The following specification particularly describes the invention and the manner in which it is performed.

FIELD OF THE INVENTION
The present invention in general relates to the field of telecommunication. More particularly the invention relates to customer experience measurement and management within the telecommunication industry.
BACKGROUND OF THE INVENTION
A major challenge with the current technology is that there is no unique way or process of capturing customer experience perception parameters and quantifying them against a standard scale across various mediums and interfaces prevalent in telecom service provider ecosystem. The current systems focus only on system level or operational level performance indicators to analyze the customer experience. At times, unstructured surveys are conducted to gauge customer satisfaction, which is primarily a limited scope and qualitative exercise. Further only a limited set of processes or system KPIs are identified that contribute to customer experience management. This leads to a false impression that the communication service providers (CSP) is performing customer experience management (CEM) tasks.
Customer experience between various interfaces and mediums in a telecom process are not captured in a methodical manner anywhere because of the lack of granularity, uniformity and also lack of mapping between CE factors (KPIs of customer experience) and processes & applications in the telecom operations. Moreover the state of art does not provide any solution that groups numerous customer experience perception parameters across various CSP-Customer interfaces / mediums in telecom service providers' ecosystem and quantifies all the perception parameter across a uniform scale to arrive at a logical decision point of identifying the precise parameters responsible for good or bad customer experience.
Customer perception parameters were traditionally calculated using electronic circuits as illustrated in prior art US6985559. However the system does the measurement of customer perception of one service (voice) only and captures quality in telephonic voice connection through small integrated circuit. Further there is no feedback or data collection from users/customer end. Therefore there exists a need of system which identifies perception

parameters across customer lifecycle (brand, marketing, product management, service procurement, service delivery, in-service activities) in telecom services providers segment and measures it on uniform scale to compute a total customer experience score.
US6985559 mentions a method of documenting the point of pain in current business operation for further improvement through preliminary survey of business capabilities. Point of pain here means errors or difficulties in current operation of business system. Thus a need is felt to collect information from plurality of data points and utilize the same for measurement of customer perception for telecom services.
One of the whitepapers of Siddhartha Shankar Ray titled 'Align Process Metrics to Measure Customer Experience in a Telecom Journey' elaborates on identifying the right measures and utilizing the Business Process Framework (eTOM) in the telecom journey. However a necessity of measuring customer experience parameter across plurality of mediums/interfaces is identified to be realized on a uniform scale to compute Total Customer experience Score.
In the light of the above mentioned challenges there exists a long-felt need to provide a comprehensive and detailed view of the identified critical processes and applications contributing to good or bad customer experience using RAG analysis within a telecom service lifecycle. The present invention proposes to address the need by mapping the customer experience parameters along with the scores & index to the eTOM processes and TAM standards.
OBJECTIVES OF THE INVENTION
The principle object of the present invention is to identify plurality of Telecom Processes and applications accountable for variation in customer experience (CE) score.
Another significant object of the invention is to map the customer experience perception parameters to telecom eTOM (processes) & TAM (applications) Standards.

It is another object of the present invention to Identify Telecom process/Application leading to Variation in CE score.
Yet another object of the invention is to classify and highlight telecom process/application in different categories of priority or management attention.
Another object of the invention is to comprehensively measure the customer experience against a host of interfaces and give out a Customer Experience Index (CEI) which indicates the customer's perception for a given CSP.
SUMMARY

The system then computes a total customer experience index depending upon weightage of individual customer experience parameters. The final step involves creating at least one pointer from each identified customer experience perception parameters to at least one recommended element for telecom process and application defined by eTOM processes & TAM standards to be further used for RAG analysis.

The present invention describes a system employing a customer experience measurement and management model that comprehensively measures and captures customer experience perception parameters against a host of CSP-Customer interfaces and from various perspectives, through a coordinated and participative process. Further it provides detailed insight into various Telecom process and application impacting the customer experience by using standard approach of eTOM processes & TAM applications for better understand ability.

A comprehensive approach to measure customer experience of a communication service provider is adopted by deploying a customizable, robust and flexible system. The system broadly comprises of a Customer Measurement Model and a Customer Management Model. While the Customer Measurement Model identifies all key parameters (experience parameter indicator, EP1) impacting a customer experience and measures the customer experience to derive a Customer Experience Index (CEI), the Customer Management Model identifies all key processes and application impacting the Customer Experience Measurement Score. . A holistic and standard approach for mapping all parameters to standard eTOM processes and TAM applications is adopted. Further Red-Amber-Green [RAG] analysis is performed for identification of critical processes and application using the score of Contact Point Interfaces (CPIs) from Customer experience measurement framework.
In one aspect, the customer experience measurement model of the system of the present invention performs the following steps. At first, identification of various customer experience perception parameters like Voice quality for VoIP calls, Perceived coverage, Successful Call Completion and the like is performed. Next, the identified perception parameters across various mediums & interfaces are quantified. This quantification is done through two ways depending upon the nature of Customer Experience Factors (CEFs). The CEFs which are directly related to customer's perception are collected through a pre-determined set of feedback mechanism and scaled on a uniform scale of-100 to +100. The CEFs which are relating to system parameters are once again mapped on the scale of -100 to +100 using CSP' strategy for the given experience area and targets of improvement. Further each area (Mediums/interfaces) has a different weightage vis a vis High, Medium, Low, and Not Applicable (H, M, L, NA) which can be varied as per the service provider's strategy and roadmap. Based on the different weight-age for different parameters, the aggregate Customer Experience Index (CEI) is computed.
In one other aspect the customer experience management model focuses on mapping the customer experience perception parameters to Telecom eTOM and TAM Standards. Based on the quantified customer experience parameters mapped to eTOM/TAM, the experience parameters are classified into three different categories. This classification into RED, AMBER & GREEN gives a logical identification of Telecom process/Application leading to variation in CE score.

The invention adopts a holistic approach of first grouping numerous customer experience perception parameters across various CSP-Customer Mediums / Interfaces in telecom service providers ecosystem and quantifying all the perception parameter across a uniform scale to arrive at logical decision points of identifying the contribution of CEFs to the good or bad customer experience of the customers. This measurement part is performed by the customer experience measurement model.
Next, the customer experience management model provides management intelligence by mapping the identified customer experience perception parameters to various applicable Telecom Systems and processes as defined by TM forum. This mapping along with scored experience parameters helps in classification of systems/processes in different categories of priority or management attention, i.e. RED, AMBER, GREEN.
Referring now to Figure 1, the components involved in the working of the Customer Experience Measurement & Management system 100 are broadly presented.
In one preferred embodiment the system 100 broadly consists of a CE Measurement Toolkit 102, CE Management Toolkit 104, identification module 106, Analyzer module 108, Classifier Module 110, Aggregator 112, Map Module 114, and a Reporting Module 116..
The CE Measurement Toolkit 102 is responsible for deriving Total CE index for CSPs based on their selected customer Interfaces & Mediums.
The CE Management Toolkit 104 is responsible for identifying Parameters & its mapped Applications & Process in Telecom Operations. Maps reporting Good or bad experience provide a basis for management action based on Priorities defined by RAG [ Red, Amber, Green ] Classification.
The CE Measurement Toolkit further comprises of:

The identification module 106 is responsible for identifying various experience areas, its related services mediums & interfaces which further comprises of various customer perception parameters relevant for Communication Service Providers (CSPs) ecosystem.
The Analyzer Module 108 is responsible for receiving customer feedback against identified customer experience parameters from plurality of data sources into experience factors database.
The Classifier Module 110 is responsible for collating the response available from various feedback sources to the respective experience areas, Services Medium, Interfaces and their related perception parameters.
The aggregator 112 Module is responsible for quantifying the perception parameters across a uniform scale of-100 to 100 and further compute Total Customer Experience Index based on weight-age assigned to various Experience areas, Mediums & Interfaces.
The Customer Management Toolkit further comprises of:
Map module 114 comprising a predefined set of recommended elements derived from industry standards for telecom processes & applications; and mapping them to each service medium & interface parameters to determine a degree of impact on said process & application.
The reporting module 116 is responsible for recommending the parameters & applications mapped to the derived customer experience score for mediums & interfaces as basis of segmentation and bringing details regarding extent to which parameters, applications & process are impacting customer experience to management notice for the purpose of change management and operational implementation.
Next, Figure 2 shows a step by step approach towards customer experience management planning and execution. In stage 1 customer experience programme objectives are defined. Stage 2 further involves four sub steps. While, stage 2a contributes to identification of the customer experience areas and their associated importance, stage 2b involves identification of channels/mediums in each area for which customer experience has been measured. Further stage

2c focuses on identifying experience factors in each channel/medium and lastly stage 2d links the associated factors, mediums and areas. Thus at the completion of stage 2 an architectural construct is obtained for Customer Experience Measurement Toolkit 102.
In the next stage 3 measurements of experience factors is performed for sample customers. Based on the results of stage 3 overall customer experience index is calculated in stage 4. Stage 5 involves identifying the good and bad experience areas based upon the customer experience index obtained in stage 4. Now post identification of good and bad experience (s) of the customer, mapping of these good and bad experience to standards of the telecom industry is performed by the customer experience management model 104 which is elaborated in stage 6. In stage 7 the customer experience index is assigned to the mapped process provides context or reasoning for the variation in CE score. Lastly in stage 8 customer experience improvement strategy is designed and is implemented to increase the overall customer experience in the complete lifecycle.
Referring now to Figure 3, the contact point mediums (CPMs) from where plurality of customer inputs is obtained from different data sources is illustrated. The figure shows categorization of said CPMs according to their level of importance. The levels of importance can be divided as H-high, M-Medium, L-Low and NA- Not applicable. The figure further details of the interface used at the CPM and to derive its relative importance. Based upon the derived importance the customer experience factor (CEF) is calculated. The next step involves categorizing the plurality of CEF's in H/M/L/NA based upon which the experience performance indicator (EPI) is calculated for the identified customer experience parameters.
Referring to figure 4, the invention can be broadly divided into CE Measurement (102) and CE Management (104) modules. The CE measurement module mainly includes the classifier 110 and the systematic analyzer 112 that work communicatively for quantitative analysis which subsequently leads to generation of EPI and CPI scores.
The aggregator 112, then, is used to generate a total customer experience index based on said scores. By using the EPI score as input the CE management module 104 identifies the eTOM

process and TAM applications that lead to undesirable customer experience in the whole cycle. The mapper module 114 of the system is used to assign pointers to the eTOM process and TAM application. In the final stage the reporting module 116 using a RAG analysis in combination with the predefined conditions classifies the eTOM processes and TAM application into Red, Amber and Green. The predefined conditions as shown in Table 1 are used for RAG analysis.
