Too many system integration providers promise a simple journey to success, but in reality, this is far from what ends up happening.
At ONEiO we've seen through countless successful system integrations, and we have observed some clear mistakes. A common pitfall is saying... "I just need to integrate these systems with each other – what does it cost?"
Here are 9 important questions to ask when starting a system integration project:
1. Why are you integrating?
2. Do you have a Project Manager?
3. What other resources do you need?
4. What systems are you looking to integrate?
5. Are your systems running in the cloud, on-premise or hybrid?
6. Do you have enough knowledge of the systems you are integrating with?
7. Have you defined the use case you are looking to integrate?
8. Have you defined the field and value mappings?
9. Have you defined a test scenario that you are looking to run?
So how do we stop this from happening?
There are many things to take into consideration when thinking about the whole integration project and we want to help you identify and address these.
The real question is: "How do we do it and how much does it cost?".
To answer that, there are 9 vital questions to be answered first.
1: What are you integrating?
This is a multiple-choice question, and here are your options:
- Customers
- Service Providers
- Internal systems
Why are we asking this?
Integrations always have (at least) two ends. It's important for you to understand that the complexity of the project might vary between these parties. Are you able to control both ends, does the customer or service provider have somebody from their end to work with you?
2: Do you have a Project Manager?
- We have someone in-house who runs the show
- The service provider or customer is providing the Project Management
- We are using an external provider / consultant on the project management
Why are we asking this?
Like in any project the manager plays a crucial role in the success of the end result and keeping the elements together.
3. What other integration resources will you need?
- Tool admin?
- Integration architect?
- Process owner?
After you have sorted out questions 1-3, we can move forward. And now the project will be divided into two tracks. Technical and process tracks.
Let's start with the technical track.
4: What systems are you looking to integrate?
- Application 1: __________________
- Application 2: __________________
- Application 3:___________________
- Application n:___________________
Why are we asking this?
The complexity of the system and depending on how sophisticated it is might have an effect on the total time and effort needed to execute the project. We have seen all kinds of interesting systems and API's in our life.
5: Are your systems running in the cloud, on-premise or hybrid?
- Cloud
- On-premise
- Both
Why are we asking this?
This might not have a direct cost related to the project, but it might slow things down. When opening firewalls and allowing IP addresses there are usually certain policies in place and those might take some time. So take this into consideration when planning the system integration project and thinking of the timeline.
6: Do you have enough knowledge of the systems you are integrating with?
- I know my own tool
- I know both tools
- I have no knowledge over these
Why are we asking this?
It's more of a fact than a myth that all tools and their characteristics are individual and designed in a unique way. Even if we avoid having to make changes in the corresponding systems. Sometimes you need to be able to create some triggers or web-hooks from your own system. Especially if you have something custom build.
7. Have you defined the use case you are looking to integrate?
- Yes
- No
- Sort of... (maybe you get the process, but it hasn't translated into a genuine use case yet)
Why are we asking this?
First of all, let's address the question: "What is a use case, really?"
Our experience shows us that the most important thing to understand is what are you looking to achieve. Meaning what is it that you are looking to do on a process and logical level? This is the most important part of a successful integration project and will define a lot on the length and success of the project.
8: Have you defined the field and value mappings?
- Yes, the fields and values to be mapped are clear
- Our side is done, waiting for the other side
- Nope..
Why are we asking this?
Mapping the fields and values that will be exchanged in the integration and the use case will ease the actual configuration work when setting up the integration.
9: Have you defined a test scenario that you are looking to run?
- Yes
- No
Why are we asking this?
When the configurations have been made to accommodate the use case, there should be testing involved. The test scenario and acceptance criteria's should be agreed with the parties prior to know if the project was successful!
Now, what is the expected cost of system integration?
Unfortunately, we can't answer without seeing your systems up close (boo!).
But it is very quick and easy to do, and 'just looking' won't cost you a dime. However, we are 100% certain that we can help you reduce the total cost of delivery with your next integration project.
This is great news for you because it means more profit, better value for your customer and a faster time to value.
At ONEiO, we have over 20 years experience in integrations. We've been there, and done that. We've seen all the pitfalls and successful projects.
Based on our vast experience we've created a tool to assess your integration needs and help with Request For Proposals for integrations and integration platforms. We call it Integration Landscape Assessment.

Questions and Answers
What does a system integrator do?
A system integrator is person or company that brings together different computing systems into a cohesive IT solution for an organization. A system integrator either specialize in integrating software, hardware or data storage solutions - or have a broad responsibility over different kinds of systems based on business needs.
How can you prepare for a system integration project effectively?
You can follow our system integration checklist which identifies nine key questions you should answer when preparing for your integration project.
What are the common challenges of system integration?
The primary challenges of system integration include the complexity of integrating disparate systems with different interfaces and technologies, ensuring data consistency and integrity across the ecosystem, managing the costs and resources required for integration projects, and maintaining the security and compliance of integrated systems. These challenges require careful planning, expertise, and often, the use of specialized integration tools or platforms to address effectively.
How does service integration differ from system integration?
Service integration focuses on managing and harmonizing multiple service providers' efforts to ensure cohesive service delivery that aligns with business objectives. It encompasses processes, people, and technology across various service domains. In contrast, system integration primarily deals with linking together different computing systems and software applications physically or functionally, to act as a coordinated whole within the IT infrastructure.
How do we ensure system integrations support business agility rather than slow us down?
System integrations often become the bottleneck that prevents business agility—changes to systems require integration updates, new capabilities are delayed waiting for integration work, and the fear of "breaking integrations" causes organizations to avoid beneficial system upgrades. Ensuring integrations enable rather than constrain agility requires fundamentally rethinking how integrations are managed.
The traditional project-based integration model inherently limits agility. Each change requires scoping a project, allocating resources, developing custom code, testing, and deploying—a cycle that takes weeks or months. Even worse, integrations become brittle over time, requiring careful coordination whenever any connected system needs to evolve. This creates organizational friction where business leaders avoid changes because "it will break the integrations."
ONEiO's Integration Ops approach directly addresses agility constraints through its Adaptation Without Limitations philosophy. Your ITSM platforms can evolve independently—ServiceNow can upgrade, Jira can enable new features, vendors can implement best practices—without breaking integrations. ONEiO automatically adapts to changes, eliminating the coordination overhead and integration rework that traditionally slows business evolution.
How can you reduce system integration costs without compromising service quality?
The most effective way to reduce integration costs while maintaining or improving service quality is shifting from project-based integration investments to Integration Ops as a Service—treating integration as a managed operational function rather than repeated capital expenditures.
ONEiO's Integration Ops model transforms the cost structure of integrations for enterprise leaders. Instead of funding separate integration projects with unpredictable budgets, variable timelines, and ongoing maintenance costs, you move to a predictable OpEx subscription that includes not just technology but complete operational management by integration experts.
The cost reduction comes from multiple sources. You eliminate the need for dedicated integration specialists on staff—ONEiO's experts become an extension of your team. You avoid the hidden costs of integration failures, downtime, and constant troubleshooting that plague traditional approaches. The standardized, repeatable delivery model means you're not paying to rebuild similar integrations from scratch each time. Most importantly, ONEiO's Adaptation Without Limitations approach means your systems can evolve and upgrade without expensive integration rework projects.
ONEiO offers three service tiers—Self-Managed, Co-Managed, and Fully-Managed—allowing you to optimize the balance between cost and control based on your organization's needs. The Fully-Managed tier delivers maximum cost efficiency by completely eliminating internal integration operational overhead.
Enterprise leaders implementing Integration Ops report significantly lower total cost of ownership compared to traditional integration approaches, while simultaneously improving integration reliability and enabling faster business agility. The predictable subscription model also simplifies financial planning and shifts costs from capital-intensive projects to operational budgets that scale with business value.
