DocCare is a portfolio product concept — designed and documented by Kaizen Labs as a case study. It was not built for a client.

The Problem
Booking a doctor should not require a phone call.
Appointment booking is a workflow every patient recognises: find the right doctor, check availability, book a slot, and manage changes when plans shift. Done over phone calls and registers, it creates friction for patients and administrative load for clinics.
This concept explores how that everyday workflow can be turned into a structured, development-ready digital product — starting not with screens, but with business requirements, rules and user journeys.
Approach
From idea to working demo
01
Discover
Framed the core problem: patients need a simple way to find a doctor and book an appointment without phone calls or front-desk queues.
02
Analyse
Mapped the appointment workflow end to end — search, availability, booking, rescheduling, cancellation and notifications — along with the business rules behind each step.
03
Define
Documented the product scope, user journeys and product requirements (PRD) for patients and doctors.
04
Structure
Broke the requirements into user stories with acceptance criteria and a prioritised product backlog.
05
Build
Developed the working application demo directly from the structured requirements and backlog.
06
Validate
Prepared UAT scenarios and validated the delivered flows against the documented requirements.

Documentation Excerpts
A look at the actual artifacts
Examples from the concept's own documentation — the kind of development-ready material every Kaizen Labs engagement is structured around.
Business rules — excerpt
- BR-01A patient cannot hold two confirmed appointments with the same doctor at overlapping times.
- BR-02A time slot becomes unavailable to other patients the moment a booking is confirmed.
- BR-03Rescheduling releases the original slot immediately and is subject to the doctor's current availability.
- BR-04Cancellations trigger a notification and return the slot to the doctor's available pool.
Sample user story
“As a patient, I want to see a doctor's available time slots for a chosen date, so that I can book an appointment at a time that suits me.”
Acceptance criteria
- Given a doctor profile, when I select a date, then I see all available slots for that date.
- Slots that are already booked are shown as unavailable and cannot be selected.
- On confirming a slot, I receive a booking confirmation with the doctor, date and time.
