Secondly, for each block of the matrix that the firm is in, determine what solutions are available from which vendors. Third, analyze the products in terms of their costs and benefits to the firm. Next, identify any risks involved with using the product. Then, seek the help of potential users to identify implementation and training issues.

In the waterfall method, the SDLC tasks occur sequentially, with one activity starting only after the previous one has been completed. The analysis phase nails down the requirements, and at that point the developers estimate the time and resources needed to complete the project. Different people may be engaged in each task, and they hand off their work to the next team when their part is done. While the waterfall method estimates time and resources needed based on the analysis of requirements, the iterative methods do the reverse. Iterative methods focus on the time available until the next release, or iteration, and the development team determines how many of the requirements it can deliver in that timeframe.

High-quality information is accurate, precise, complete, and consistent. It does not have flaws such as spelling and grammatical mistakes, omissions of important numbers, addresses without zip codes, quotations without the author's name, inconsistent formatting, etc. High-quality information is also marked by up-to-date information. In stock trading, for example, information that is biased lacks objectivity, which reduces its value. Thus, high-quality information is objective. Such data is also free of repetitive information.
