UNIVERSITY OF TEXAS AT DALLAS SYSTEM ENGINEERING AND MANAGEMENT SYSM6309 – ADVANCED REQUIREMENTS ENGINEERING BILL OF MATERIALS GENERATION AUTOMATION FINAL TERM PAPER By: Adi Nugroho 8/3/2013 Submitted to: Dr. Lawrence Chung

Abstract 1. Introduction 1.1 Motivation Bill of materials is one document that plays The motivation of this paper is to create an important role in a project, especially in better understanding in redefining the telecommunications business. This requirement engineering for automation document reflects the expertise of a service tools that already build earlier during my provider company to select an appropriate project with one customer in solution in order to enhance and maintain telecommunication industry. Hopefully their network operation excellence. Any in the future requirement engineering errors that present in BOM generation knowledge that I have is able to make a process will not only produce delay on the significant contribution in new tools project is being executed but also indirectly development process that might be affect the performance of the network itself. made. Moreover BOM has important role on 1.2 Problem defining the customer’s project budget as well. Every single penny will be matters to As mentioned before, generating BOM the customers. That is mean; every single is a critical process in a project both for lack or excess material might make them our customer and customer. This work lose their business. However sometimes the can be categorized as time consuming BOM process itself often overlooked since job and need high accuracy when many people underestimate this document’s placing the proper materials with its creation, including sales and pricing quantity. Moreover the project manager. When they got some pressure from scalability itself will increase the risk so customer in the end they will force us, is the processing time hence can make us engineering team, to complete these loose the control when there is a lot of documents in a short period of time which is revision, like drop and insert, that being very risky to errors that may occur. In the made. Since this is the first time we other hand, we faced another problem in our create the automation, there are so many internal department like lack of resources requirements that might not defined due to company policy or high salaries of properly. Thus the purpose of this paper the contract engineers. This BOM is to review and redefine the generation automation is dedicated to automation’s requirements from basic facilitate the company’s internal process, like: provide better and excellent services to • Who is the stakeholder? customer and also in order to meet department’s efficiency targets announced • What are their requirements? by company’s top management team. • How can we fulfill the stakeholder’s requirements?

In order to have better idea about the • What is our limitation to fulfill process in creating a BOM, please refer those requirements? to Appendix A. The initial project • How can we check if a creation begin with pre-sale activities requirement is satisfied? where sales manager and solution manager work together to create the new business. After the customer gives good signal for the new contract then our 1.3 Solution team, engineering, start involve on the The requirements from the stakeholders to pre-sales by providing high level design. create BOM within limited time and in high accuracy makes us to come up with When the contract had been signed by automation solution using web based tools. customer, the next step is resources At this time we think that this is the based collection. Project manager has to find solution. However it might need some the technician and crew who will do the improvement in the future based on the installation on site. And for engineering, lesson learned so is the new requirement we have to find a designer based on the from the stakeholders. project scale. 1.4 Related Work After all resources are ready then we continue with the design process. In This BOM automation is not a new thing. parallel, project manager will conduct There are so many similar software and the site survey and give the report to tools like the one we build. Our tools engineering team as one of input for the basically only dedicated for specific project design. that we were working and might not applicable in other projects or other Output of the design will be design industries. document plus site survey result, and based on this document we have to 1.5 Outline generate the BOM in order to provide basic calculation on the pricing to the Section 2 of this paper talks in general about Bill sales team. Basic calculation means the of Materials Generation Automation equipment’s pricing only, before they requirements engineering. The focus of the add more services pricing, local challenges discussed here will be presented in materials quote, as well as margin for the section 3. Section 4 describes my investigation sales itself. All of these calculations will about the automation that we build and the be bundled as PO draft. Customer must finding as well. This research paper ends with review it first before issuing the PO to the conclusions in section 5. our company. 2. Bill of Materials Generation Then after we receive the PO, the Automation solution manager will order all

equipment and in parallel, the project Now we can continue with the manager must preparing the warehouse requirement for the BOM itself. For and all activities related to logistic more detail about the requirements handling, like how they will provide please refer to Appendix B which temporary storage for unimplemented contains both Functional Diagram and equipment and how they will deliver Non-Functional Diagram. those equipment to each sites. For the class diagram which explain how The rollout phase will start as soon as the system work is shown on Appendix the equipment is ready. Project manager C. So basically the automation was are responsible for this project replacing the manual work. The input execution, meanwhile sales and solution and output file beside it and the external manager will monitor the rollout process will be same as in the manual process. If they have question about the work. The automation system part of the project’s time frame or budget, they can diagram shows how we can fulfill the ask the project manager to provide it stakeholder requirements. anytime during the rollout phase. The engineering provide integration support services for the field team if they meet 3. Challenge problem that they cannot solve by them The challenges and limitations that we self. have to fulfill those requirements are as Every time the implementation and mentioned by list below: integration have been done for one site, - The database engine and software the acceptance test will be conducted that we used to build the automation and both parties must attend it. After the tools are still using trial version test has been done the work well as which did not give us a lot of options expected then customer will sign the to do more. document. At this point we can say that the project has been executed for that - The human resources who involve site. The same process will be executed the automation development are still for all sites until the last one and the in learning curve. Programmer still project will be closed. Even the project learning how to understand the was closed; the sales manager still has telecom technology and in the other responsibility to give project review hand the telecom engineers are not report. 100% aware about the limitation that the programmer have. It will take The high level process is already time for both to build this cross explained and we can conclude that the competence. stakeholder will be the customer, sales manager, solution manager, and project manager.
