COMPANY OVERVIEW
A systems company of the Nippon Gas (Nichigas) Group
Kumo no Uchusen Inc. is a systems company of the Nippon Gas (Nichigas) Group. Its business centers on the development and operation of systems, including "Kumo no Uchusen," a business-support cloud platform for the energy industry. It centrally manages meter reading, delivery, and safety operations on smartphones, supporting greater operational efficiency and safety. Headcount of 40.
CHALLENGES & BACKGROUND
Switching from the incumbent vendor. Revamping the app for external sales
01
Issues with pricing and contract type
They had issues with the incumbent vendor: "the pricing felt high" and "only quasi-mandate contracts were possible, with no contract-for-work option." They considered switching at the timing of additional development.
02
Concerns about vendor lock-in
To avoid the system becoming dependent on individuals through continued reliance on a single vendor, they wanted to build a development structure that used multiple vendors.
03
Improving the field app and preparing for external sales
They needed to improve the usability of the digital safety app for field workers and change the specifications to allow external sales beyond Nichigas.
SYSTEMI'S APPROACH
Acquiring domain knowledge from a three-month handover and carrying out more than 10 feature improvements
1
Handling the handover from the previous vendor
Within a short three-month handover period, grasped the complex design and module structure of the existing system. Where information was missing, they investigated and filled the gaps themselves.
2
Acquiring domain knowledge of the gas business
Actively attended training sessions held by the client. They approached the improvements only after understanding the details of field operations and the characteristics of the gas business.
3
Carrying out more than 10 UI/UX improvements
Made numerous UI/UX improvements aligned with field workers' workflows. Significantly improved on-site usability, such as the absence-slip entry screen.
4
Ongoing technical improvement proposals
Going a step beyond the "if it works, there's no problem" mindset, they continued to make proactive improvement proposals from the perspectives of cost, maintainability, and UX.
RESULTS
Evolving into an app that gets used in the field
10+
UI/UX improvements completed in 3 months
Fast turnaround
3 months from estimate to kickoff
External sales ready
Spec changes for sales beyond Nichigas
"At SYSTEMI there are many people who 'hear one thing and understand ten.' They pick up on unspoken needs and proactively propose and act ahead of us, and I feel this quickness on the uptake and smooth communication is what drives their improved responsiveness."

INTERVIEW
Diverse expertise and an "attitude of standing alongside the client" are their strengths. SYSTEMI's proposal and execution power that turns customer requests into reality
Kumo no Uchusen Inc. develops and sells cloud systems for the energy industry. We spoke with Section Manager Mr. Kikukawa and Senior Associate Mr. Mizumura about how they switched to SYSTEMI at the timing of feature improvements to their digital safety app, and their impressions.

Q
Could you tell us why you switched vendors from the previous development engagement, and why you chose SYSTEMI?
Mr. Mizumura

Of course the vendor we'd worked with before was excellent too, but we had issues with "(1) the pricing felt high" and "(2) only quasi-mandate contracts were possible, with no contract-for-work option," so at the timing of additional development we considered switching to another company.

Mr. Kikukawa

We also had a concern that continuing to place orders with the same vendor might lead to vendor lock-in. To avoid a future where the system became dependent on individuals through reliance on one specific vendor, we thought it would be better to place orders with a different vendor.

I'd known of SYSTEMI since my previous job, and I had the impression that Mr. Ogushi, the sales lead, was someone worthy of trust. He'd given us proposals several times on other projects, and he never said "no" to our requests — he always stood alongside us as much as he possibly could. In the end, there was a reassuring sense that "this person can keep the field under control." The fit and validity of the proposals mattered, of course, but ultimately the deciding factor was the trustworthiness of the person in charge.

Q
Specifically, what kind of development did SYSTEMI take on?
Hiramatsu, SYSTEMI

To make the system easier for field workers to use, we carried out a wide range of improvements. We standardized various data imported from external sources into a single format, and we made UI/UX improvements to the system. UI/UX improvements directly affect how easily field workers can do their jobs, so we carried out more than 10 of them.

Mr. Mizumura

To give one example: when filling out an absence slip during meter reading, workers enter it while looking at the "absence registration screen," but the codes and addresses they needed weren't displayed, so they had to go back to a different screen to check — and we'd heard complaints that this was inconvenient. For a single case it might not be much trouble, but when the same effort occurs across multiple cases it's inefficient, and it's stressful for the field workers too.

Mr. Kikukawa

So that they could revamp the system to better fit our operations, we held a training session for them during the handover period and walked them through the details of field operations and the gas business. Because they took such a positive attitude toward acquiring domain knowledge, the engineers had a high level of understanding of the work, and we could entrust the improvements to them with peace of mind.

Q
If there's anything you found particularly good about working with SYSTEMI, could you share it?
Mr. Mizumura

This time, the period from when we requested the estimate to when they began development was short — just three months — yet within that window they handled the handover from the previous vendor and absorbed the domain knowledge, which was a tremendous help. It was also reassuring that they'd offer suggestions like "it'll be even easier to use if you revamp it this way" or "there's this kind of cost advantage to doing it like this."

Mr. Kikukawa

A really good point about SYSTEMI is how nimble they are. They're light on their feet, and when there was trouble in the past, they immediately gathered people and responded. They're also often flexible when there are changes to the development process, which I feel is a sense of speed unique to a mid-sized company. There are many people who "hear one thing and understand ten" — they pick up on unspoken needs and proactively propose and act ahead of us, and I feel this quickness on the uptake and smooth communication is what drives their improved responsiveness.
