U4 Practice PT – Decision Maker App Planning Guide
Project Description
For this project you will create an app that helps a user make a decision. Your app must take in at least one number
and one string from the user that will help to make the decision. All of this information will be used as part of the
decision making process. In addition, your code must include at least one function used to update the screen.
You will submit
● Your final app
● This completed project-planning guide
App Requirements
● At least one number and one string used to make and report a decision with a conditional statement
● A function which updates the screen and is called at least twice in the program
● Conditional statement includes at least one logical operator (​&&, || ​or​ !​)
● There are at least three different possible output answers (i.e. “Yes, you can adopt a cat!”, “No, you can’t adopt
a cat”, and “Congratulations, you can adopt a kitten!).
● Every function contains a comment explaining purpose and functionality
● Clear and easy to navigate user interface
● Cleanly written code which is free of errors

Brainstorm an app idea for making a decision
Interview classmates for ideas on what information would be needed to make the decision
Draft a flowchart of the decision making process
Design your app’s user interface
Design and program your app in App Lab
Collect feedback from your classmates and update your app
Submit your final app
Investigate
Step 1. Brainstorm App Ideas: ​Your app should be designed to help a user make a decision. The decision can be
small or big, like what to eat for lunch or where to apply for a job.
Idea 1:
_________________________________________________________________________________________
Idea 2:
_________________________________________________________________________________________
Idea 3:
_________________________________________________________________________________________
Step 2. Choose One Idea: ​Talk through your ideas with a classmate. Pick the one that you are most interested in.
App Idea: _________________________________________________________________________________
Step 3. Survey Your Classmates: ​To design your app you’ll need to understand your users. For this project your user
is your classmates, and you’ll need to understand what information will be needed to make the decision.
Find two classmates and talk to them about your topic for a couple minutes. Then fill in this table.
Name
What information is needed to make this decision?
Step 4: Storing information: ​What variables will be used to store information?
Name
Information Stored
Variable Type (string, number, Boolean)
Ex: age
The age of the user
number
Step 5: Flowchart: ​Draft a flowchart to show the decision making process
Example:
2
Component
Purpose
Start your flowchart with a question. What decision are you trying to make?
Baggies are used to represent the variables​ ​which store information. In your flowchart,
draw a small rectangle for the variables.
A diamond represents a decision point, based on the original question. Write the
Boolean expression that will be used to determine the answer.
True and False arrows designate the paths taken, based on the result of a decision
(diamond). Note that every decision may have only 2 possible paths that result from it,
one for true and one for false.
A rectangle at the end of a decision path represents a possible result.
A ​simple arrow ​indicates that we are moving from one action to the next without
considering any decision. These will generally be used to link a set of actions to be
completed one after the other.

Design
Step 6. Design User Interface: ​In the space below draw a rough sketch of your user interface. This means you should
include all the buttons, text, and images that the user will be able to use. Write notes or draw arrows showing how
different user interface elements should work.
Note: There are no screen requirements for this app – you may use one or more screens.
Prototype
Step 7. Start Building Your App: ​Build your app. Along the way make sure you:
● Use the design you drew as a starting point, but it’s OK to update as you go.
● Reference the flow chart when setting up your conditional statements
● Use your debugging skills to check that your app is working
● Comment all functions explaining purpose (what does it do) and functionality (how does it work)
Test
Step 8. Testing: ​You will need to test your app to make sure it works as expected. To do that find at least two
classmates to use your app. While they use the app watch them to see if anything is broken or confusing. Afterwards
ask them to share any specific improvements they’d like to see.
Name
Things that could be improved based on
watching them use the app
Improvements this person recommends
4
Step 9. Pick Improvements: ​Pick at least one improvement you plan to make to your app based on feedback you
collected from your classmate.
Improvement 1:
___________________________________________________________________________________
Improvement 2 (Optional):
___________________________________________________________________________________
Step 10: Complete Your App: ​Finish your app!
Reflection
Question 1:​ Provide a written response that:
● describes the overall purpose of the program
● describes the functionality of your app
● describes the input and outputs of your app
(Approx 150 words)
Question 2: ​This project was created using a development process that required you to incorporate the
ideas of your partner and feedback from your classmates. Provide a written response that describes one
part of your app that was improved through input from EITHER your partner or feedback you received from
classmates. Include:
● Who specifically provided the idea or recommendation
● What their idea or recommendation was
● The specific change you made to your app’s user interface or functionality in response to the
recommendation
● How you believe this change improved your app
