Capstone Case: New Century Wellness Group
Task 1: Financial Overview Of The Proposed System
The cost and benefit data of an organization is considered a significant step as these
economic factors affect directly the future development and feasibility of the new system.
Below an analysis has been shown that will explain that every individual company has its
way of calculating the costs and the benefits where some of the techniques are more
conservative than the other technique. For example, there are companies who don’t count
their saving till the time there is an actual need for a reduction in out-of-pocket expenses.
Whereas, in other companies, the saved hours present a valuable resource that can be
accounted and identified for – as well as it is the job of the management to see that the
possible savings on the cost are achieved by performing more tasks, and better-quality
work, and other work.
Below a sample analysis has been presented that outlines the tangible costs as well as
benefits which are addressed in the background of Chapter 7. Later by using the below table
data an analytical spreadsheet will be created that will present the feasibility analysis in
detail.
Costs and Benefits
Economic Effects
Cost and Benefit Categories
2. Eliminating 3 hours of overtime every week at 15 dollars per hour
6 hours (Annual Saving) * Hourly rate $15 * 52 weeks * overtime factor of 1.5 = 7020 (6
impact months or 3510 dollars will be available in every Year 0)
Variable, positive benefit, operational, direct
Removing the errors that occur daily
1 hour per day of possible annual savings = 52 weeks * 5 days * hourly rate of $15 * 1 =
3900 dollars (6 impact months or 1950 dollars will be available in every Year 0)
Variable, positive benefit, operational, direct
Time required by a consultant to develop the system – in-house option
75 dollars hourly rate * 40 hours * 20 weeks = $60000
Fixed cost, development, direct
Removing the requirement of additional position in 6 months
3. 40 hours (Avoidance annual cost) * hourly rate $15 * 52 weeks = 31200 dollars (6 impact
months or 15600 dollars will be available in every Year 0)
Variable, cost avoidance benefit, operational, direct
Network commercial database software – in-house option
4200 dollars
Fixed cost, development, direct
The vertical software package from the vendor – package option
$28000 in Year 0 is followed by 2 annual payments of $23500 for a total of $67000
Fixed cost, development, direct
Time to install, configure, and then test the vendor package by the consultant – package
option
4. $75 hourly rate * 40 hours * 2 weeks = 6000 dollars
Fixed cost, development, direct
Vendor technical support – package option
The annual cost of $2000 after the 1st operation completion year
Fixed cost, development, direct
Time required by the staff of the clinic to perform file backups, updating, and maintenance
4 hours annual cost * 52 weeks * 15 dollars hourly rate = 3120 dollars (6 cost impact
months or 1560 dollars will be acquired during every Year 0)
Fixed cost, development, direct
Time required by a consultant to provide starting support and training
$75 hourly rate * 13 weeks * 10 hours = 9750 dollars
5. Fixed cost, development, direct
Hardware requirements
8500 dollars
Fixed cost, development, direct

Task 3: Various Alternatives
In-House Development Of Software
Build up the in-house potentials and assets
Meet all the limitations of the technology and system presented
Decrease the alteration in the strategies and dealings of the company
Assure the distinctive necessity of the company
Purchase Of A Package Of Software From The Vendor
Reduce the overall cost
Shorten the time required for implementation
Reliable in benchmark performing
Vendor provides the future upgrades
The requirement for technical staff will be less
Vendor Supplied Package Customization
Modification can be possible by oneself after the software is purchased if the license is
available.
Users can make the software purchase that is customizable by the vendor according to the
requirements of the user.
Negotiation becomes possible and easier with the software of the vendor and requires
payment for the features that are required.

Task 1: Storyboards And Wireframe Design
First, the login screen of the system is required that will allow the user to provide their
credentials into the input area and click on sign in to log in. Below the four screens designs
of the application have been shown then depending on which user will log in to the system
the option will vary as follows:
For a doctor or a Nurse
For a receptionist
According to the above picture, it has been cleared that the nurse/receptionist/doctor has
several options that they see in the main menu of the application. Below some of the
wireframe designs are provided by using the tool “Balsamiq” that will show if the employee
(nurse/receptionist/doctor) wants to see the details of the patient then what they will be
going to see.
After choosing the Change/View Schedule Appointment option from the menu list, this is
what the current user will be able to see:
Also, when scheduling an appointment for the patient to get done the information which is
provided will be sent to the calendar that can be accessed from the initial page. Below the
wireframe design of the calendar page has been shown:
If the user chooses the option “View Email” from the main page then for the employee there
will be a specific page that will open that will be the email page with a simple interface.
Below the design of the email page has been shown:
Task 2: Data Required For The New Patient

Task 3: Validation And Control Features
Control Features
Display the event-driven reminders and messages
Establish a series of values that will be predefined that the user can click in order to start.
Other control features are such as the toolbar, menu bar, command button, text box, check
box, and so on.
Validation Features
Filling the form online with instant validation will save time at the office. It will be useful for
the receptionist as well as for the client.
12. Proper validation and input masks will make it easier in order to interpret the format of the
data as well as enhance the entire integrity of the data.
Output security to protect the privacy right of the users from unauthorized access as well as
restrict the printed copies as well as remove the document properly.
Consistent control of the documents such as providing the page number on all the
documents as well as the document will be printed.

Task 1: Logical Diagram
Below the logical design of the database that will be going to be developed later has been
shown. In the design, all the essential entities are highlighted which will be responsible for
storing the information. Here, for the design pre-defined symbols are used such as the
rectangle denoting the entities, the diamond denoting the relationships between the two
entities, and the connecting establishing the connection between the two entities. In logical
design, only the logic is mentioned no specific cardinalities or constraints are used.

Task 2: Relationship Between The Entities
The below design is the detailed version of the logical design where the difference is the
presence of cardinalities which helps to determine how the data will flow between the two
entities and how the user will fetch them. This diagram will help to make the appropriate
decision in the business and based on all of these things the relational design is created.

Task 3: Verification Of Primary And Foreign Keys
For the verification of the designs of all the tables created it is important to ensure that
there are no data redundancy and all the tables are normalized. Below the normalized
relations are provided:
