Executive Summary

ShoppingCart, an iOS application, to be developed by SOCO Developers would be used as a budgeting aide while grocery shopping. The app works as a virtual shopping cart. When an item is chosen one would scan the bar code of said item and the item would be added to the app’s shopping cart along with its cost at that store. ShoppingCart would keep a running total of the items in your cart and automatically add the tax to the total. This app will make it much easier to stick to your budget for food eliminating all excuses for frivolous overspending. Access to the stores’ price database is provided by selecting a store in the ShoppingCart application.

Target audience will be individuals who are shopping on a budget. Anyone can benefit from this app, but the ones who will experience the most benefits would be those who have a strict budget to which they must adhere. In today’s economy, many individuals are living on a budget and SOCO Developers believes that this app will help individuals manage their expenses at the grocery store and ultimately cut down on spending. Since this is an iOS operating system, individuals who have an apple product such as the iPhone or iPad, will be the only ones who could benefit from this app. However, SOCO Developers felt that there is a large population of individuals who are using an iPhone or iPad therefore a large volume of individuals would have access to Shopping Cart.

SOCO Developers’ vision for this app is to help young adults just getting out into the world and trying to manage their grocery expenses or families that need to stay within a budget. It’s very easy to walk into a grocery store and pick anything off of the shelf that you want, but once individuals check out they realize how much money was wasted on items that they didn’t even need. Shopping Cart will allow it’s users to create a grocery list of items needed as well as a targeted budget, eliminating overspending on unnecessary items.

The App will consist of several screens. The first screen will be the home screen with tabs to take the user to other screens. These will be the Shopping List, Shopping Cart, Budget, and Store Selection. Each tab will bring you to that page. The Shopping List page will be just a basic list with customizable categories to organize your groceries. The Shopping Cart page will be the virtual cart to be used while shopping. That page will contain a list that can be deleted by a single finger swipe over the item to delete as well as a scan button to add new items. The total amount of groceries in your shopping cart will be displayed at the lower bottom right of the screen. When the amount of the items becomes greater than the amount selected as the budget the numbers will turn red indicating an overage. The Budget page will be where one could set their budget either weekly, bi-weekly, or monthly. Lastly the Store selection page will list the stores that you have visited in the past that are available with our system. These pages will work together to put some very use full tools in the users hand.

Scope StatementShoppingCart Prepared by: SOCO DevelopersStatement of Project Scope Date: 22 September 2012

General Project Information Project Name: ShoppingCart Project Contact: Brittany Gauthier Project Employer: SOCO Developers

Problem/Opportunity Statement:Many people want to keep a running total of the items they are buying while

shopping. It is inconvenient to “price check” multiple items, add totals together, and try to figure out tax. An improvement needs to be made to make shopping on a budget easier for customers.

Project Objectives:ShoppingCart is designed to enable shoppers to make a virtual shopping list. Once

these items are scanned, the price database will retrieve prices, strikethrough the specific item on the list, and keep a running total.

Project Description:An iOS app will be developed that will allow customers to create their shopping list

and keep a running total of the prices as they shop.

Business Benefits: Enhanced perception of purchaser buying patterns Improved budget planning and management Enhances competitive edge throughout business who will use ShoppingCart

Project Deliverables: User log-in Convenient data entry for customers SOCO Developers-only access to data modification and individual stores’ databases Database to store customer information and preferences

Estimated Project Duration:5 months

System DescriptionTarget Audience

As the name suggests, ShoppingCart is designed for shoppers with monetary constraints. Target audience will be individuals who are shopping on a budget. Anyone can benefit from this app, but the ones who will experience the most benefits would be those who have a strict budget to which they must adhere. There are some applications that offer the same things we do such as GroceryPal, Shopping List, Grocery IQ, and Grocery gadget, but there are no applications that can bundle all of these features together.

Identification and Analysis of Stakeholders

The skillset needed to access all of the capabilities of this app they need only have basic knowledge of navigation of the iOS device. The app is very user-friendly. The people who are going to shop will appeal to ShoppingCart. The Apple iPhone has roughly 30.1 million users. Every one of these phones is our target audience. However, it is not feasible that all iPhone users will download the ShoppingCart app. We have estimated that the satisfactory download rate of 50% of the iPhone users. The system will support barcode and QR scans, multiple item entry into virtual shopping cart, simple addition functions, tax calculator, discount calculator, list builder, and provide feedback on the performance of the system. The users are going to expect an easy-to-use system that will help them rather than hinder them in their everyday shopping experiences. This will inspire us to make the most basic design we can to perform a complex procedure in a matter of seconds.

Model of Current System

The current system as we see it now consists of paper shopping lists, lists in the iPhone app Notes, and calculators to achieve these same results in a much more lengthy time. Competing products include shopping list apps, but they fall short when it comes to including prices, tax, and in-store assistance for shopping.

Results of Research SOCO Developers conducted a survey on ISDS 3100 students asking a few of them

questions. The purpose of the survey was to study is our idea needed in market and whether it looks like a successful business idea or not. The survey comprised of 4 questions that could help us realize other’s opinions about our idea. We generated an online survey using Google Docs as it is a very simple solution to build online forms.

Interview question 1

The first question asked in the survey was: How do you create your grocery list? We asked questions to get an idea of how people create their grocery list and understand how much our app will benefit them by making their job easier. The responses of people included: “Brainpower”, “using the iPhone App Notes”, “Rummage through my fridge and pantry and write what I need as I go.”, “on a piece of notebook paper”. All the other responses were pretty much on the same grounds as the ones states above.


The second question asked in the survey was: Do you have an iPhone? The purpose of this question was to prove that majority of the people use iOS and hence making an app for iOS will ensure we have a market for our app. The results of the app show us that 24 out of 26 people who answered the survey have iPhone.

Do you have an iPhone?Yes 24 92%

No 2 8%


The third question was: Do you shop on a budget? The question received 22 responses as a “yes”. This clearly shows that more than 80% people shop on a budget. Since our target users are those iOS users who shop on budget, we have very good chances making our app a success. The results of the question from the survey are

Do you shop on a budget?


The fourth and the last question of the survey was: If yes (question 3), would an app that tracks your total and adds tax to your shopping list as you shop interest you? This is what makes us believe that we are headed in the right direction. We can say that because 88% of the people said that they would like to have the kind of app that we are working on. Here is a graphical representation of the responses we got:

If yes, would an app that tracks your total and adds tax to your shopping list as you shop interest you?

Yes

88%

No 3 12%

Observation

As mentioned earlier the observation from the survey is easily understood and concludes that we are headed in the right direction. The people who use iOS and shop on a budget would get an app that would track their total with tax as they shop.
