Dow is a leader in science and technology, providing innovative chemical, plastic and agricultural products and services to many essential consumer markets.

The project included a joint team of Dow and Accenture employees working together to create systems that accommodate multiple mergers and acquisitions, as well as eCommerce, customer relationship management and supply chain projects.

During my stay with the DOW Chemical project, the main focus was to integrate the systems between DOW chemicals and Union Carbide Corporation. In 2001, Union Carbide became a wholly owned subsidiary of DOW Chemicals. With this merger, there were multiple applications, which need to be integrated or replaced. Accenture was responsible making this transition happen as soon as possible and with as little impact to business.

Another focus came up around June 2001 to July 2002 wherein the Information Systems Department of DOW was going for CMMi accreditation. There where many initiatives to improve the quality of IT, including coming up with systems to track quality and using Six Sigma measurements as metrics and performance indicators.

Role in the project: Traveled to US to Michigan and Southfield to study the DOW client server systems and then to Houston to look at the Union Carbide equivalents. The applications assigned to me were on the supply chain and material transportation.

During June 2001 to July 2002, designed and developed a quality tracking system for the Information Systems (IS) Department of DOW which uses function point counting and Six Sigma to track and measure the quality of work coming from the IS department.
