In this paper we study Nolan’s life cycle models and explain it as an Instrument for IT Planning. In this world that competition is developed libertine, use of IT to access to competition advantage is necessary for all companies and is a more important key for companies' survival guaranty. However use of IT costs a lot, implementing unplanned IT probably burden heavy problems to companies. So the organizations try to decrease these threats and access to IT opportunities, using IT planning to implement IT/IS. Environment produces different opportunities and threats to companies. So organizations should recognize all their characteristics and use of opportunities to decrease threats. Although we have different models and methodologies that explain all of IT/IS implementation stages, but Nolan’s life cycle model is a more important and famous in IT/IS planning stage. In this article we explain Nolan’s life cycle model and finally we explore relationship between managerial styles, participation and system success in each stage of model.

In past two decades, Technology Roadmapping (TRM) became a popular technique at firm, industry and national level in developed countries. TRMs can take various forms, but generally comprise time-based multilayer charts linking technology developments to drivers and market trends. This article attempts to categorize different TRMs by presenting diversity of their applications, deploying levels, graphical formats, nature of technologies and different roadmapping approaches. Technology roadmapping is a flexible approach that can be used for various purposes. Although TRM has different shapes, but basic principles are the same. Thus process of developing a TRM is of special importance that present article attempts to explain different aspects of this process.
