Case Study Scenario: Smart Hospital Modernization
A large hospital wants to modernize its IT systems to improve patient care and
operational efficiency. Currently:

Patients must register separately for laboratory tests, consultations, and
pharmacy services.

Medical records are stored in different departmental databases, leading to
duplicate and inconsistent information.

Staff scheduling and inventory management are handled manually, causing
frequent errors.

Security and compliance with healthcare regulations (HIPAA/DOH standards)
are becoming increasingly difficult to maintain.
The hospital envisions a Unified Patient Care System (UPCS) that will:

Provide single patient registration and ID across all hospital services.

Centralize patient records for real-time access by authorized doctors, nurses, and
pharmacists.

Automate scheduling of staff and allocation of resources.

Use secure cloud hosting with compliance tracking and redundancy.
To achieve this, the hospital considers using TOGAF ADM for step-by-step
implementation and Zachman Framework to ensure no perspective is overlooked.

Instructions:
Read the case carefully and answer each section. Relate your responses to the TOGAF
ADM phases and the Zachman Framework perspectives. Provide thoughtful and wellstructured answers.
Part I – Problem Analysis
1. What are the main issues with the hospital’s current IT system?
Answer:
Right now, the hospital’s technology is fragmented. Patients have to register
separately for lab tests, doctor consultations, and pharmacy services, which
wastes time and frustrates everyone involved. Each department keeps its own
database of medical records, so the same information is often duplicated and
sometimes inconsistent, making it hard for staff to trust the data. Also, staff
scheduling and inventory tracking are still done by hand, which leads to
frequent mistakes and delays. Because everything is scattered, keeping up with
HIPAA and local Department of Health privacy requirements has also become a
serious challenge.
2. Why is modernization necessary in terms of efficiency, integration, and
compliance?
Answer:
Modernization is critical if the hospital wants to operate efficiently and safely. A
unified system would remove duplicate data entry and give doctors, nurses, and
pharmacists instant access to accurate records. Integrated applications would
make collaboration between departments seamless, while automated
scheduling would reduce human error. Most importantly, moving to a modern,
secure platform would make it far easier to meet HIPAA and DOH compliance
standards and to protect patient privacy.
Part II – TOGAF Application
3. Define the Vision for the hospital’s modernization project.
Answer:
The hospital’s vision is to make things simpler and safer for everyone. We want to
create a single, connected system where a patient only has to check in once, and
all their doctors, nurses, and staff have the right information at the right time. This
means no more repeating your story or filling out the same forms multiple times. It’s
about giving our staff the tools to provide the best possible care without
unnecessary delays.
4. In Business Architecture, identify at least two processes that must be redesigned.
Answer:
First is the entire patient journey, from registration to lab work, consultation,
pharmacy, and billing, so that a patient registers once and that information flows
everywhere it’s needed. Second is staff scheduling, which should be automated to
match doctors, nurses, and equipment to demand without the current manual
guesswork.
5. In Data Architecture, explain how patient records should be managed to ensure
accuracy and security.
Answer:
All patient records should live in a single electronic medical record or EMR system
that uses strong encryption both in transit and at rest. Role-based access would
ensure that only authorized personnel can view or update records, and every
change should be logged automatically to satisfy HIPAA and DOH auditing
requirements.
6. In Application Architecture, list the key hospital systems that should be
integrated.
Answer:

The main patient administration system (for registration and billing).

The digital medical records system (where patient charts and history are stored).

The lab's computer system (where test orders and results are managed).

The pharmacy's management system (for prescribing and dispensing
medication).

The staff scheduling and inventory applications.
7. In Technology Architecture, describe the infrastructure needed for secure,
scalable operations.
Answer:
A reliable and secure internet-based system to host everything is needed. This would
include backups in separate locations to keep things running even if one site has a
problem. Inside the hospital, we need fast and secure wifi and networks so staff can
access information instantly from any department. Most importantly, we'd use a
secure login system (like the ones banks use) to make sure only the right people can
access sensitive patient information.
8. Suggest a Migration Plan for transitioning from legacy hospital systems.
Answer:
The hospital should take a careful, step-by-step approach. First, they should review
all the existing data to make sure it's clean and correct. Then, they should start small
by testing the new system in just one area, like the lab. Once it works well there, they
should gradually introduce it to other departments, making sure to train and support
our staff every step of the way. They should only turn off the old systems once
everyone is comfortable and confident with the new way of working.
Part III – Zachman Framework Mapping
9. Fill in the table below based on the hospital scenario:
Zachman Perspective Example in Smart Hospital
What (Data)
Patient details, medical histories, test results, prescriptions, staff
schedules, supply lists
How (Function)
Registering patients once for all services, booking
appointments, updating medical notes, tracking medicines
and equipment
Where (Network)
Hospital buildings, nurses’ stations, doctors’ offices, storage
rooms, and the secure online system the hospital uses
Who (People)
Patients, doctors, nurses, pharmacists, receptionists, and
hospital managers
When (Time)
Appointment times, visiting hours, staff shifts, medicine
schedules, and regular system backups
Why (Motivation)
To give patients better care, reduce mistakes, save time, and
meet health and privacy rules
Part IV – Reflection
10. How does using TOGAF and Zachman together ensure the hospital’s
modernization project is both complete and executable?
Answer:
TOGAF gives the hospital a clear, step-by-step roadmap, from setting the vision
through building each architecture layer and finally migrating off the old systems, so
the project can actually be implemented. Zachman complements that by making
sure no perspective is forgotten like data, processes, locations, people, timing, and
the reasons behind it all are accounted for. Together they provide both the “how to
do it” and the “make sure we didn’t miss anything.”
11. Compare the hospital scenario with another sector (e.g., university, airport,
bank). What lessons are universally applicable across organizations?
Answer:
This hospital's situation is common everywhere. Think of a university trying to link its
class, grade, and payment systems, or an airport syncing flights with baggage and
security. The universal lesson is that all large organizations need to connect their
separate departments, keep data safe, follow the rules, and make changes slowly.
This careful process prevents confusion and ensures everything keeps running
smoothly for the people they serve.
