Case Study:Development of Content Management System for Sales Reps

The customer needed to provide its sales representatives a tool to demonstrate a variety of CD-based products. The online marketing group was looking for a web-based tool at the administration level to create "start-finish" tours and topic tours. The customer wanted the navigation system of the demo site to be flexible, powerful and user friendly. It was crucial to the success of the project that the tool was easy to learn and use because of the number and variety of products each representative would sell.
The other important objectives to be met were of:

Scalability — to handle increasing transaction loads arising from growing use
Flexibility — modify the look and feel without altering architecture
Portability — run on any commercially available, standard and open platforms
The Solution

Headway Solutions worked with the end-users to gather the requirements through a uniquely designed user interview process. After an analysis of the requirements, Hanu designed a content management web-site that allowed the customer to achieve its objectives.

Headway Solutions core contribution has been in the areas of requirement gathering and analysis; it involved study and assessment of the customer's needs and business processes. Hanu was able to design and develop the new system through its proven software development methodology.

Application Development: The detailed design and development was done with the project team which consisted–a Project Manager, a Technical Lead, a QA Lead and 4 Java developers. While developers were writing the code, the QA Lead prepared the System Test Cases. The System Test Cases were used to verify that all the requirements had been coded properly.
System Test: The system test was conducted at Hanu's offsite facility in NJ followed by the onsite customer acceptance test.
Deployment Support: The application was developed using the TomCAT application server and the MySQL database server. However the deployment was done on WebSphere and Oracle. During the deployment, the Hanu team worked side by side with the customer's deployment team.
Stress Test: Once the acceptance test was done, the customer proceeded to the Stress Test. Hanu supported the stress test through its valuable resources.
