Your product already exists. It may be in customers’ hands, moving towards production, or sitting on a workbench as a promising prototype. But the next development step has become difficult.
Perhaps the original developer is no longer available. Your internal team may lack the capacity for a major upgrade. Or reliability issues, unavailable components, and manufacturing costs may be holding the business back.
A new development partner can take over an existing electronic product. The first step is to establish what works, what needs attention, and whether the proposed investment makes business sense.
A takeover does not automatically require a complete redesign. Depending on the product and the available information, the right approach may be a focused repair, a subsystem upgrade, or a more substantial redevelopment.
1. Start with the business outcome
Before deciding what to change, define the problem the investment should solve. For example:
- Product failures are increasing warranty costs.
- Assembly takes too long to support higher production volumes.
- Customers need functionality the current hardware cannot support.
- Critical components are becoming difficult to source.
- Development depends on a supplier or individual who can no longer provide support.
Then define the intended outcome. That might be fewer service visits, simpler assembly, longer battery life, or the ability to maintain the firmware independently. Separate essential requirements from desirable improvements. Identify constraints too: the enclosure may need to remain unchanged, existing accessories may need to stay compatible, or production may need to continue throughout development.
You do not need to have every technical answer before approaching Krakul. Our development process begins with understanding the problem and its constraints before defining the technical solution.
2. Establish what you can hand over
A takeover becomes easier to assess when our team can inspect both the product and the information behind it.
Gather what you have:
| Useful handover material | |
|---|---|
| Electronics | Schematics, editable PCB design files, component lists, and manufacturing files |
| Firmware or software | Source code, version history, build instructions, and details of required tools |
| Mechanical design | Enclosure drawings, editable design files, and assembly instructions |
| Testing and compliance | Test procedures, results, relevant reports, and technical documentation |
| Production and operation | Supplier details, programming procedures, known faults, and service records |
| Product samples | Working devices and, where available, examples showing reported failures |
Check whether the files correspond to the version currently being manufactured or used by customers. An archive can look complete while describing an older revision.
Also establish your rights to use and modify the materials and your access to the systems needed to support the product. Possessing finished devices does not necessarily mean having the source files, permissions, or account access needed for further development.
What if documentation or source code is missing?
Incomplete documentation does not automatically prevent a takeover, but it changes the work required.
For example, firmware source code without build instructions may require the new team to reconstruct the development environment. Having only a programmed device, with no source code, may mean that replacement firmware or more extensive changes must be considered.
The important question is whether another team can reproduce, test, and safely modify the product using the available information. Where it cannot, the assessment should identify the gap and investigate its implications before a full development commitment.
You can start the conversation with incomplete materials. Explain what you have and what you know is missing.
3. Compare improvement and redesign options
An existing product represents valuable engineering work and knowledge gained from customers. An assessment should identify which parts remain suitable for the next stage.
There are usually three options to compare:
| When it may make sense | |
|---|---|
| Targeted improvement | The architecture remains suitable and the problem is isolated |
| Subsystem redesign | One board, module, or software component limits progress |
| Broader redesign | Several limitations prevent the product meeting its next requirements |
The smallest design change is not always the lowest-cost route overall. Repeated fixes to a constrained design may consume more effort than replacing the limiting subsystem. Equally, a broader redesign may introduce costs and risks that a focused improvement avoids.
Compare the options against your expected production volumes, remaining product lifetime, support needs, and business priorities.
Krakul’s MedTech device upgrade illustrates work on a product originally developed by another company. Reviewing the existing hardware and firmware led to a more thorough reengineering approach, including changes to the PCB and microcontroller while preserving the mechanical dimensions.
The Bikeep project shows another situation: evolving an existing product to simplify assembly, improve power efficiency, and support additional functionality.
These projects address different starting points. For your product, the scope should follow the findings of the assessment.
4. Protect production and existing customers during the transition
Developing an improved version is only part of the task. You also need a plan for the products already in use and those still being manufactured.
You may be able to stop producing the old version once the new one is launched. Alternatively, both versions may need to coexist because customers replace equipment gradually, existing installations need support, or different markets have different requirements.
Our team can help you assess these options and plan the transition around your business. Our consultancy and engineering services help connect those business decisions with their technical consequences. The aim is to establish a manageable route from the current product to its next version, with clear responsibilities and release criteria.
5. Use an initial assessment to make the development decision
Before committing to further development, you need a clear understanding of your existing product and a credible plan for improving it.
Our initial assessment package gives you a structured engineering review to support that decision. We agree on the assessment scope together, based on your product, available materials, and the questions that matter most to your business.
Our engineers work with the current product and its documentation to understand its design, investigate constraints, and assess the proposed direction. This work requires dedicated engineering time. That time allows us to investigate the product properly and produce recommendations grounded in technical evidence.
The assessment does not commit you to the full development project. It gives you a basis for deciding, together with us, which work to undertake, in what order, and within what budget and timeframe.
Some findings may support moving directly into development. Others may show that a focused test or further investigation should come first. Either way, you gain a clearer understanding of the product you have and a practical route towards the product your business needs.
Contact us to discuss your product and its next stage. Together, we’ll identify the right improvements and a practical way forward.
