What is the main purpose of the Systems Design phase?
The main purpose is to decide how to approach system development. Namely to choose bewteen build or buy. Once the build or buy decision has been finalized, system design will either follow the internal development path or focus on vendor solutions
What part of SDLC is Systems Design?
Second phase of SDLC.
Does Systems Design consider build vs buy decisions?
Yes, that is one of the main focuses of systems design, as it determines "How" to approach providing a solution, either by building it or rather by purchasing it.
What are some goals of Systems Design?
1. Make technical specifications
2. Choose Build or Buy
3. Ensure solution supports business needs
4. Minimize compatibility/integration issues.
5. Develop RFI/RFP if needed.
6. Identify dependent subsystems.
7. Design data management practices.
8. Ensuring user acceptance through training and education
Who is part of the systems design team?
Systems Analysts
Systems Developers
Design Leads
RFP Committee
Project Managers
Domain Experts
Who does the design team primarily interact with?
1. End-Users
2. Systems Analysts
3. RFP Committee (if choosing to buy solution)
What are the Deliverables and Tools of the systems design phase?
1. Technical specification documents

2. Systems design document

3. Security risk assessment

4. Conversion and Integration plan

5. Training Plan

6. Prototypes and mock-ups
What is the Technical Specifications Document?
It is a direct translation of users functional requirements in to technical requirements to satisfy those functions.
What is the Security Risk Assessment?
It defines what the security setup should be for networking, exchanging data.
What is the Conversion and Integration Plan?
It contains software, hardware and networking compatibility information with other systems and sub-systems within the organization. It also contains info about an Interface.
What are Prototypes and Mock-Ups?
Creating a prototype or mock-up of the solution to demonstrate what the solution will look and feel like.
What primary Tool or Diagramming technique is used in Systems Design phase?
UML - Unified Modeling Language is used to create diagrams, flowcharts, etc to describe the system. UML is a way to translate functional requirements from the systems analysis phase in to Systems Design technical documentation.
What is the Systems Design Document?
It primarily deals with internal development of the solution. It describes Inputs, Outputs, data specifications, the programming specifications and had flow charts (process, data, activity)...etc.
What is a Training Plan?
It determines how to and what to train the end-users and super-users. How training will be carried out, such schemes as train the trainer, big training sessions, self-study training, etc.
What is the definition of a Business Process?
It is a series of tasks to solve one problem.
What are Operational Processes in healthcare?
They are a set of activities involved in delivering patient care, ultimately translating into the revenue stream.
What are Supporting Processes?
Tasks which support Operational Processes.
What is important about Business Needs?
Analysts should be able to translate them into Functional Requirements, eventually leaving to technical specifications for a new system to be either created or purchased.
What is important about System Integration and Compatiblity?
To make sure the proposed system can communicate with existing systems. The software, hardware, networking, data exchange formats provided by new system should be compatible with existing systems.
What does ICD-9 or ICD-10 stand for?
International Classification of Disease version 9 or 10 (this is currently under development).
What does HL7 stand for?
Health Level 7
What does XML stand for?
Extensible Markup Language
What does IHE stand for and what is it?
IHE = Integrating Healthcare Environment. It is an initiative to establish standards and advance interoperability in the healthcare IT infrastructure.
What are the 3 broad areas of compliance as they relate ot healthcare IT?
1. Healthcare industry compliance
2. Regulatory compliance
3. Organizational compliance
What is an RFQ?
Request for Quote, which contains basic financial/cost data from the vendor to the requesting organization.
What is TCO?
Total Cost of Ownership. It explains to the purchasing organization how much it will cost to own a certain system.
Should the RFP have questions setup for binary answers or narrative answers?
Binary answers, so that they can be compared between vendors and scored easily.
What does EUDPD stand for and what is it?
European Union Data Privacy Directive.
What does HIPAA stand for and what is it?
Health Insurance Portability and Accountability Act. It sets limits on patient care data as to whom and how it is shared.
What does RHIO stand for and what is it?
Regional Health Information Organization and it allows physicians/clinicians from several different organizations to access data from other organizations.
What is a DRP and what is it?
Disaster Recovery Plan, which describes in detail how data access will be restored after a disaster.
What are some examples of standards based data formats?
What is the difference between a datal protocol and data a standard?
A data standard defines how data is stored. Protocol refers to the method by which systems transfer data to another system
What are some examples of data protocols?
The development of the request for proposal occurs during which systems lifecycle stage?

A. analysis
B. design
C. development
D. management

The systems analysis stage defines the functional requirements that the request for proposal (RFP) attempts to solve. Systems design is charged with initiating the RFP process after deciding to acquire a vendor system. The design team is also responsible for interpreting the vendor's technical specifications. The systems development stage involves the actual programming of the system based on the technical specifications document. A management stage is not part of the system developments life cycle.
A private hospital listed computerized practitioner order entry as part of its strategic vision. The hospital currently maintains a mixture of best-of-breed clinical systems. The most common system design approach for an organization with these requirements is to

A. insource development and outsource implementation
B. outsource development and insource implementation
C. acquire a pre-developed system and insource system analysis
D. acquire a pre-developed system and outsource system analysis

Most private hospitals do not have the development resources to insource the development stage. Outsourcing development is common among vendors, not hospitals. The most common design approach for hospitals is to purchase a vendor (pre-packaged system).
Which of the following deliverables is outside the scope of systems design?

A. request for proposal
B. request for information
C. functional requirements document
D. technical specifications document

The request for information (RFI) and request for proposal (RFP) both fall under the scope of systems design. The functional requirements document is created during systems analysis. The technical specifications document is created during systems design.
Which of the following flowchart representation standards to system design diagrams follow?

A. unique modeling locator
B. unique resource locator
C. unique modeling language
D. unique resource lanuage?
C. Unique Modeling Language

Systems design flowcharts are typically represented in UML: Unique Modeling Language. A unique resource locator or URL is used for website addresses.
During the implementation phase of a cardiac imaging system, the project manager learns that a critical license is preventing data exchnage between the new system and the institutional PACS. After contacting both vendors, the manager discovers that an additional license must be purchased from the PACS vendor at full list price. The cost of the license sends the project over budget and delays implementation. Which system design deliverable could have prevented this oversight?

A. exchange server
B. interface engine
C. protocol diagram
D. database dictionary
C. protocol diagram

A protocol diagram would have displayed the data workflow between the two systems, prompting an evaluation of dependent sub-systems and their licensing requirements. An "Exchange server" is an enterprise email product from Microsoft. An interface engine is not a design deliverable; it is a fully developed software program that transfers healthcare data between systems. A database dictionary is used for reporting and building queries against a database. Vendors typically provide access to database dictionaries based on non disclosure agreements, not licenses.
