Hence, they are also readjusting themselves to the new market economy. Major suppliers of IT, such as Microsoft and IBM, are finding other ways to attract consumers.

The following explains three rules to which a company should take heed. 1.Spend less. Big investments rarely give you good financial results. It is harder to gain an advantage now because IT is so widespread. A company should be aware of their investments so as to prevent enormous debts. 2.Follow others, don’t lead. According to Moore’s Law, the longer you wait to make an IT purchase, the more you will get for your money. Waiting can also decrease your risks of buying useless things.

But what is more important is the ability to distinguish essential investments from unnecessary spending. Companies should be willing to explore cheaper solutions. Walmart and Dell purchased the right technologies after they ruled out the useless ones. Smart thinking is the key to success in today’s market economy.
