Explicitly incorporating user experience (UX) design principles and practices into software product line engineering leads to more consistent and effective user interfaces across a range of related products. This user-centred design research insight is drawn from a 2019 study published in Proceedings of the ... Annual Hawaii International Conference on System Sciences/Proceedings of the Annual Hawaii International Conference on System Sciences. Using Multiple-case study research, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Adopt a systematic approach to user experience design that is integrated into the core processes of software product line engineering, rather than treating it as an add-on.

Key Findings

01Software product line engineering has historically neglected user experience design.
02There is a need for explicit best practices to integrate UX into product line development.
03The study identified initial practices and challenges in UX integration within two specific product lines.

Application

Design takeaway

Adopt a systematic approach to user experience design that is integrated into the core processes of software product line engineering, rather than treating it as an add-on.

How to apply

When developing a suite of related software products, establish a dedicated UX strategy and framework that guides the design of each product to ensure a unified user experience.

Project actions

01Consider how your design choices will impact multiple related products or variations.
02Document user experience guidelines that can be applied across your design project.

Method & Evidence

AimWhat are the industry best practices for integrating user experience design into software product line engineering?

MethodMultiple-case study research

ProcedureThe researchers conducted a preliminary exploratory study within two distinct product lines at Siemens AG (healthcare software and industrial automation software) to identify and document current practices and challenges related to UX design in product line development.

ContextSoftware product line engineering, specifically within the healthcare and industrial automation sectors.

Variables

IVIntegration of UX design practices into software product line engineering.

DVUser experience quality, design consistency across products.

CVSpecific product line context (e.g., healthcare vs. industrial automation software).

Strengths & Limitations

Strengths

+Addresses a gap in existing research by focusing on UX in product lines.
+Uses a real-world industry context (Siemens AG) for the case study.

Limitations

The study was limited to specific industries (healthcare and industrial automation) and a single company, so the findings might not apply to all types of software product lines.

Reliability & validity

The validity of the findings relies on the depth of the case study analysis and the accurate representation of industry practices. Reliability could be improved with more extensive case studies across different companies and product types.

Think critically

How can the principles of user experience design be effectively scaled and managed across a large and diverse software product line to maintain both consistency and adaptability?

Design Principles

"User experience consistency is a critical factor for success in software product line development."

Software product lines, which aim to develop a family of similar products efficiently, often overlook the crucial aspect of user experience. This research highlights that a systematic approach to UX design within these lines can prevent fragmented user journeys and ensure a cohesive brand identity, ultimately leading to higher user satisfaction and adoption rates.

What This Means for Your Design

When you make a family of similar software products, you need to think about how people will use them all together, not just each one separately. This research shows that companies often forget this, and it's important to have a plan for user experience that works for the whole product family.

How to use in your project

1.Reference this study when discussing the importance of a consistent user experience across multiple product iterations or variations in your design project.
