Integration and System Testing: This phase is highly crucial as the quality of the end product is determined by the effectiveness of the testing carried out. After that these modules are tested by writing some overhead code to check the interaction between these modules and the flow of intermediate output.Ĥ. Small modules are tested in isolation initially. If the SDD is complete, the implementation or coding phase proceeds smoothly, because all the information needed by software developers is contained in the SDD.ĭuring testing, the code is thoroughly examined and modified. Implementation and unit testing: During this phase, design is implemented. All this work is documented as a Software Design Document (SDD).ģ. It defines the overall software architecture together with high level and detailed design. Design Phase: This phase aims to transform the requirements gathered in the SRS into a suitable form which permits further coding in a programming language. It describes the "what" of the system to be produced and not "how."In this phase, a large document called Software Requirement Specification (SRS) document is created which contained a detailed description of what the system will do in the common language.Ģ. Both the customer and the software developer work together so as to document all the functions, performance, and interfacing requirement of the software. Requirements analysis and specification phase: The aim of this phase is to understand the exact requirements of the customer and to document them properly. This model is named " Waterfall Model", because its diagrammatic representation resembles a cascade of waterfalls.ġ. The developer must complete every phase before the next phase begins. The steps always follow in this order and do not overlap. Go to other pages of and see what else you can add to your landscape drawing to revitalize it and make it even more interesting.Winston Royce introduced the Waterfall Model in 1970.This model has five phases: Requirements analysis and specification, design, implementation, and unit testing, integration and system testing, and operation and maintenance. So, try to draw this wonderful natural phenomenon of some other shape using the steps that you observed above.Īlso try adding some additional trees, animals, or people that are at your painted cascade. Paint the water in light blue, the rock in gray and the grass in shades of green.Īs we said in the introduction, this instruction contains the basic principles of drawing waterfalls. Now prepare your favorite pencils, paints or felt-tip pens to paint the waterfall. Next, create diverging waves around the falling water. Now, using a series of vertical lines, create the texture of the water flowing down. You can draw grass, as in the example, drawn by the artists of, or add some kind of trees. Let’s give some live our waterfall by sketching some grass around it. Around it, outline the pond where water flows from the waterfall. Try either to repeat everything as in our example or come up with your own form of rocks under the waterfall.Īt the bottom, depict a foam formed from a drop of water. This stage will be a little more complicated because here we depict rocks. Do not try to make these lines perfectly straight and smooth. Now let’s depict the waterfall itself, or rather its contours using two very light lines. The upper line is the upper edge of the waterfall, and the lower line is the lower edge. Let’s start drawing a waterfall from the simplest – draw two simple and not very even lines.
