Mission Statement, technology environment, computer systems, marketing plans, rapidly changing market trends and technologies, challenges of the market, implement new software, introduce new services, software development and techniques, manage those risks Application Testing, Requirement Review hidden, redundant and/or excessive requirements we analyze your existing requirement documents Four levels are identified and examined: Business Requirements, User Requirements, Functional Requirements and Non-Functional Requirements. We make your requirements traceable for Specification Analysis, Acceptance and Change Request Assessment. Specification Analysis We ensure that your requirements are adhered to by reviewing the specifications before approval, so differing expectations and resulting disagreements can be prevented from the very beginning. Additionally specifications have to reflect implicit requirements - like compliance with national and international regulations and recommendations - that may have been unspoken but are nevertheless mandatory. Use Case Extraction & Test Case Creation Use Case Extraction is a modeling technique used to describe requirements from the user's point of view in a categorized, systematized and retraceable way. Use Cases make requirements testable. Subsequently Test Cases are created by combining Use Cases with Test Data. A Test Case explains exactly what values or conditions will be sent to the software and what result is expected. Test Planning Our Test-Engineers develop custom-tailored test-plans that encompass human- and time resources as well as test calendars. In addition the test plans contain the general test strategy and the prioritization of test activities (risk first). Generation of Test Data Test Data is essential for executing Test Cases. Our Test Data is built in a way that the testing effort can be minimized. The advantages of generating test data are: approved & standardized input, independence of real data, time & resource savings, reusability, large amount of test calls, intentionally erroneous calls Test Execution We use dedicated test environments for each test area synchronized by master test plans and scheduled by test calendars. The goal is to simulate the reality during a defined time-period. Even under extreme time pressure our experts are able to accomplish your objectives. Documentation & Reporting As a matter of principle we keep detailed and systematic reports and documentation on the test services provided. Requirements Management Requirement Analysis In the beginning it is of utmost importance to define needs, goals and objectives, identify stakeholders and interfaces and realize the visions and expectations of the customer. Only then we collect the requirements of all stakeholders and assemble them. To accomplish this target we provide experts who fully understand your functional requirements as well as the importance of non-functional and supplementary requirements. Use Case approach From our experience we learnt that the Use Case method is the most effective way to achieve best practice in managing requirements. Use Cases help to manage complexity, provide a basic groundwork for requirement- and specification documents, user and training manuals and Test Cases. End-to-end Traceability To avoid that your Requirements get lost on the way while your project proceeds from the initial Requirement creation to the Technical Specification and on to the Test Phase, you have to make them retraceable. Using Requirement Management tools enables us to integrate Requirement Management-, Error Tracking- and Test Management processes to detect the loss. A Requirements Traceability Matrix will point out where Requirements are missing and/or specification documents are incomplete. In addition traceable Requirements are a powerful instrument to distinguish between valid and questionable Change Requests.. Test Management Test Suite Implementations We support the management of Test Suites from all prevalent vendors for Load Tests, Performance Tests, GUI and API Tests, Application & Web Tests. Our consultants work with you to create a tailored implementation plan covering initial project assessment, rollout, mentoring, training and administration. Change & Release Management Change Management Tools are vital for tracking the versions and the reasons behind the changes. Integrating software changes into our test strategy at an early stage of a project leads to improved flexibility, reliability and speed. Version Control and central storage of software ensure that correct versions of the software are tested and rolled out. Design of Acceptance Criteria Our experts will create Acceptance Criteria and Guidelines to ensure that the delivered products correspond exactly with your requirements. Management of Test Environments The careful planning of Test Environment architecture is crucial for running tests efficiently. Our Test Engineers have long experience in designing and maintaining dedicated test environments for each test area, working with a master test plan - synchronizing end-to-end tests using multiple environments simultaneously, scheduling tests in test calendars - for coordinating time dependent test-cases while aging a test-environment and exchanging data between test environments - for subsequent test activities in other environments avoiding redundancy and saving time. Error Tracking We provide the evaluation, installation & configuration and training of automated defect tracking tools including the design of role-models, state diagrams and error classes. Defect tracking is extremely useful for risk assessment. Used as a knowledge database the collected information facilitates help-desk support after roll-out. Training & Coaching To support you in introducing professional test processes to your company we provide goal-oriented training on test methodology and test tools. After finishing the training your staff will be capable of mastering the daily test challenges. For individual problems high-level coaching is provided on demand. Test Data Generation Generated Test Data has a couple of benefits you cannot neglect. It is "virtual" so you have no legal obstacles in using it It can be generated on demand. No tedious extraction from your production system is necessary It can be intentionally erroneous so negative test cases can easily be tested Our tools are so flexible that other formats & protocols can be easily generated after a preparation phase of a couple of days.

Based on the collected information we set up an ongoing coaching of an integrated quality management system (e.g. based on ISO 9001:2000, ISO 14000, etc.). Process Management Process Design In the phase of process design we setup key performance indicators (KPI's) to measure and control the processes. The KPI's are often used as input to a Balanced Score Card for the Top-Management. Additionally we offer enterprise specific trainings for process management. Process Analysis We analyze your legacy business processes, perform process consolidation and design target business processes based on new requirements. Process Compliance We check the compliance of your business processes to common and applicable standards or business process frameworks like eTOM. Revenue Assurance Methodology Our Revenue Assurance methodology focuses on the key areas of your business, where our systems integration skills and in-depth knowledge of communications business processes can recapture the richest pools of revenue losses. Our end-to-end view of business architecture covers both - business support systems and operational billing systems. Switch to Bill Audit Our tests encompass all services and challenge the system's ability to rate effectively by targeting all possible rate plans. This might include hitting peak and off-peak hours, as well as positive and negative testing to determine which calls should or should not pass through the system. Our experts monitor systems for possible revenue leakage, focusing on four main areas: switch integrity, message processing, roamer verification and bill audits. CDR Verification Regardless of the tool used during switch verification, the general premise is the same. Test calls are typically used to check the switch's performance. While many providers still may determine their test call patterns manually, some tools do this automatically. Others may decide to simulate calls to avoid the expense of actually running test calls. Cellconsult is supporting both alternatives. Revenue Stream Integrity We deploy a testing system with our experts and run continuous end-to-end testing, providing you with the results you need to validate the integrity of your revenue stream. This allows you to quickly recover lost revenue, create a self-funding program, benchmark these results against the results of the industry, and improve the quality of your customer bills. Fraud Detection Enhancement We have the expertise to generate fraudulent call data rarely occurring in the network. This particular knowledge enables us to check fraud systems exhaustively and to find even the proverbial needle in the haystack. To avoid hidden, redundant and/or excessive requirements we analyze your existing requirement documents. Four levels are identified and examined: Business Requirements, User Requirements, Functional Requirements and Non-Functional Requirements. We make your requirements traceable for Specification Analysis, Acceptance and Change Request Assessment For the Euro conversion of SiMobil's billing system Cellconsult developed a Basic Euro Concept and Impact Assessment including the collection and definition of all requirements. The creation of flow-cases for external interfaces and the development of financial test cases guaranteed the seamless crossover from the Slovenian Tolar the the Euro Cellconsult planned and executed acceptance tests for the implementation of Telekom Austria's new billing system. Our objective was to accompany requirement and specification phases, carry out the user acceptance tests and help the customer to replace IP, IN and wireline systems to provide a convergent bill for his subscribers Managing Director of Cellconsult was interviewed by Austria's business magazine Wirtschaftsblatt. "...Cellconsult performs in-depth tests on billing applications. For this purpose we simulate up to 500.000 call scenarios to ensure rating and billing functionality and correctness. So loss of revenue can be avoided from the very beginning..." Our experts were assisting tele.ring with the implementation of a new billing system starting in the year 2000. Cellconsult was responsible for the design and execution of modular tests and the overall acceptance test. System patches and successive releases of the new software were also tested by us until 2002 Cellconsult supported the introduction of a new convergent billing system at Mobilkom Austria. For this purpose we developed a test-case repository and tools for the generation of test usage. Our experts performed end-to-end tests and the acceptance test for the first and several subsequent software releases Project System Integration Test (SIT) Goal of the project was the replacement of the current Hutchison3G Chordiant based CRM system with PeopleSoft CRM. The project has been delivered in two phases, phase one replacing all technical workflows for order management using OMQore and mapping current business process functionality available through DasCore/Tom and TOC onto the PeopleSoft model. Basically, every function, that has been available with these systems, has been replaced by PeopleSoft CRM. The second phase has involved the replacement of CCAA UI and Chordiant and the introduction of brand new functionalities such as hierarchical billing accounts. The testing process was the key for ensuring that all systems were integrated correctly and that process flows were integrated on a complete 'end to end' basis. The testing lifecycle could be kept up in every project stage from completion of business requirements to the development phase, see V-Model. Since the integration of PeopleSoft CRM was such a large endeavor, touching every part of the business support environment and communicating with most other business support systems was necessary to divide the test project into specific focused areas, mainly determined by business processes: Acquire & Register Customer Billing Account Management Service Management Mobile Number Portability Prepaid and Voucher Management Logistic System Management Reviews of functional specification have been one of the most important tasks for Cellconsult to prevent requirement defects from occurring. During the System Integration Test (SIT) a complete end-to-end test has been performed on an environmental level, ensuring that the test systems were communicating and working in accordance to the customer's requirements and specifications. The SIT approach has been based on the Chordiant centered environment. So Migration was an essential part of the project and has been tested in two phases: the test of the data migration itself and the test to guarantee correctness and consistency of the migrated data.
