MMô fast-growing imageFast development model (RAD-Rapid Application Development) is ascending model with extremely short development cycle. To achieve this goal, RAD development method based on component-base system with the use of the appropriate component. RAD suitable for the information management system.Pattern twistedThis model was built by Barry Boehm, put emphasis on risk analysis and review of the plan to solve them, through many cycles of the serial was repeated in a row based on the nature of the pattern repeats.In this model, analyzing and solving the problems of high risk have focused on specific aspects of each design rather than relying on the handling of the issue in a general way.Figure 7 illustrates this pattern with the recurring period according to the rotation cycle, in which each cycle includes4 the stages are as follows:-Identify quality goals for the product being made, at the same time determine the choice to buy, reuse or the design and implementation of the components of the system.-Analysis of the choice and the risks that can occur. This is done by many different activities through modeling or simulation.-Development and product testing at the next level based on the results of the orientation specified in Figure 2 stages (risk analysis)-Uncensored all the results of the stages that occur before and planning for the next iteration cycle.
