That is not to say that these external pressures are to be ignored. The entrepreneur needs to be apprised of the possible impact of government, technology and so an, at all times. However, these are slower moving events and have long-term rather than short-term applications, if any, to the venture. Pending legislation to impose pollution controls can take years before new business may have to worry about it. The emerging technology can have an impact quickly, but is also dependent on other conditions. Electronics and computer-related products and series have three- to four-mouth turnarounds and are the most volatile of all business endeavours. Yet there is a time period to clear the retail system to inventory, which, in association with advance warning, can give up to one year before the entrepreneur may be faced with a new product. Hopefully, it is the venturist’ s new technology that is emerging into the market.
