New Century Wellness Group
New Century Wellness Group offers a holistic approach to healthcare with an emphasis on preventive
medicine as well as traditional medical care. In your role as an IT consultant, you will help New Century
develop a new information system.
Background
New Century Wellness Group is interested in a new information system to support its business and health
information management needs. The new system would replace a mix of paper-based and fragmented
computer systems. Dr. Jones had previously asked you to work with him as a systems analyst and help the
group develop an information system that will support current operations and future growth. You will
explore the possibility of a business support system for the scheduling, billing, accounting, and payroll
functions of the practice as well as a system to support the clinical applications of Electronic Medical
Records (EMR), Computerized Provider Order Entry (CPOE), and a Clinical Decision Support System
(CDSS).
At your next meeting, Dr. Jones explains what the practice partners have in mind in more detail. They are
looking for a medical practice software solution that allows each office worker to conduct their job more
efficiently. He explains to you what systems they are looking for from the perspective of a patient who
comes into the office.
Lisa Sung schedules a patient’s appointment and the patient comes into the office for the first time. On
this appointment, an EMR is started for the patient that includes the patient’s demographic information,
medical history, and insurance information. A patient may be coming in to see any one of the healthcare
providers, including a physician, nurse practitioner, physical therapists, or the nutritionist. These providers
would enter any orders or prescriptions into the EMR with the CPOE system. The Providers who use the
EMR and CPOE system are supported by the CDSS. Patients often schedule a follow-up appointment
before leaving the practice office.
After a patient’s visit, Susan Gifford, who maintains the patient medical records, reviews the records to
ensure they are complete. Carla Herrera orders any supplies needed to replace items used by the patient.
Tammy Alipio begins billing the patient’s insurance provider for services that were rendered to the
patient. Tom Capaletti follows up on the billing to ensure the practice is getting paid for all claims. Dr.
Jones also tells you that the system should also include modules to support Fred Brown and Corinne
Summers in HR and payroll. You explain to Dr. Jones that you would like to conduct a preliminary
investigation that will give you the information you need to make recommendations about what system
they should pursue. Dr. Jones agrees to your investigation and you set a follow-up appointment in one
month.

1. Provide one sample questions to determine whether a project has technical feasibility.
2. Provide one sample questions to determine whether a project has operational feasibility.
3. Provide one sample questions to determine whether a project has economic feasibility.
