There are four main issues in implementing strategies: marketing, finance/accounting, research and development (R&D), and management information systems (MIS). For successful implementation, firms must market products well, raise capital, produce technologically advanced goods, and use information systems effectively. Low implementation rates are often due to improper market segmentation, overpaying for acquisitions, falling behind in R&D, and not using computers to manage information. R&D approaches include being first to market, innovating on successful products, or producing lower-cost alternatives. Finance decisions weigh debt versus equity, and pro forma analysis forecasts financial statements.
