Addresses multiple dimensions of obsolescence, offering a holistic view.
+Applicable at both product and component levels.

Limitations

It can be challenging to accurately predict future technological advancements or market shifts that could cause obsolescence.

Reliability & validity

The reliability of MODT would depend on consistent application of scoring and weighting criteria. Validity is supported by its ability to identify known obsolescence drivers in case studies and its alignment with principles of sustainable design and lifecycle management.

Think critically

How can the MODT framework be adapted to assess the obsolescence risks of digital products or software, where obsolescence might manifest differently than in physical goods?

Design Principles

"Proactive obsolescence management through integrated design diagnostics is essential for sustainable product lifecycles."

By integrating obsolescence diagnostics into the design phase, manufacturers can mitigate risks associated with technological, functional, psychological, economic, planned, and supply chain issues. This foresight allows for informed decisions regarding material selection, modularity, and supply chain strategies, ultimately reducing waste and improving overall system performance.

What This Means for Your Design

A special checklist called MODT helps designers figure out early on if a product might become outdated or hard to fix later, so they can design it better from the start to last longer and be more eco-friendly.

How to use in your project

1.Reference the MODT framework as a method for evaluating the long-term viability and sustainability of your design solution.
2.Use the principles of MODT to justify design choices aimed at extending product lifespan and reducing environmental impact.
