The process continues from step2 until the entire program structure is built. The top-down strategy sounds relatively uncomplicated, but in practice, logistical problems arise. Divide the product and/or its components and rearrange them to form a new product. Using this tool forces consideration of different structures, either on the level of the product/service as a whole, or on the level of an individual component. Dividing a product to many pieces gives the freedom to reconstruct it in many new ways – it increases our degrees of freedom for working with the situation. As the new products are based on the old ones, no major changes are usually required in production. The simplicity of the sit-in protest was critical to its success. As a protest tactic, the genius of the lunch counter sit-in was its ability to convey a clear, powerful message through such a simple act. The protests were easily replicated. New groups of students could be readily drawn into the movement. A phone call from a friend or family member, a picture in a newspaper, a report on the radio was often all that was needed to plant the spark in another city. Through the winter and spring of 1960, students across the South performed the same basic routines again and again. Put on nice clothes. Gather for a discussion of logistics, some final words of inspiration, perhaps a prayer. Then walk into a local drugstore or department store, sit down at the lunch counter, and request service. Staging a sit-in protest did not require elaborate planning (although as the sit-in movement unfolded, civil rights organizations and lawyers played an increasingly significant role). Just a handful of people could initiate one, as the Greensboro Four showed the world. The remarkable spread of the sit-in protest across the South was made possible by the accessibility and replicability of the protest action itself. 58

This is the tendency to view objects as a whole, as a gestalt, which often makes it difficult to imagine how the product could be reorganized to look differently. For example, why do TV controls always have to be on the lower part of the TV set? Would it not be easier if they were on the upper part? However, the limitation of this approach is the most important subsystem i.e. UI is tested at the last. #3) Sandwich Approach: Function follows form is a principle associated with classic architecture, and it is also being used in government buildings. The concept of this principle means design created according to a shape, but do not consider its function at initial stage of architectural design.One of the important elements of SIT is to characterize the system and environmental variables. After having defined these variables, the participants are asked to examine the correlation between them, and to examine the impact of manipulating one or more of the product variables on the potential use of the "new" product; how such a change affects the correlation between the product and the environment and who may want to use such a product.

The execution of the above diagram will be module A, module B, module C, module D, module E, module F, and module G. All modules are integrated in advance, and the entire program is tested as a whole. But during this process, a set of errors is likely to be encountered.The "function follows form" principle is applied as an overarching framework to focus the application SIT's thinking tools. Note: If the top two levels of program structure are integrated Top-down, the number of drivers can be reduced substantially, and the integration of builds is greatly simplified. Big Bang Approach At the heart of SIT's method is one core idea adopted from Genrich Altshuller's TRIZ which is also known as Theory of Inventive Problem Solving (TIPS): that inventive solutions share common patterns. Focusing not on what makes inventive solutions different– but on what they share in common– is core to SIT's approach. Maurice C. Daniels, Saving the Soul of Georgia: Donald L. Hollowell and the Struggle for Civil Rights (Athens, GA: University of Georgia Press, 2013), 107. Both TRIZ and SIT share a basic assumption - that one can study existing creative ideas in a field, identify common logical patterns in these ideas, translate the patterns into a set of Thinking Tools, and then apply these Thinking Tools to generate new creative ideas. In spite of the commonalities, SIT strongly differs from TRIZ in several important respects, having to do mainly with its practical application. [7] From TRIZ to SIT [ edit ]
