Project : Ethernet Order Automation

Ethernet Order Automation project is for automating the workflow of Ethernet orders. Before the automation, Ethernet orders are provisioned manually. Steps like finding the suitable NNI with required bandwidth, updating the LIMS inventory, and assigning the chosen NNI to service address are carried out manually. With automation these steps are automated. The goal of the automation is to achieve lot of improvement in turnaround time for delivering Ethernet service to the customers.

Project : Next Generation Work Management

Next Generation Work Management (NGWM) is a GWT based GUI application that makes order workflow provisioning easier. This enables provisioning users to identify what are the orders that are currently in a User queue. It shows the orders in Today Queue, Tomorow Queue and 2nd Day queue. Users can action these orders in the assigned priority. It is a role based application where a manager can monitor the status of orders in different queues of his team. Each user can do different things like closing jobsteps, launching inventory application, launching CORE application, launching some of eFlow screens to perform some provisioning tasks. So, this is a one stop application which enables the user to perform different provisioning tasks.

Responsibilities

• GWT migration from GWT 2.1 to GWT 2.3
• Removing GWT-incubator widget dependency and using GWT provided widgets
• Rewriting the work queue using CellTable

Project : EFLOW

Historically, the workflow behind Qwest's business processes has been managed within the applications directly supporting I.T.'s internal customers responsible for those processes. The applications tended to implement a small workflow engine internally to support their requirements, or, on occasion, integrated a stand-alone external workflow engine using that engine's proprietary APIs. This typically meant that it was challenging to consistently locate data about and report on something as fundamental as business process health, as no two APIs were consistent, nor were the databases behind them. Additionally, changes in the workflow design that required an external application's participation forced both sides in the exchange to write customized software to support these interactions.

eFlow was implemented with two primary goals in mind:

Bolster the infrastructure necessary to manage the workflow itself

Formalize the framework into which automated business operations and the web-based user interface components integrate which provide the highest probability for reuse, while simultaneously keeping the interactions as abstract as possible to reduce inter-component coupling.

Responsibilities

• Requirement Analysis
• High Level Design and Low Level Design
• Development of code for new requirements in Java
• Development of Web Services using J2EE
• Generating new XML and XML schema using XMLBeans
• Creating workflow using weblogic workshop
• Developing Java code for automated provisioning

• Writing unit test cases using HP Quality Centre
• Tracking defects using Defect Tracking Tool
• Status updation to clients and Senior Management
• Adhering to quality and timelines using IPMS

Project : Order Dashboard tool

eFlow is a workflow application and it doesn’t have any core user interface. So, in old days, for any trouble shooting, developers/prod support used to query different database tables to identify what went wrong with a particular order. This is a cumbersome process where people have to run multiple database queries and wire these results to understand the issue. Order Dashboard is a GWT based GUI application which provides one stop which provides all the details pertaining to an Order. So, people need not remember and run all those database queries to find out what was happening to the order workflow. Now, they can come to order dashboard and see all those results in an Order Dashboard screens. This saves a lot of time in troubleshooting.

Responsibilities

• Identify all the user requirements and designing screens to be shown in Orderdashboard
• Write Spring Services for the different Views
• Writing Spring Dao’s that are in turn called by Spring services
• Handling GWT to Spring integration and Spring service configuration
• Writing GWT screens
