Course Website Print answers for Sections 1 and 2 on this set of pages. Write answers to Section 3 in the provided exam booklet. Use time wisely. No additional time would be given. Section 1 [14 pts]. Answer the questions after reading the following case study: Tietroniks is a CMMI level 3 (working towards level 4) and an ISO registered company that adheres to FDA medical device regulations for custom medical software development. Tietroniks has recently successfully acquired a $15.5 million project for developing a medical software solution for a well-known client. The final product would have the following features: 1. Clinical decision support: Clinical decision support helps medical professionals avoid errors by providing them with safeguards such as checking a new prescription for drug to drug interactions and patient allergies. 2. Disease management: Disease management software provides tools for patients and/or clinicians to help monitor chronic diseases such as diabetes, congestive heart failure (CHF), hypertension, and chronic obstructive pulmonary disease (COPD). 3. Electronic medical records (EMR): An electronic medical record (EMR) system manages data about the patient, their visit, and treatments performed. It is typically used as a replacement for a paper patient chart, but often provides much more functionality such as e-prescribing and clinical decision support. 4. E-prescribing: E-prescribing software allows clinicians to send prescriptions electronically to pharmacies. It eliminates the task of trying to decipher handwritten prescriptions and typically forces the user to specify enough information so that the drug can be dispensed without a call back from the pharmacy. 5. Integration & Standards: Integration between medical software is typically done with HL7 messaging, CCD, or CDA documents. Standards such as HL7, ICD-9-CM, and SNOMED make it possible for medical software to catalog and share complex data. 6. Medical billing software: Medical billing software provides the mechanism for the clinicians to get paid for providing treatment. Often it can be built into other pieces of software such as an electronic medical record or a practice management system. 7. Medical coding software: Medical coding software provides the tools necessary to write standardized information about a patient's condition(s) and the treatment that was provided. Medical codes are often used for medical billing software to calculate the payment due by the insurer or government agency. 8. Medical scheduling software: Medical scheduling software makes it easy to schedule patients, clinicians, resources, and locations so that procedures or exams can be performed. 9. Medication Management: Medication management software focuses on how to deliver the appropriate medication(s) to patients based on their medical history, current best practices, medication list, and insurance provider. 10. Telemedicine / Connected Health: Telemedicine allows doctors to treat patients remotely (not just over the telephone). Connected health helps remotely monitor and treat patients while they go about their daily routine. Remote monitoring can be used for early intervention for problems that may not have otherwise been seen until they cause a hospitalization. Page 1 of 7

2 Medical software is a very complex area with its own set of terminology, laws, and data integration standards. Due to the critical nature of this software, providing quality while delivering on time is of utmost importance. As a project manager, you are required to devise a project plan, track time and effort against initial estimations, devise and maintain quality standards and provide all possible documentation. Deliverables of the project include complete user manuals and documentation to avoid faults. Tietroniks has also agreed to provide free support for the software for 6 months after the initial deployment and 5 years thereafter. Please answer the following questions related to this case study: a. Define (plot) the complexity of each of the 10 software features using the Boehm s complexity definition system Lower Management Complexity - Small Scale - Informal - Single stakeholder - Products Higher Technical Complexity - Embedded, real-time, distributed, faulttolerant - Custom, unprecedented, architecture reengineering - High performance Higher Management Complexity - Large Scale - Contractual - Many stake holders - Projects Lower Technical Complexity - Mostly 4GL, or component-based - Application reengineering - Interactive performance b. During system development it is sometimes beneficial to reuse Commercial Off-The-Shelf (COTS) systems. Describe TWO benefits and TWO problems that can be derived from reusing COTS. Page 2 of 7

3 c. Assuming that you decided to utilize billing COTS modules for the project in order to reduce development time, how would you integrate these into the system? d. Some features of the software are inter-dependent on others, argue why an incremental development approach is favored. e. Most development projects nowadays utilize agile development methods. Reason if using an agile method is appropriate? Page 3 of 7

4 f. V-model is used in systems engineering projects due to its quality effective and intense validation mechanisms. Reason why this approach would be effective for this project? g. Should you tailor an appropriate SDLC for this project? Explain with arguments. Section 2. [8 pts] Select the most appropriate choice and print in the box provided.
