AppAdvice has teamed up with iMBA Online in order to offer you a chance to win one of five (5) promo codes for iMBA for iPhone and iPod touch ($1.99).

Created by Harvard alumni and based on the Harvard Business School’s Case Study Method, iMBA brings a portion of the Harvard Business School’s Master of Business Administration program to users through an extremely affordable, plus easy to follow and reference management tool. The iMBA app contains 50 of the world’s most popular management concepts written in a manner that everyone can understand. These tools are important for everything involving decision making, anything from expanding an already distinguished company to coaching the local youth baseball team.

iMBA‘s concepts are formulated from surveys of existing Fortune 500 companies and longstanding military tricks. These proven theories are broken down into two categories, Marketing and Strategy. Each notion is broken down even further into background, application, case background, and case study. To further help apply these concepts to your own organizations, the Application section is divided into individual elements.

The app is separated into four main navigation portals. The main Index allows hierarchical navigation of all topics and concepts. Filter down step-by-step within categories by using the Tools section or find topic related tools by utilizing the Tags section. Search for tags using the Search function, and quickly access those concepts you find important with the favorites system. Looking to broaden your management horizons in general? The Tool of the Day presents a user with a random concept they can apply to their particular situations.
