Project Description

• Mountain View Community Hospital has on out dated
  system in place and in order to manage better
  they need to consider newer technology for
  Mountain View.
• They have put in place a special study team along
  with a consultant, that will create a system
  which would integrate data from heath plans,
  physicians, and hospital system, while providing
  real-time information.

Current Structure
4
Integrate

• Patient accounting
• Care management
• Insurance systems

5
Potential client/serverarchitecture
6
Options

• Acquire existing client server application
  packages and adapt them to MVCHs needs.
• Custom development.
• Layer the client/server applications on top of
  existing systems.
• Wait for technology improvements.

Question 1

• Why are some of the possibilities for processing
  and providing information that could arise if
  MVCH were to move to a client/server environment?

8
Answer

• In building its own custom client/server system,
  the short-term costs may be higher. This would
  include acquiring advanced tools, the expenses of
  training users and the set up time. Since it is
  not possible to know at the time when the
  decision is made to adopt, the final product may
  not look like the expected outcome. With the
  existing hardware and software this may be the
  best scenario since it offers better
  interoperability.

Project Question 2

• What are some of the possibilities for processing
  and providing information that could arise if
  Mountain View were to move to a client/server
  environment?

10
Question 2 Answer

• The system will integrate all data data from
  health plans, physician, and hospital systems so
  that accurate real time information will be
  available. all this implies that the scope of
  the system under consideration is very broad.
• The general system requirements include
  availability of real time and accurate
  information. Also, an attempt would be made to
  integrate Mountain Views present accounting,
  care management and insurance systems.

11
Question 2 Answer Cont.

• Our first alternative is the consideration of a
  files server system, where all data manipulation
  would be used at the clients Personal Computers.
  Since the client workstation does most of the
  work, each client must be powerful to provide
  good response time. The DBMS copy in each
  workstation must mange the shared database
  integrity.
• With the database server architecture, the only
  database server requires processing enough power
  to handle the database and the database is stored
  on the server, not on the clients. The database
  server can be tuned to optimized database
  processing performance.

12
Question 2 Answer

• Since less data is sent across the LAN, the
  communication load is reduce. User authorization,
  integrity checking, and update processing are all
  performed in one location, on the database
  server.
• Data integrity can be improved as multiple
  applications access the same stored procedure.
  However, writing stored producers take s more
  time than using Visual Basic or powerbulider to
  create an application. This reduces their
  portability , and may make it difficult to change
  DBMS.

13
Question 2 Answer

• Parallel processing, however could help Mountain
  View to remain centralized on an application or
  database server.
• If one of the requirements is to have available
  accurate real-time information, the multi-tier
  model would make sense. It is suitable for
  environments of more than 100 concurrent users.

14
Project Exercise 1

• In exercise one it wants you to outline the pros
  and cons of the four approaches to moving to a
  client/server environment
• 4 environments are
• Customizing off the shelf systems.
• Custom system development
• Surrounding and layering
• Doing Nothing for a while

15
Customizing off the shelf systems

• Pros
• The Product can be seen before implementation.
• Beta testing available
• Quicker implementation. Leading to improved
  productivity
• Cost estimates are closer to the actual expense.

16
Customizing off the shelf systems

• Cons
• Competitors can purchase the same product, and
  this will neutralize the expected competitive
  advantage
• Interoperability with existing hardware and
  software needs to be considered.

17
Custom System Development

• Tailored to meet all the business specific needs
• Competitive advantage
• Needs a project team
• Additional hidden cost may occur
• Hard to estimate the actually deadline
• Better interoperability with the existing
  hardware and software

18
Surrounding and Layering

• Possible to further utilize the existing
  mainframe system.

19
Project Exercise 2

• Using the list developed in the first project
  exercise, indicate which solution MVCH should
  try. Also, indicate what additional information
  you would like to have to help you with your
  recommendation.

20
Project Exercise 2 Answer

• The recommendations may be based on the points
  suggested in the question above.

21
Project Exercise 3

• Try to get some material about the off the shelf
  client/server hospital systems, such as Surginet,
  Aviion, and Cycare. Investigate the capabilities
  of each system, the number of installations, the
  client operating system used, and so on.
  Determine which of the systems you have found and
  learned about might be of interest of Mountain
  View.

22
Project Exercise 3 Answer

• Surginet
• The surgery department is a major cost and
  revenue generating center. Management of all of
  its resources and the monitoring of utilization
  practices provides a significant opportunity to
  contribute positively to the financial management
  and quality assurance aspects of a healthcare
  organizations.

23
Continued

• Aviion
• provides integration and professional services
  to over 3500 hospitals worldwide. It provides
  customized services that are unique with each
  hospital, and has a strategic alliance with
  Microsofts healthcare industry and the Intel
  Corporation.

24
Continued

• Cycare
• Cycare systems provides information systems,
  related support services and electronic data
  interchange services to the healthcare industry.

25
Joes Question

• List the four advantages and describe any 2 of
  the four approaches that MVCH has for moving a
  client/server environment.

26
The Four Approaches

• Customizing off the shelf system
• Custom system development
• Surrounding and Layering
• Doing Nothing for a while

27
Jamess Question

• There are 3 systems that MVCH might use.
