UST helped global retailer ramp up productivity by 26.7 functional points with managed capacity support

The company needed help maintaining its aging, mission-critical warehouse management applications so IT leaders could focus on designing and developing a modern replacement system. UST's expert resources quickly ramped up and achieved a productivity level of 26.7 functional points per man-month.


This American multinational company is one of the leading big-box retail chains in the world. With more than 750 locations across the globe, the company employs more than 300,000 people and generates annual revenue of nearly $250 billion.

Provided managed capacity IT resources to maintain existing applications skillfully

At the same time, the company's IT leaders focused on designing and developing the replacement system.


Saved approximately 1/3 of costs with offshore managed capacity model vs. onsite support

By going with this flexible off-shore managed capacity model, the company saved about a third of the cost of an onsite engagement. The UST team provided quick responses to support tickets, completed all scheduled maintenance tasks, and achieved these metrics:
