Integrated modularisation and postponement strategies significantly enhance cost-effectiveness in mass customisation.

Why It Matters

This research provides a data-driven framework for optimising product and supply chain designs to meet individual needs without prohibitive costs. It highlights how strategic integration of these two approaches can unlock significant value for both providers and consumers.

Key Finding

The study found that while modular product design increases the variety of options available to patients, postponement in the supply chain reduces overall costs. Crucially, the combination of both strategies is essential for achieving the most cost-effective customisation.

Key Findings

• Product modularisation drives patient benefit through increased variety provision.
• Postponement strategies lead to cost reduction across the entire supply chain.
• Integrated application of both product modularisation and postponement is necessary for maximising cost-effective customisation.
• Computational simulations provide design requirements for reconfigurable product and supply chain systems in pharmaceuticals.

Research Evidence

Aim: To investigate the cost-benefit impact of integrating product modularisation and postponement strategies within pharmaceutical supply chains to enable cost-effective mass customisation.

Method: Computational simulation and modelling

Procedure: A holistic design framework was developed, adapting mass customisation strategies (product modularisation and postponement) for pharmaceutical products and supply chains. This framework was used to build a computational platform for simulating end-to-end supply chain scenarios based on real-life therapy and supply chain archetypes. Cost-effectiveness was assessed through these simulations.

Context: Pharmaceutical mass customisation and supply chain management

Design Principle

The synergistic integration of product modularity and supply chain postponement unlocks cost-effective mass customisation.

How to Apply

When designing products for markets requiring high levels of customisation, consider how product components can be standardised (modularisation) and how final assembly or configuration can be delayed until the last possible moment (postponement) to manage costs and inventory.

Limitations

The study's findings are based on simulations using specific therapy and supply chain archetypes, and real-world implementation may encounter additional complexities.

Student Guide (IB Design Technology)

Simple Explanation: To make custom products cheaply, you need to design them in standard parts that can be put together in many ways (modularisation) and delay the final customisation step until just before it's needed (postponement).

Why This Matters: This research shows how smart design and supply chain choices can make personalised products affordable, which is important for many design projects that aim to meet specific user needs.

Critical Thinking: How might the 'patient benefit' from product modularisation be quantified beyond simple variety provision, and what are the potential trade-offs in terms of complexity or usability?

IA-Ready Paragraph: This research by Siiskonen et al. (2023) highlights the critical role of integrating product modularisation and postponement strategies within supply chains to achieve cost-effective mass customisation. Their findings suggest that modular product design enhances variety for the end-user, while postponement significantly reduces operational costs. The study's computational modelling confirms that a combined approach is essential for maximising benefits, providing a strong rationale for adopting these integrated strategies in design projects aiming for personalised solutions.

Project Tips

• When designing a customisable product, think about which parts can be the same for everyone and which parts need to be unique.
• Consider how you can delay the final customisation step in your production or delivery process to save money and reduce waste.

How to Use in IA

• Reference this study when discussing strategies for mass customisation, product modularity, or supply chain optimisation in your design project.

Examiner Tips

• Demonstrate an understanding of how product architecture (modularity) and supply chain operations (postponement) interact to achieve business objectives like cost-effective customisation.
