Strategic Value of Reverse Engineering

What is the business case for dissecting an existing product?

In my earlier article, I discussed the misconceptions surrounding reverse engineering. The point was examination of a product should be considered evidence and not a blueprint.

Typically, when you mention reverse engineering, you think about taking a competing product apart, measuring things, studying how its put together and functions, Then, you take that information and engineer your own product using the research as a blueprint. But that’s only part of the strategic reasoning why a business might actively engage in reverse engineering.

The above approach can make perfect business sense in that it can flatten the development curve as opposed to creating something from scratch. However, reverse engineering is not merely a technical activity. It can be a deliberate business strategy for reducing uncertainty, accelerating development, protecting margins, or changing a company’s competitive position. For a physical-product OEM or industrial business, these can be grouped into seven categories.

Strategic Reasons to Reverse Engineer

A business might incorporate reverse engineering for several reasons and not just technical. When I worked with a start-up early in my career, I reverse engineered a competing heat shield with the intent of solving the durability issues reported in the field. I was also faced with a challenge of having to make the assembly within the available manufacturing capability of the company. It was necessary to not only take the old assembly part but also diagnose why its life was limited. In the end, resulting product remained nearly the same, but delivered nearly twice the service life. In this case the reasons were clear with defined objectives.

For a physical-product OEM or industrial business, these reasons can be grouped into seven categories.

1. Reduce product development cost and time – This is probably the most common and straight forward reasons for implementing reverse engineering. The existing product can serve as a starting point. The company can examine the details and structure, its interfaces, materials and make logical estimates of the manufacturing methods involved in producing the product. This saves a considerable amount of time in that its not necessary to recreate all the engineering decisions. The business value then becomes lower development costs, shorter times to market, with fewer design iterations.
2. Understand a competitor’s product – When a competitor’s product is examined in detail, certain information can be revealed on how the product achieves its performance and its limitations. Once those are understood, it’s possible to make more informed business decisions regarding where to focus research and development activities and costs. By examining the product, a business can obtain informed product positioning and develop their product to outperform thus differentiating itself in the market.
3. Replace obsolete or unavailable components – Sometimes, an original equipment manufacturer or supplier is unable to continue supplying parts. This can be in the form of discontinuing operations or manufacturing that item, regardless the reason, the part will no longer be available for a product. Reverse engineering can redesign the part to preserve the functionality of an existing machine or system. After all, why should a production operation cease functioning because they can no longer get parts to maintain their machinery. The business value then becomes reduced downtime, extending asset life, and increased in supply-chain resilience by reduced dependency on a single supplier.
4. Diagnose failures and performance problems – Examining a failed or underperforming product can uncover design weaknesses. Using a forensic approach, its possible to identify the deficiencies and work through ways to correct or improve in future iterations or identify a root cause of the problems. This can lead to fewer warranty claims, more effective correction actions and reduce the likelihood of reoccurrence.
5. Recover missing engineering knowledge – Older products may have engineering drawings and models lost to time. Modification history may be lost, and tribal knowledge may have retired means the reasons things were done a certain way are gone for good. When a business implements reverse engineering, they can reconstruct some of that lost reasoning and establish a usable technical baseline going forward. It restores engineering capability under more current configurations controls and reduces the reliance on institutional knowledge.
6. Identify opportunities for redesign and improvement – A company can use a existing design as evidence of what works. They then investigate weight reduction, part consolidation, manufacturability, reliability, serviceability, or cost reduction. The goal is to improve margins, produce a better product and lower lifecycle costs.
7. Validate a strategic acquisition or investment – A prospective buyer, investor or business owner may need to understand the actual engineering, quality, manufacturability, reliability, or technical maturity of a product before committing capital. Reverse engineering can help establish what the product is, how it works, and what engineering work remains. It can also identify potential issues which could turn into a liability later. Thus, a business can make better informed capital allocation decisions, more realistic integration plans, and understand the technical risks.

The Deeper Business Rationale

These seven categories above have a common thread: reverse engineering converts existing physical artifacts into actionable knowledge.

That knowledge can reduce uncertainty in decisions about product development, sourcing, manufacturing, investment and risk. For the thermal panel I mentioned above, the key issues were making it within the capabilities of the start-ups manufacturing operations, and how to reduce the customer headaches of dealing with an existing design which had a less than desirable service life.

Now consider an original equipment manufacturer which buys and incorporates a proprietary assembly within their own market facing product.  That supplier experiences a shutdown such as a natural disaster, financial insolvency or their own supply chain issues, the OEM is now directly downstream of the issue and experiences the impact. Management is then faced with several options:

• Redesign the entire product around new assemblies.
• Find another supplier with a compatible assembly.
• Purchase whatever remaining inventory exists to delay the impact.
• Reverse engineer the assembly and develop a qualified replacement.

Now in certain conditions, the OEM could offer to buy the existing engineering from the supplier depending on the circumstances. Otherwise, reverse engineering becomes strategically attractive in so long as it offers a favorable balance of cost, time, technical risk, and long-term control compared to the other alternatives.

Obviously, the best alternative is to never get into a situation where a company is so dependent on a supplier that a disruption is catastrophic. Unfortunately, that’s not always possible.

When Does it Make Economic Sense?

A simple decision model is:

The relevant cost and benefits should be measured against the next-best alternative and not against doing nothing.

For example, an OEM might spend $150,000 to reverse engineer, redesign, test, and qualify a discontinued component. If the alternative involves $400,000 in redesign and integration costs, the reverse engineering may be the more attractive option. However, if the replacement introduces substantial reliability or certification risks, the apparent savings may disappear.

Reverse Engineering a Strategy Instead of a Project

The heat shield issue was clearly a reverse engineering project. It was a business response to a specific problem involving a specific component. The supply chain disruption scenario presents a similar decision on whether to reverse engineering an existing assembly or reengineer the larger system around an alternative. Both are examples of reverse engineering undertaken in response to an immediate need, rather than as part of a formal corporate capability.

A company taking a strategic approach might establish standard procedures for acquiring competitor products, documenting designs, characterizing materials, testing performance, assessing intellectual property constraints, and deciding when to reuse, redesign, or replace a design. Over time, this approach can develop into a competitive capability rather than a series of isolated engineering assignments.

Boundaries of Reverse Engineering

Reverse engineering is not a universal shortcut as several constraints can undermine the strategy:

• Intellectual property – Patents, trade secrets, copyrights, contracts, and applicable laws can limit what can be examined, copied, or commercialized. While lawful access to a product grants access to its information, it does not automatically authorize every use of that information.
• Technical uncertainty – External geometry alone rarely determines material properties, fatigue life, internal stresses, process controls, or full operating capability.
• Qualification requirements – Aerospace, defense, medical, and other safety-critical applications often necessitate extensive verification, validation, traceability, and formal approval.
• Economics – A replacement that costs less to manufacture may cost considerably more to develop, validate, and support.
• Strategic dependence – Copying an existing product without understanding its weaknesses can reproduce the original limitations rather than create an advantage.

These constraints reinforce the need to evaluate reverse engineering as a business decision, not simply an engineering exercise.

In Closing

For the OEM manufacturing a physical product, the strongest justification for reverse engineering is often the ability to make better-informed business decisions by understanding something the company previously did not. That knowledge might inform whether to develop a product, discontinue one replace a supplier, enter a market, invest in an acquisition, or accept a technical risk.

Why then, should a business invest resources in reverse engineering?

Because examining an existing product can help a business:

• Reduce development cost and time
• Improve competitive positioning
• Mitigate supply-chain risks
• Diagnose problems
• Recover lost knowledge
• Improve economics
• Make better-informed investment decisions

Ultimately, the business case rests on whether the knowledge gained enables better decisions or creates economic value the exceeds the costs of the efforts. When a business looks beyond simply creating a clone, reverse engineering becomes a tool for informing product development, operations, sourcing, investment and competitive strategy.
