Case studies, the way a BA actually works.

Each case walks you through a real-world problem: who's involved, what they need, what the requirements look like, and the simple flow that ties it together. Then you make decisions and draft a requirement — and compare your answer to a worked exemplar.

Reducing No-Shows at a Community Clinic

A 12-physician clinic loses an estimated $480k/year to patient no-shows. Leadership wants a low-risk, low-cost intervention before investing in a new EHR.

Problem statement

Patient no-show rate has risen from 9% to 17% over 18 months. Front-desk staff manually call to remind patients but only reach ~40% of them. The clinic needs to lower no-shows without hiring additional staff or replacing the existing scheduling system.

Context & constraints

The clinic uses an older scheduling system that exposes a REST API for appointment data. Patients skew older (avg. 58) but 86% have a mobile phone capable of SMS. HIPAA constraints apply: appointment details cannot be sent to a phone number that has not been verified as belonging to the patient.

What they need

User needs

  • 01

    Patients want a reminder a day before, with one tap to confirm or reschedule.

  • 02

    Front-desk staff want to focus calls on high-risk patients only.

  • 03

    The Operations Director wants weekly visibility into no-show rate by physician and slot type.

  • 04

    Compliance needs an auditable opt-in record for SMS communications.

Written for the ECBA

Sample requirements

BR-1Business

Reduce overall no-show rate from 17% to ≤10% within 6 months of launch.

Rationale: Aligns with the sponsor's revenue-recovery target of ~$280k/year.

SR-1Stakeholder

As a patient, I want to confirm or reschedule my appointment with one tap from a text message.

Rationale: Captures the convenience need that drives confirmation rate.

FR-1Functional

The system shall send an SMS reminder 24 hours before each scheduled appointment to patients who have a verified mobile number and active SMS opt-in.

Rationale: Operationalises the reminder need within HIPAA constraints.

FR-2Functional

The system shall allow the patient to confirm, cancel, or request a reschedule via reply codes (C, X, R).

Rationale: Supports the one-tap interaction without a smartphone app.

NFR-1Non-Functional

All patient SMS communications shall be logged with timestamp, opt-in status, and message body, retained for 6 years.

Rationale: Compliance and audit requirement.

TR-1Transition

During a 4-week pilot, the system shall run alongside manual reminder calls; manual calls shall be retired only after no-show rate is verified ≤12%.

Rationale: Reduces operational risk during cutover.

How it runs

Process flow

  1. 1
    Scheduling system
    Publishes appointments for the next 48 hours via API.
  2. 2
    Reminder service
    Filters to patients with verified phone + SMS opt-in.
  3. 3
    Reminder service
    Sends SMS 24h before appointment.
  4. 4
    Patient
    Replies C (confirm), X (cancel), or R (reschedule).
  5. 5
    Reminder service
    Updates appointment status; routes R replies to a callback queue.
  6. 6
    Front desk
    Calls only the callback queue and unreached high-risk patients.
