Acme Electric LLC 5/3/2020 The company Acme Electric, LLC (Acme) is a local electrical company that does all phases of electrical work including residential, commercial, outdoors, new and remodel as well as service work. They service Duval, Clay, St. Johns, Nassau and Baker counties, in Florida and are available six days a week from 8:00 am to 6:00 pm, and Sundays by appointment. They are always available for free estimates and emergency calls. The people Tom is the owner and has three crews of two people each. Each crew is assigned their own van. On each crew, one person is designated as the crew team leader/electrician and the other an electrician. Tom himself sometimes acts as a crew of one electrician using his truck. There is one supply/maintenance person (Supply) who is responsible for ordering and maintaining electrical supplies as well as maintaining the companys vehicles. The Jobs The company has several categories of Jobs commercial vs. residential and planned vs. ad hoc. Normally all the commercial Jobs are planned, while the residential Jobs are a mix of planned and ad hoc. The customers are categorized as new or existing. The work day Supply maintains a stock of electrical parts and supplies so that the crews can stock their van at the beginning of the work day with what they are told they will need for the days scheduled work or they anticipate they will need. If stock is not available, Supply may direct the crew to drive to a 3rd party electrical supply store on their way to the first Job or between Jobs. There, they obtain the anticipated, necessary stock for the scheduled work. During the work day, if the crew determines they need stock not on the van, they will either obtain it from the companys stock area, any 3rd party electrical supply store close to the Job site, or call Supply requesting the item(s). The 3rd party electrical supply store, Supply, or Tom may deliver the additional supplies directly to the Job site. At the end of the work day, the crew leaders provide Supply with receipts of stock obtained from 3rd party electrical supply store(s). They also provide Tom with a list of the material used that were not on the Bill of Materials (BOM), items that were on the BOM but not used, and their crews labor hours separated by Job. Supply knows what and how many items to keep in his stock. Each week Supply physically inventories the stock, creates a list of items to purchase, and purchases the items on the list. Printed on 5/3/20 Page 2 of 6 pages Each crews van has a stock of commonly used items as well. At the conclusion of the work day, each crew restocks their van from Supplys stock room and notifies Supply of any items they are unable to restock. Each electrician provides their own personal tools for use on a job. These are items like screwdrivers, hammers, tool belt, etc. - Acme provides no personal tools. Tom maintains contact throughout the day with crews team leader via a smartphone. They use text as well as voice to communicate. The team leader uses a map application on the smartphone for mapping to locate Job sites. The company contracts with a 3rd party vehicle maintenance company to maintain their fleet of vehicles. Currently the company has three Ford E250 vans and one Ford F250 truck. At the end of each workday, each assigned driver reports the vehicles mileage to Supply. Assigned drivers report immediately to Supply when they detect any possible vehicle issues that might require immediate or emergency repairs. Supply calls the 3rd party vehicle maintenance company to schedule both normal maintenance or immediate/emergency repairs. When vehicle drivers fuel the vehicles, they note the vehicle mileage, date, and time on the receipt. They then pass on those fuel receipts to Supply at the end of the day. At the same time, they also provide Supply with any other vehicle-related receipts acquired during the day. Each work day morning the crews arrive at Toms shop to prepare for the day. Tom gives each crew: 1. A list of Jobs by crew that the crew is to work on that day, and the order that Tom wants them completed. 2. A list of material for each Job, aka a Bill of Materials (BOM). The crew then either pulls the BOM from the stock room or Tom tells them what, when, and where to pick up the BOM or partial BOM from a 3rd party electrical supply store. A 3rd party electrical supply store may deliver additional BOM directly to the Job site. 3. Any special instructions about each Job. 4. Any special instructions about their days itinerary. At the end of the work day, the crews return to Toms shop. They: 1. Report verbally to Tom about their work day. 2. Provide receipts to Supply for any items purchased, including but not limited to, fuel, oil, materials, supplies, special equipment, etc. 3. The crew leader reports the vans ending mileage to Supply. Definition of a Job Tom may receive a verbal or written Request for Proposal (RFP) from an existing or potential Customer. An RFP is a document written and sent by an existing or potential customer detailing the requested service. Generically, it is a method through which a business sends requests to a number of contractors so that these potential contractors can create and send proposals back to the Customer in response to the RFP. When Tom receives Printed on 5/3/20 Page 3 of 6 pages an RFP, he prepares and sends a Proposal back to the requesting Customer. Toms proposals are in the form of a Job with a status of proposed. The Customer can accept one of contractors proposals. If the Customer accepts Acmes proposal, the Customer signs and returns the proposal to Acme. Upon receipt of the signed proposal, Tom changes the Jobs status from proposed to accepted. Each Job exists in exactly one status at any point in time. It may start out as a Proposed Job, then move to Accepted, Scheduled, In-process, Completed, Invoiced, and Paid in that order. 1.

Printed on 5/3/20 Page 4 of 6 pages Figure 1: Job Status State Diagram The proposed systems Tom wants an information system to assist with running the company and to keep information updated in real-time. He envisions possibly an office computer as the central repository for all information with his team leaders having mobile devices connecting in realtime to update field data as work is completed throughout the day. A Job Management System: 1. Tom wants to: Record a Windows Uniform Resource Identifier (URI) for local files related to a Job and stored on the computer. Each URI will be a link to a local file.
