CESY501 Getting Started on Product and Service Design

Course Project

The course project is designed to give you practical experience applying the tools and skills the course provides. Completion of the project is a requirement for the course. It is also an excellent way to build a detailed set of notes about how to initiate the design process. Your initial work on the course project involves sketching your design idea and identifying stakeholders relevant to your design project. In addition, you use a tool presented in the course to define the system-design context. Later, the course project invites you to analyze use-cases regarding how the product or service will be used and derive requirements from them. As a final step, you summarize the requirements. The five parts of this course project are laid out sequentially. Please complete one part of the project before proceeding to the next. Please do not submit your project for review until you have completed Part Five.



Part One

Make Your Own Sketch

1. Create an annotated product sketch to illustrate the product or service idea you have chosen. To record your sketch so that it can be submitted to your instructor, you may do any of the following:

Create the sketch on paper and scan it Create the sketch using a drawing or paint program Create the sketch using clip art with the software of your choice

Make sure your sketch includes a title and whatever annotations it may need. Otherwise, the only requirement for the sketch is that its composition be uniquely yours and that it adequately conveys your intention. Copy and paste the file into this document.

Insert sketch:



2. Describe your product or service idea. Do not write informally: use complete sentences. When you submit all five parts of your completed project at the end of the course, your instructor will compare your concept sketch to your written description of it.

HomeAlone is a wearable device, which helps patients and physicians to track vital

signs like Blood Pressure, Heart Rate, Body temperature, etc. in addition to being a

watch. This device along with a CMS (Central Monitoring System), stores all the data

supplied from the HomeAlone device. The hard drive in the CMS helps storing large

amount of data and seamlessly transmits it to the main server where physicians can log

into the HomeAlone application and monitor the patients’ vitals. CMS is connected with

a Phone Line which enables the HomeAlone device to also act as a phone. Whenever

there is an anomaly noticed in the vitals of the patients, a distress signal is sent to the

“BA Biotech Unit” where a customer service representative speaks directly to the

patients about the health. If the patient is not able to communicate about their health,

the unit will send the message for sending an Ambulance at the patient’s home. The

data is automatically transmitted from HomeAlone Device to CMS at a regular interval of

five minutes. This is the industry setting and can be reduced to a minimum of a minute

by the user. However the device restricts the user go over the 5 minute. HomeAlone

device will be powered by Lithium coin cells and CMS will be powered by the power

socket. It also has a backup battery of 9V which will last the device for 6 hours in case

of power failure. CMS also has USB ports to manually retrieve the data.

Remember to save your work for this part before going further in the course. You will encounter part 2 of the course project at the end of the next topic, "Your Stakeholders and Your Mission".



Part Two Name the Stakeholders

Before you begin work on this part of your course project, be sure you have completed the topic, "Your Stakeholders and Your Mission". Please answer the following questions:

1. Who is the owner of your design project?

BA Biotech Inc.

2. Who is the customer of your design project?

Hospitals

Physcians

Healthcare Insurance Companies

Family of patients

Patients

3. Who is the user of your design project?

Patients

Identify these individuals using the guidelines presented in this course topic. In some cases, more than one individual may fill a particular role. If there is some ambiguity, indicate how you might simplify your consideration of stakeholders and roles.

When you have completed this assignment, remember to save your work. You will encounter part 3 of the course project at the end of the next topic, "Boundary and Context".



Part Three Complete the Matrix

Before you begin work on this part of your course project, be sure you have finished the topic, "Boundary and Context".

1. Fill in the name of the system, either HomeAlone or Internet Meal Service, at the top of the matrix. 2. Fill in the names of three to five important entities in the appropriate cells in the top row. You may list the internal

entities of the system individually if you wish, or list them together as "system." If you list them individually, be sure to group them so you are able to draw the system boundary around them.

3. Fill in the names of the three to five important entities in the left-most column, going down. Be sure to use exactly the same entities in the same order you chose in step 2.

4. Draw a thick boundary around the cells of the matrix that represent the total group of the system entities. You may find that this boundary includes just one cell of the table or several. Use cell shading or border formatting to clearly indicate the cells of the matrix that represent the total group of the system entities.

5. Populate the matrix with phrases that specify the relationships between the entities. For example, to specify the relationship of entity 1 to entity 2, fill in the cell in row 2 column 3.

Notes for Filling in the Matrix

It is not necessary to specify the relationships of entities with themselves. For example, it isn't necessary to fill in row 2 column 2, because this cell would contain the relationship of entity 1 with itself.

The contents of the cells in any column X should match the contents of its counterpart, row X. For example, the contents of row 2 should match the contents of column 2, because they both represent the relationships of entity 1.

Note: You will return to complete this matrix in part 4.

Part Four Describe the Behavior and Expand the Context

Use the tables below to complete Part Four.

1. Identify one primary use-case for your design project. 2. Complete two use-case behavior tables (below) detailing two behaviors for that use-case, specifying the initial

condition of the system for each. 3. Return to the completed context matrix from Part Three of the course project and expand it, using entities you

discovered from the use-case behaviors described in the first part of this assignment.

When you have finished this assignment, please save your work to a convenient location on your computer where you can easily find it again. You will revisit this document later in the course.

Part Five Define Functional Requirements

Before you begin work on this part of your course project, be sure you have finished the topic, "Summarize and Finalize Requirements."

Step 1: List and Summarize the Functional Requirements

1. List your detailed requirements in the "Source" column of the table below. Add rows as needed. 2. Once you've created your list, identify possible groupings of two or more detailed requirements that you could

summarize to create a single more general abstract requirement. For each grouping, develop a summarized requirement that conforms to the guidelines presented in this course. You may use more or fewer groupings than appear in the table below.



3. In the table below called Originating Requirements, create a single list consisting of:

Source

The system shall switch to Vital Sign

Mode

The system shall measure

The system shall display vital sign measurements on touchscreen.

The system shall transmit the data.

The system shall display "Save Successful" and "Save Error".



Step 2: Finalize the Functional Requirements

4. Review your list of functional requirements. Are you aware of any issues that you should resolve? Do any of your requirements need to be clarified or revised in any way? In the space below, please enter the criteria you used to evaluate your requirements, and make a note of any revisions you made at this stage.

1. The system shall switch to Vital Sign Mode – This is a separate screen from the watch screen. The digital watch mode will

switch to the vital sign mode and all the vital measurements will be displayed on the watch.

2. The system shall transmit the data – There will be an icon on the watch screen which will display if the HomeAlone Watch

is connected to the CMS storage device, similar to the Bluetooth icon.

When you have finished with this document, save it with the name CESYS501_XYZ replacing XYZ with your initials. Return to the course and use the directions to submit the project to your instructor for review.
