BPM Expert / Business Transformation Subject Matter Expert, Inteectus Consuting Services Casabanca, Morocco 3 Senior Manager MTN Business Service Deivery / Project Manager Abidjan, Ivory Coast 4 MSC., Business Saes and Reporting Expert MTN Business / Project Coordinator Abidjan, Ivory Coast Abstract The business transformation, a wordwide trend in many industries, is to improve the business performance in order to remain competitive in a chaenging market. To accompany Teco industry in this trend, TM Forum issued Frameworx which addresses the key business aspects namey process, information, appication and integration ones. The purpose of this paper is to present a methodoogy for Teco business process transformation harmonizing Frameworx and Lean Six Sigma (L6S) since it is we proven methodoogy supporting this transformation. This harmonization increases the L6S agiity. The focus of the current paper is on the Define phase of L6S, with some highights about other phases, supported by a case study. The Define phase activities a together are named Core Engineering aspects.

The Business Transformation, De Facto soution for the chaenges of the TELCO industry In the dynamic of the TELCO industry, there are mutipe types of actors incuding, to name some of them, content providers, terminas and equipment vendors,, integrators, socia networks providers, service providers, TELCO products distributors and any TELCO provider or consumer. These types a together make the TELCO vaue chain. This industry is today under the pressure of a changing and chaenging business context (Ex.: Customer Experience chaenges and socia media, quick changes with mergers and acquisitions, new unexpected entrants, new technoogies, margins compression, operationa efficiency, cost optimization) which threatens the competitiveness and even the surviva of an actor. Given such dynamics, TELCO industry payers are more and more adopting the soution «Business Transformation» to overcome the chaenges of such a business context. This increasing adoption is justified by is justified by its practica reevance and the very positive feedback from the market with severa rea case studies. Indeed, companies who adopted and impemented this soution have seen a return (ROI) and vaue (VOI) on Investment. In a subsequent section, a "Success Story" wi be presented with the obtained ROI and VOI. The key
2 IJCSI Internationa Journa of Computer Science Issues, Vo. 10, Issue 1, No 1, January eements subject to transformation, as presented in the Figure1, are the Business Mode and Product Portfoio, Customer Experience, Business & Staff Cuture, Business Processes, IT & systems and infrastructure. Figure2: Frameworx and its key components Figure1: Key eements subject to Business Transformation 2. How to Transformation? acceerate Business In a word characterized by responsiveness and speed, it is very natura to ask how to acceerate Business Transformation? The TELCO industry adopts massivey TM Forum Frameworx as an acceerator for this transformation. Today 8 of the Top 10 wordwide service providers use and adopt Frameworx. This adoption is justified, as previousy expained, by the ROI and VOI obtained with the sogan «Do not start your transformation initiatives from scratch, use tmforum Frameworx as an efficient and reiabe acceerator». TM Forum Frameworx, as shown in the Figure2, and its components (caed Frameworks) answer four key concerns reated to the business transformation. First, The Business Process Framework (etom) answers the concern «How to improve / structure / define the business processes supporting the Business?». Secondy, the Information Framework (SID) answers the concern «How to improve / structure / define the information manipuated by the business processes?». Then, the Integration Framework (TNA) answers the concern «How to improve / structure / define the interaction between my business processes & the manipuated information and how to support the appication deveopment?». Finay, the Appication Framework (TAM) answers the concern «How to improve / structure / define the appications supporting my business processes?». And to measure the business performance, TM Forum issued the Business Metrics Framework. This framework is composed of three major performance domains with their reated metrics. These three, the piars of the baanced scorecard, are: The Customer Experience o Metric exampe: % Orders Deivered By Committed Date (ID:F-CE-2c ) The Operationa Efficiency and o Metric exampe: Fufiment Process Cost As % OpEx (ID: F-OE-1c) Revenue & Margin. o Metric exampe: OpEx / CapEx (ID: GRM-2) 3. How to start Business Transformation for inefficient operations? The startup of the Business Transformation for inefficient operations, as mentioned in Figure1, is based on two goden rues. The first rue is that «automation appied to an efficient operations wi magnify the efficiency» Bi Gates. The second rue is that «automation appied to an inefficient operations wi magnify the inefficiency» Bi Gates. Based on these goden rues, the starting point to transform inefficient operations is the Business Process Reengineering (BPR) with the Sogan «Improvement before automation». BPR is being widey used jointy with Lean Six Sigma Methodoogy for better process optimization. 4. The BPR and process decomposition In the engineering word, the architecture deveopment of the work to be done is crucia and fundamenta «I Pan my work first» and represents a fundamenta principe. The BPR, part of this word, foows by syogism this principe. Therefore, the business process architecture shoud be deveoped. This architecture breaks down and decomposes activities into severa eves (0, 1, 2, etc).
3 IJCSI Internationa Journa of Computer Science Issues, Vo. 10, Issue 1, No 1, January In order to support the deveopment of such a process architecture and decomposition, many key actors in the TELCO industry have chosen etom. 5. About etom etom provides a standard process architecture, terminoogy, cassification scheme and decomposition hierarchy. etom covers a business activities, with more detaied aspects than others, to meet the needs and interests of the TELCO industry with its major trends. The etom suggested process architecture, as shown in Figure3, is composed of three Process areas. First, The Strategy, Infrastructure & Product Process Area incudes processes that deveop strategy, commit to the enterprise, buid infrastructure, deveop and manage products, and that deveop and manage the Suppy Chain. In the etom, infrastructure refers to more than just the IT and resource infrastructure that supports products and services. It incudes the infrastructure required to support functiona processes, e.g., Customer Reationship (CRM). These processes direct and enabe the Operations processes. The three process areas are further decomposed into further eves of decomposition which coud be customized. Thus, etom is an open Framework aowing the specific needs of a given company to be integrated in it. 6. The BPR and process fows The BPR starts by deveoping a process architecture and decomposition as previousy expained. This architecture/decomposition is made of process eements which form a ibrary. Initia process fows coud be constructed by seecting the appropriate process eements from the ibrary based on the business context to mode. For detaied process fows, a detaied descriptive sheet wi be eaborated for each process eement. This sheet is simpy named a Use Case. The key eements of a use case are the Name, Goa, Description, Actors, Pre-conditions, Triggers, Essentia steps, Manipuated information, Postconditions and Business rues. A the use cases, within the scope of work, wi form the Use Cases repository. To buid a process fow, a set of use cases suitabe to the business context to mode wi be seected from the use cases repository. Then the process fow wi be an orchestration, via a sequence, of the reated use cases. 7. Lean Six Sigma (L6S) in a nutshe Introduction Figure3: The Business Process Framework (etom) Then, the Operations (OPS) process area contains the direct operations vertica end-end process groupings of Fufiment, Assurance & Biing (the FAB process groupings), together with the Operations Support & process grouping. The FAB process groupings are sometimes referred to as Customer Operations processes. Then, the Enterprise Process Area incudes basic business processes required to run any business. These processes focus on Enterprise Leve processes, goas and objectives. These processes have interfaces with amost every other process in the enterprise, whether operationa, product or infrastructure processes. These are sometimes considered corporate functions and/or processes, e.g., Financia, Human Resources processes, etc. Lean Six Sigma is a step by step methodoogy to optimize the process performance. The methodoogy steps, known as DMAIC, are: Define: the main purpose is to define the project, the team and the process Measure: the main purpose is to vaidate the measurement system and coect process data Anayze: the main purpose is to anayze the process data in order to identify the root causes for the probems and non performance Innovate: the main purpose is to find, assess and aunch the process improvements ideas Contro: the main purpose is to ensure a sustainabe process improvement 7.2 Define Phase: Activities and Deiverabes The key activities reated to the Define Phase are: Set project goa (s) Define the project objectives Define the project scope 1

Concusion This paper suggests a methodoogy harmonizing Lean Six Sigma and Frameworx seected components with a focus on the engineering aspects reated to the process. This harmonization, caed L6S-Teco, aows quicker Transformation projects and getting standardization benefits since Frameworx components are used throughout the methodoogy where appicabe as inputs for the design aspects. It does generate Six Sigma benefits as shown in the case study s methodoogy benefits. L6S-Teco is an approach to address business process transformation for Teco industry and might be appicabe to many other service companies since many of the Frameworx components and Lean Six Sigma are too. The harmonization wi optimize the CaPex and eventuay OpEx since one singe optimized project is executed to address two major needs namey process design and performance. The current paper coud be as input for the coming artice (s) to appy L6S-Teco to other end to end business streams reated to the customer, Network and Product. It can be aso a basis to consider other ayers of the enterprise architecture (Information, Appication, Technoogy) to have an end to end business transformation.
