MedicalCare Net Co., Ltd. — Build Story

From paper surveys and individual know-how,
74 items Assess in 5 minutes。

CareLogic is a long-term care insurance primary-assessment simulator for care providers. Enter the 74-item certification survey form through an 8-step wizard, and an assessment engine compliant with MHLW logic instantly computes from Support Level 1 to Care Level 5.

A new-platform launch story: three field challenges — "the training speed of new care managers," "veteran-dependent judgment know-how," and "the offline environment during training" — built in-house from scratch with Amela in 6 months.

CHALLENGE

Design challenges to solve

Care-staff development and assessment quality: four design challenges.

Not mere tool development, butTalent-development speed, assessment quality, and field usability — challenges directly tied to this had to be designed from scratch. Not just technology selection, but UX, data handling, and offline strategy: the very first design decisions determine the business value.

We want to speed up how fast new care managers master the assessment logic

Mastering the complex assessment logic of 74 items × 8 categories × the MHLW manual through classroom study alone is hard.Proficiency period drags ondoing so delays field assignment and accelerates staff shortages.

We want to eliminate transcription and scoring errors from paper survey forms

When tallying, transcribing, and scoring by hand,A few % errorsbecomes the norm. Misjudgments directly affect the certified care level — a serious risk impacting users' services and out-of-pocket costs.

We don't want veterans' judgment know-how to remain individual-dependent

Even when multiple care managers assess the same person, results vary by experience. Know-how concentrates in veterans, andlost from the organization when staff leave or transferis a serious risk to service quality.

We want to use it during training without relying on connectivity

In-facility Wi-Fi is often unstable, and in off-site training or disaster drills the network may be unavailable.Online-only tools can't be used in the field。

ARCHITECTURE

The architecture we built together

Built in-house from scratch, solving four areas at once.

Built in-house from scratch across 4 areas: a single PWA-powered SPA + an assessment engine compliant with MHLW logic + an intuitive body-map UI + result visualization. Everything runs entirely on-device, with a design that never sends users' personal data to a server — launching a platform that supports both training and field operations.

EXECUTION

Duration (months)

Total effort (person-months)

Area ①

Input UX

Challenge

Simply entering 74 items one after another has a high cognitive load, and newcomers easily drop off

Solution

8 steps × body-map UI

Visualize progress per category; enter physical-function items intuitively by clicking

Area ②

Assessment engine

Challenge

The MHLW logic is complex, and manual calculation produces variation

Solution

Client-side assessment engine

A TypeScript module compliant with MHLW logic computes instantly

Area ③

Result visualization

Challenge

If results are only numbers, trainees find it hard to learn "why this judgment was reached"

Solution

Score breakdown + graph visualization

Present confidence, distribution by care level, and score contribution in graphs

Area ④

Operations & privacy

Challenge

A network-dependent design wouldn't work in the field, and sending personal data to a server is also a risk

Solution

PWA + on-device processing

Offline support via Service Worker; all data stays on-device

IMPACT

The value the platform creates

A platform that balances care-staff development and assessment quality.

Not a single tool, butFaster talent development, standardized assessment quality, and flexible field operations — a platform that solves these simultaneously. From four perspectives — newcomer, field, facility, and management — it delivers concrete business value to each.

Accelerated proficiency

A platform where new care managers learn the assessment logic step by step through repeated practice — drastically shortening the proficiency period that classroom learning alone had prolonged.

Standardized assessment quality

Experience-based variation disappears — the same accuracy no matter who assesses, where, or when. Individual dependence is turned into organizational knowledge.

Field operation flexibility

With offline operation independent of network conditions, it becomes a "truly field-ready" tool usable during training, on business trips, and in disaster drills.

Training cost reduction from a management perspective

By reducing the frequency of group training, shortening OJT periods, and lowering veteran dependence, education costs are structurally reduced.
