3 Executive Summary We are designing an application called Kitchen Buddy. This application is meant to keep an up- to- date inventory, but in a fairly unique way compared to most applications already out there. The purpose is to be able to gradually build up an accurate inventory database of all the household items the user might purchase. Upon downloading the application, and using it for the first time, the user will scan items with their phones barcode scanner to add the item to the database. Since most people buy the same items over and over again the scanning step will only need to occur the very first time a user purchases that product. If the user runs out of an item then they will simply open the application and change the items status using minus sign to alter the quantity. When an item is marked down to zero the application will automatically transfer it to the user s grocery list when the user chooses the "shopping list" feature. After purchasing the out of stock item from the store the user can once again change the quantity of the item using the plus sign, therefore eliminating the need to rescan the products barcode. This application is designed for anyone that is charged with the task of grocery shopping in their home. The application will appeal more towards those individuals living in a busy household having to keep track of a lot of different grocery items. Therefore, the application will make it easier for the user to know exactly what he/she has in stock at all times. Our application will solve the problem of having to keep track of everything a person might have in their house at all times. The application will also solve the frustrating problem of forgetting your shopping list at home or not remembering to put something on the list. After the initial setup of scanning in the items purchased, this application will make it very easy and simple to know what you have in your pantry at any given moment. Gone are the days where you stare into your fridge or pantry wondering what you have behind all of those cereal boxes or milk jugs. With Kitchen Buddy you can just open an application, and have your entire inventory right at the tip of your fingers. 3

10 USE CASE NAME: PRIMARY BUSINESS ACTOR: OTHER PARTICIPATING ACTORS: DESCRIPTION: PRE- CONDITION: TRIGGER: TYPICAL COURSE OF EVENTS: Use Case Narratives Scanning Items Application User Product Barcode Database This process occurs when the user purchases a new item and wishes to add it to their application. The party scanning the items must have application downloaded. User selects scan barcode on Home screen. This activates mechanism (on the phones) that scans the barcode and sends it to the system. Actor Action System Response Step 1: User selects scan barcode on Home screen. This activates mechanism (on the phones) that scans the barcode and sends it to the system. Step 2: The system receives the barcode image. Step 3: The system sends the barcode to the Product Barcode Database Step 4: The Product Barcode Database sends back to the identification of the product. Step 5: The system receives the information about the production Step 6: The system updates the database with product information ALTERNATE COURSES: Alt- Step 1: If the barcode could not be scanned, the user is notified of the discrepancy and prompted to resubmit. Alt- Step 4: If the Product Barcode Database doesn t have any information to return, notify the user of the error in scanning. CONCLUSION: The database is updated with the product information 10

11 POST- CONDITION: The new information is available on the inventory list BUSINESS RULES Follow conventions for product barcodes The database will update the inventory number for the scanned item by 1 CONTRAINTS AND SPECIFICATIONS ASSUMPTIONS: N/A N/A OPEN ISSUES: Need to determine how the user can activate the use case by pushing the scan barcode button, but doesn t have a product barcode available for scanning. CORRESPONDING FORMS AND REPORTS: Home Screen. USE CASE NAME: PRIMARY BUSINESS ACTOR: Updating Inventory Database Application User OTHER PARTICIPATING ACTORS: DESCRIPTION: PRE- CONDITION: TRIGGER: This process occurs when the user runs out of an item in their inventory and needs to change the status of the item using a plus or a minus to increase or decrease the stock. This process also occurs when the user scans in a new item into his or her inventory. The item must have previously been scanned into the inventory The user selects My Inventory on the home page. TYPICAL COURSE Actor Action System Response OF EVENTS: Step 1: The user selects My Inventory on the home page. Step 2: The system receives the request and sends an inventory request to the database. Step 3: The database returns all inventory items and the number of 11

12 items available. Step 4: The system formats this information into a list and return the Update Inventory screen to the user Step 5: The user selects an inventory item and either selects the + sign (if adding an item of inventory) or the sign (if removing an item from inventory). This information is sent to the system. Step 6: The system receives the information and updates the database with either a +1 (if + sign was selected) or a - 1 (if minus sign was selected). Step 7: The system redisplays the updated inventory screen to the user with the new inventory quantity. ALTERNATE COURSES: Alt- Step 1: If the user has no items in the inventory database, notify the user that his or her inventory is empty. Alt- Step 5: If the inventory item is already at 0, the user cannot select the button. CONCLUSION: POST- CONDITION: The system sends the updated inventory screen to the user with the new inventory quantity. The newly updated Update Inventory screen is available for the user to input information about another inventory item. BUSINESS RULES Inventory are updated in increments of plus or minus 1 If the inventory is already at 0, the user cannot select the minus button CONTRAINTS AND SPECIFICATIONS ASSUMPTIONS: N/A N/A OPEN ISSUES: Need to determine how the user can add an item that is not in the inventory. CORRESPONDING FORMS AND REPORTS: Home screen and updated inventory screen. 12

16 Optional Materials Results of Research Interviews Interview 1: Sean Mulhern: Baton Rouge, Louisiana: Dominos Employee Having heard the description of this application, what are your first thoughts? I think it would be a very useful application for organizing and what not. I think this application would be great for new businesses in general. Being an employee at Dominos, do you think they would use this application or do they use something similar? At work we use a computer program that takes care of inventory. I think dominos would be interested in this application at least to see if it fits their needs. *Responses are paraphrased Interview 2: Avery Daman: Manhattan, New York: Actress Having heard the description of this application, what are your first thoughts? Yea it sounds like a pretty neat application and I like how it adds things to a grocery list. I m not entirely sure how much I would use it because I live in a small studio apartment and I really don t have space for a bunch of food so for the most part I already know what I have. Would this be an application you would refer to a friend or a small restaurant business? Are you asking me too? Yea I have a few friends that have gone to the store and came back only to realize they did not have any milk or sugar you know and have had a bad day because of it. I can definitely see how a restaurant could use this application because I can only imagine how much food goes in and out. So hypothetically speaking if you owned a restaurant would you use this application? Well that depends on what is out there. Apart from that can only imagine that I would use this application or another one like it. *Responses are paraphrased 16

20 Input By: Lauren Andrews Screen Shot Evaluation When first looking at the home screen of this app, it is very simple and straightforward. Ease of use is key to a lot of users. Although the colors are somewhat boring, it may not be a deciding factor in using the app. I like that the inventory screen is also simple. It would be useful to have a button at the top of the inventory screen that shows commonly used foods, recently used, or the user s favorites. You could have a star next to each item so the user could easily add it to their favorites. I like that the app will automatically send items to your shopping list when they are used from your inventory, but I would also add a (+) and (- ) options to add things that are not in the inventory or to delete items that the user does not want to buy again.
