It is a sole proprietorship firm as following details:<br />Name of the ProprietorLeAnn WalbeckAddress416 Water St Eau Claire, WI 54701Phone(715) 514-0226 <br />Organization Chart<br />Factors to Address Problem<br />After discussion with the proprietor and investigation of the systems, the team identified three primary concerns:<br />
    • Slow check-out: since the billing system is on a simple calculator, there is an impending need to upgrade the billing and check-out system to bring efficiencies and cut-down time consumed.
    • 2. Manual Inventory record-keeping: therefore more time consuming and often redundant. The store keeps a track of inventory by physically viewing the level of stock remaining for all items.
    • 3. High cost of maintaining inventory records: since the records are maintained manually, the cost of maintaining inventory stocks is high because of man-hours consumed.
    • 4. Recognition of the problem areas led us to identify the course of action and possible solution as elaborated in the following sections.
    Project Objective<br />Device a more efficient inventory system<br />The team realized that there a scope of improvement in the inventory system which can bring time efficiencies, cost effectiveness and reduce chances of redundancy and errors in data recording and updation, by better use of technology. <br />Feasibility Analysis<br />Economic feasibility<br />After thorough analysis, the team recognized that implementation of an inventory system would yield following tangible benefits to the store:<br />
    • Cost reduction or avoidance
    • 5. Error reduction
    • 6. Increased flexibility
    • 7. Increased speed of activity
    • 8. Improvement in management
    • 9. Miscellaneous
    Below is a chart of our calculated tangible benefits. The new inventory system would increase the speed of sales because it is all computerized therefore being able to handle more customers on a timely fashion.<br />

    Intangible benefits would include the following:<br />
    • More Timely information from quick inventory reports from the inventory software.
    • 10. Less stress on the owner
    • 11. Competitive improvement
    Cost of new system: <br />Onetime costs: Below is a chart of our one-time cost analyst. The new hardware/software will be state of the art technology so it will be the most expensive. The development costs consist of paying the developers to design the system. For new hardware and software, these costs consist buying the computer, the laser scanner, and the custom software that we developed. User training is the cost for their employees to receive effective training on the system. The site preparation costs are the costs of setting up networking for the system to communicate with the suppliers. <br />

    Recurring costs: Below is our recurring cost analyst chart. We figured that the supplies would cost much less than before because you won’t need as much paper. For the Incremental data storage, the more products the company has in the system, the more memory that the system will need. For the incremental communicators, the cost of having a phone line and internet capabilities is a recurring cost for this company. <br />

    Break even analysis<br />After we figured out our tangible benefits, one-time cost, and recurring costs we were able to figure out our NPV. Our NPV came out to be $16,898 with an ROI of 42%.<br />According the break even analysis above we will be making profit by the beginning of the 3rd year and will continue grow.<br />Technical & Operational Feasibility<br />The biggest technical challenge would be to have the weighing system accurately weigh the products so that the inventory system works as accurately as possible. Once in place, the training of the employees takes a few days for them to be totally comfortable. Maintenance will be needed on the Inventory system for the addition of new products and to check if the scale is working properly on a normal basis. This maintenance will be done by our organization as part of the deal to produce the system. We will come in to maintain and test the system bi-monthly for any flaws. The technology we implemented is very reliable to ensure smooth transactions but will require updates when new products are introduced.<br /> Legal & Political Feasibility<br />Since this is a private company there’s very few people involved. The biggest stakeholder would be the owner and the supplier of products. If business declines the owner may be driven out of business but probably won’t affect the supplier much because it’s a larger and more established company.<br />Information Requirements<br />To plan, analyze, design and implement the new system, we would need the following categories of information:<br />System Overview<br />Brief System Description<br />The new system will have entire inventory management automated. This involves having a universal bar code for every product in the store. When a sales occurs, the sales person will scan the bar code on the product. The computer will recognize the item being sold, quantity sold (weight or numbers), price, etc. Once the quantity of all the products sold is known, the system will know exactly how much less inventory available, and will remove the same quantity from stock available. <br />The system will also have a pre-identified level of inventory replenishment level. Whenever a stock of any commodity goes below minimum level, the system will identify it and inform the Manager. Manager, depending upon need and his judgment, will re-order. <br />Use Case<br />Context DFD<br />Hardware<br />
    • Computer
    • 24. Printer
    • 25. Laser Scanner
    • 26. A new weighing machine which is computer-compatible (if required)
    Project Schedule<br />Our project is broken down into 8 steps and it will take about 14 weeks to complete. The project is broken down like this because it’s the most effective way of completing. The structure of this schedule allows developers enough time to fully develop the system to its wanted potential. The most complex part of the project will be the programming and user documentation. This is because of how we want our inventory system to run. <br />Design Specification<br />Logical Design<br />Use Case<br />DFD’s<br />ERD’s<br />Input, Output Interface Design<br />Forms – Chocolates & Sweet Things counter sales form<br /> Reports – Chocolates & Sweet Things <br />

    Test Plan<br />Manual testing: steps involved:<br />Implementation Plan<br />Installation<br />Direct implementation plan: since the existing system is manual and an automated inventory system does not exist, there is a need to implement a new system from scratch. We plan to implement the new system and stop using the paper system with immediate effect. <br />User training<br />Since the client is a small company, employees only 3 people, and the systems suggested are fairly simple, the training needs are also fairly simple and are as follows:<br />
    • Training program on how to use computers (if needed0
    • 33. Training program on operating Microsoft Office, emphasis on MS Excel (if needed)
    • 34. Training program on using Laser Scanner- refer to user manual
    Post-Installation Review<br />We will check up on the installed system once a week for the first month to see if there are any problems.<br />Reflection on System Development Process<br />This was very good hands on learning experience that will be beneficial to us and to are our future careers. We learned about the hardships endured as well when working on a project of this magnitude. A project like this requires a team that is willing to make sacrifices in order to get things done. We had some difficulties putting the system together because we were still learning about all the processes that went into it. We had to do a lot of self research so we could understand what kind of system we were producing. <br />If we could do it all over again we would assess the entire outlook of the system differently because we would have more knowledge about the SDLC which would help get the project quicker. <br />Appendix<br />Record of Team Meetings<br />VenueAgendaTime and datedurationUWEC- SchneiderDecision on project topicSeptember 22 20071 hrChocolate and Sweet ThingsOverlook of the existing systemSeptember 28, 200730 minsUWEC- McIntyre LibraryDecision on project proposalOctober 1, 20073 hrsUWEC- McIntyre LibraryCreating the project reportNovember 8, 20071 hrUWEC- McIntyre LibraryCreating the project reportNovember 14, 20073 hrsUWEC- McIntyre LibraryCreating the project reportDecember 7, 20072 hrsUWEC- McIntyre LibraryPrepare presentationDecember 8, 20071 hr<br />Communications between Team Members<br />ModeFrequencyTotal number of timesD2L- discussion boardTwice a week19EmailsEvery day20Phone Twice a week10MeetingsWeekly12Visit at the store5<br />Records of Interview with Chocolates & Sweet Things<br />We Interviewed the owner on the following dates: September 15, 2007, October 10, 2007.
