Change management in hardware and software projects is an essential area that determines the pace of innovation, costs, and the risk of implementing new solutions. As Mary Poppendieck, author of Lean Software Development, aptly puts it: “In hardware, change is painful. In software, change is the only constant”.

In hardware projects, change often means the need for design modifications at the physical level. This can include:

• updating integrated circuits,
• adjustments in the manufacturing process,
• a complete reconfiguration of components.

This implies not only extensive validation testing but also impacts the supply chain and compliance with regulatory standards. The time required to implement a change is therefore incomparably longer than in the case of software, and the costs can grow exponentially the later the change is introduced in the product development cycle. That’s why strategies like modular component design or interface standardization are popular in the hardware industry — they help minimize the negative impact of later modifications.

In software, change management is based on a completely different philosophy — here, iteration and adaptability are the foundation of effective product development. Implementing modifications is relatively cheap and fast, and modern approaches such as CI/CD (Continuous Integration/Continuous Deployment) allow for immediate delivery of changes without system downtime. According to State of DevOps Report from 2023, thanks to continuous testing and feedback loops, software teams using the CI/CD approach report a 50% faster time-to-market and 30% fewer post-deployment defects. The ability to dynamically introduce fixes and new features is a major competitive advantage for many tech companies. Automated testing, performance monitoring, and real-time user feedback enable continuous product improvement — something that is virtually impossible in the hardware world.

The biggest difference between change management in hardware and software lies in the timing of decision-making. In hardware projects, it is crucial to anticipate and minimize the need for future changes already at the design stage. That’s why such importance is placed on:

• simulations,
• laboratory testing,
• thorough risk analysis.

In software, on the other hand, changes are a natural part of the product lifecycle and often constitute its market advantage. Well-managed DevOps processes allow for continuous product evolution, whereas in hardware, every change requires a new production iteration.

Methodologies based on rigorous planning, requirements engineering, and risk management play a major role in hardware projects. Common approaches also include Design for Manufacturability (DFM) and Design for Testability (DFT) — these practices assume that production and testing constraints are taken into account already at the design stage, which helps avoid costly modifications in the later phases of a project.

In contrast, in the software environment, the dynamic nature of change, the complexity of business logic, and the need to respond quickly to user needs make agile methodologies fundamental, such as:

• Agile,
• Scrum,
• Kanban.

These are designed for iterative value delivery, rapid validation of product hypotheses, and flexible scope management. Software — being intangible — allows for easily reverting to earlier stages, applying fixes, or experimenting with different solutions without needing to halt the entire process.

Moreover, in recent years, practices like Site Reliability Engineering (SRE) have become increasingly significant. These approaches shift the responsibility for quality and reliability from infrastructure teams to development teams, integrating development and operations. They’ve transformed the way we think about processes — focusing not only on efficiency but primarily on resilience, meaning the ability of systems to adapt and recover from failures.

From the perspective of IT professionals, the most inspiring aspect of these differences is the potential to transfer selected practices between domains. Hardware teams are increasingly experimenting with iterative approaches (e.g., rapid prototyping or hardware-in-the-loop testing), while software teams are adopting more rigorous methods to requirements engineering and validation, especially in safety-critical or embedded systems projects.

In hardware projects, costs are largely upfront, capital-intensive, and closely tied to physical infrastructure. They include:

• the purchase of materials and components,
• prototyping costs (e.g., 3D printing, milling, PCB fabrication),
• access to laboratories, measurement tools, and certifications,
• mass production and logistics.

What’s more, the procurement cycle in hardware requires close collaboration with suppliers, planning for component availability, and often reserving manufacturing capacity well in advance. Any design error may result in the need to order new batches of materials or conduct costly redesigns. As a result, hardware engineers learn to treat cost as a function of design risk — even a small change in requirements can have a cascading effect on total costs.

In the software world, the situation is entirely different. Costs are more operational, primarily related to team labor time, IT infrastructure (servers, cloud), and development support tools. The most important asset is the competence of the team, not physical material. It’s the availability of the right talent — backend, frontend, DevOps, QA — that determines the success of the project. Importantly, most software costs can be scaled and distributed over time, thanks to subscription models, outsourcing, or serverless solutions.

For technical leaders in IT, a fascinating difference is that in software projects, resources are almost entirely intangible, yet their performance and quality depend on factors such as:

• the maturity of team processes,
• the quality of communication,
• the level of pipeline automation,
• and an organizational culture that supports experimentation.

In software, you don’t pay for “material” — you pay for people’s ability to create value and respond quickly to change. With well-designed architecture and a healthy work culture, it becomes possible to minimize the cost of rework and deliver business value faster. In practice, this means that software can be just as “expensive” as hardware — but that investment translates directly into agility and adaptability, something hardware inherently lacks.

For IT professionals, especially inspiring is the strategic approach to costs in hybrid projects — such as IoT, embedded systems, or edge computing — where hardware and software must work in harmony. In these projects, the true advantage lies in the ability to:

• maximize the value of software while minimizing hardware iteration costs,
• predict costs at the system level (not just at the component level),
• integrate financial planning with the technology roadmap.

Choosing InTechHouse for your next hardware and software project management challenge

A modern project manager must not only understand the specific nature of the product type but also be able to combine the best practices from both worlds—agility and flexibility typical of software with the precision and discipline inherent in hardware projects. Only then is it possible to create modern, scalable, and durable technological solutions that truly meet the real needs of the market.
