FEATURES

Successful system development requires more than just technical expertise; it demands a partner who can deeply understand the core of the problem and respond with flexibility. Sola completes every project entirely with in-house engineers, achieving both speed and quality. We deliver optimal solutions tailored to your business and guide your projects toward reliable, measurable success.

Challenges We SolveWhy do projects fail to move forward?
We address the root cause
with technology.

The challenges many companies face in system development are not simply caused by a lack of technical capability. Structural factors such as insufficient alignment on objectives and requirements, dysfunctional project management, and communication loss caused by outsourcing are deeply intertwined. In Japan’s IT industry in particular, multilayer subcontracting structures have become chronic, and projects often proceed without frontline engineers understanding the background behind why a given specification is needed. In this structure, accountability tends to become ambiguous, rework and specification drift occur frequently, and projects ultimately stagnate.

Examples of Specific Challenges

Projects never seem to reach completion

The project moves forward with vague requirements, while misalignment with external vendors and delayed coordination continue to accumulate until the delivery timeline becomes unclear.

Objectives, requirements, and designs are not accurately communicated to engineers

When intermediary vendors are involved, background information is often insufficiently shared, creating a constant risk that the final deliverable will deviate from the original intent.

There are no in-house engineers who can handle PoCs or niche technologies

It is difficult to secure specialized talent, causing teams to stumble during fast-moving validation phases. As a result, technical verification itself can become the goal.

Operations cannot be handled by ERP or SaaS products

Generic packages do not fit the details of actual business operations, forcing the operational side to adapt unnaturally. Dissatisfaction from the field only continues to grow.

And many other industry-specific challenges...

Sola’s StrengthsQuality, speed, and flexibility
made possible because
we do not subcontract.

At Sola, every phase of a project is completed entirely by our in-house engineers. Through a consistent team structure, we ensure strong understanding, speed, and continuity. From requirements definition to maintenance and operations, we can respond flexibly with the right scope and structure for each need. As a reliable partner without outsourcing risk, we help lead your development project to success.

01Quality

Because we never subcontract and complete projects only with our in-house engineers, responsibilities are clear. Members who are involved from requirements definition can continue contributing through operation, maintenance, and expansion after development, allowing the project to grow with the intent and background of the specifications fully understood. Taking ownership of the entire project context is Sola’s approach to quality.

02Speed

The speed of project launch and the ability to respond quickly to unexpected team changes are directly tied to development success. At Sola, we can immediately assign the most suitable talent from our in-house engineers, enabling fast startup and flexible recovery during the project. Our major strength is balancing speed and flexibility, including scaling the team up or down according to each phase and workload.

03Flexibility

Sola is a system development company centered on contract development. We can support a wide range of cases, from handling an entire project end to end to taking responsibility for only a specific area. We also respond flexibly to phase-specific support, including applications, infrastructure, requirements definition, and maintenance operations. We are accustomed to working alongside clients as part of their own teams, enabling optimized roles and structures.

Common Consultation Cases

Past development or operations projects did not go well

Most issues in system development and operations stem from: (1) insufficient understanding by engineers of objectives, requirements, and design; (2) dysfunctional project management; and (3) a lack of viable options for project recovery.

At Sola, we do not outsource projects. Instead, we form teams exclusively with in-house engineers and handle all phases of development independently, including technical domains. Our dedicated engineering team, fully understanding your business context, system requirements, and design background, works alongside you through to project completion while flexibly scaling the team as needed.

There are technologies that cannot be handled internally or by existing vendors

In developing new IT-driven products and services, Proof of Concept (PoC)—validating feasibility from a technical perspective—is often required. The most critical factor in PoC is speed. It is difficult to secure engineers skilled in advanced or niche technologies in-house, and even if possible, long lead times can undermine the objective.

Sola has a broad range of technical capabilities across the organization. In addition to our contract development business, we maintain an in-house R&D team, enabling us to support a wide variety of PoC needs with agility and technical depth.

There are requirements that cannot be fulfilled by ERP or SaaS

While ERP and SaaS solutions are convenient, they are designed to address the broadest common market needs. As a result, they may not fully accommodate companies with highly unique business models or operational characteristics. Additionally, depending on workforce size and structure, significant changes to existing workflows may lead to decreased performance.

Sola provides fully customized system development starting from the requirements definition phase. We deliver solutions tailored to each client's needs, ensuring essential functionalities are met while also creating systems that are intuitive and easy to use for on-site users.

An internal engineering team alone cannot ensure a stable structure

Demand and mobility for IT engineers are high in the labor market, making hiring difficult and sudden turnover a real risk. Particularly for early-stage companies, a mismatch between the speed of business growth and the pace of building an engineering team can hinder overall progress. Additionally, teams are often lean due to cost considerations, so the departure of even one engineer can have a significant impact.

Because Sola does not rely on subcontracting, we can respond quickly and flexibly to diverse client needs—including technology stacks, expected roles, and project durations—allowing us to integrate into projects rapidly.
