What is a System Development Company?

A system development company is a company that specializes in planning, designing, developing, implementing, and maintaining systems and software.

System development generally refers to building various mechanisms to improve business efficiency using IT technology.

The tasks involved in system development are vast and varied. The technologies required for each project differ, and it is not uncommon to need high-level expertise or the latest knowledge.

To move forward with system development, it is essential to have engineers, programmers, and project managers with the necessary expertise.

However, some companies may not have the required personnel or know-how for development, making it difficult to handle system development in-house. In such cases, an external system development company is selected.

By selecting the right system development company for your business, you can secure talented engineers and leverage their high technical skills for development.

Below, we will introduce recommended system development companies.

Assignable resources

During business meetings and discussions, ask questions about any concerns you may have or have an in-house employee knowledgeable in system development accompany you to obtain accurate information.

Selecting by Specialty

Even among system development companies, each has its own area of expertise. Assess compatibility with your company based on your requirements.

System development requests can range from website, app, and web service creation to AI and IoT-based system development.

Some companies specialize in UI/UX design, IT consulting, or strategic planning.

Researching the strengths of different companies can help you determine compatibility. Checking the programming languages and frameworks they use is also recommended.

Selecting by Proposal Capability

After researching potential companies online, schedule a meeting. It is recommended to select based on their proposal capabilities.

Proposal capability refers to the ability to listen to what you want to achieve, understand your business, and make optimal suggestions.

Evaluate whether they can provide solutions to IT and DX-related challenges. Delivering what is requested is essential, but the ability to proactively propose improvements is also crucial for a better product.

Choose a company that listens carefully to your system development goals and IT/DX challenges while also considering future business expansion.

Additionally, evaluating whether you get along with the representative during meetings is important. The representative will lead the project and be a long-term collaborator.

Therefore, check for compatibility. Assess their attentiveness, response speed, personality, and communication skills to determine if they are trustworthy.

Ways to Reduce System Development Costs

Let's take a look at how to reduce system development costs.

Start small with only the necessary minimum functions
Clearly define specifications and scope of work

Let's break these down.

Start Small with Only the Necessary Minimum Functions

If your budget is limited, instead of developing a large-scale system all at once, it is better to start small with only the necessary functions. By limiting development to only the essential functions, you can reduce labor costs.

However, be careful not to cut down on essential functions. If you have features you would like to add in the future, sharing them with the development company in advance can help ensure efficient development.

By narrowing down to the minimum core functions and designing a flexible system that allows easy addition of new features later, you can maximize cost performance.

Clearly Define Specifications and Scope of Work

Clearly defining the specifications and scope of work will help reduce the overall cost by cutting down on unnecessary work.

If specifications are not clearly defined at the initial stage, the risk of troubles and rework during development increases.

Additionally, if the scope of work is ambiguous from the start, communication gaps may arise, or irregularities may cause delays in the development timeline.

By clearly defining specifications and scope beforehand, development can proceed smoothly, ultimately leading to cost savings.

If You Are Unsure About Choosing a System Development Company, Consult with "Solashi"

We have introduced recommended system development companies and how to choose one.

Since each system development company has different characteristics and strengths, it is important to choose one that matches your development needs.

If you are unsure about choosing a system development company, please consider Solashi Co., Ltd. We offer high-quality system development at a reasonable cost.
