Secret Classified Ad Formula Sucks in Prospects Like a Tornado! Part 1 ------------}This report will reveal a classic formula for writing rivet pulling classified ads that will skyrocket your sales.It assumes you have a basic understanding of where and how classified ads should be used for best results.But just in case, here are two hard and fast No-No's that many people ignore every day:1-Never use Classified ads to sell things for money!There simply is not enough space in which to justify the cost, no matter how minimal.2-Classified ads should not be about you, your company or your product!Apple Widget, the finest widget made. Trustworthy and Honest American Craftsmanship. Order yours today!WRONG!The ad should tell prospects what your product will do for THEM!For maximum results, Classified Ads shoul Phase II [SYSTEM PLAN / Justification] {-----------------------||----------------------------} Phase III [OUTLINE DESIGN / Confirmation] {-----------------------||----------------------------} Phase IV [DETAIL DESIGN / Confirmation] {-----------------------||----------------------------} Phase V [CODING/ Unit Test] {-----------------------||----------- The purpose of this model is to introduce modus operandi into the system design process; as a skeleton for system development it advances consecutively through a succession of phases, preliminarily with system feasibility analysis and concluding up to system release and maintenance. The name “waterfall” portrays system progress flows from the top to the bottom, like water falling down steps in a waterfall panorama, one phase at a time towards the bottom in a cascading effect. In the present day, the waterfall model is considered classical and conservative system type model; however, it is indispensable for a fundamental understanding of system development in IT project systems management. In the waterfall model, system design is broken down into a number of linear and sequential stages, in which system evolution is seen as flowing progressively downwards, through the phases. The waterfall model has distinct goals for each phase of development. In this development method it is not allowed to journey onto the succeeding phase until the operation of the preceding phase has been accomplished. The output from each phase formed the input to the next phase; therefore, each phase had to be accomplished in turn to maintain the linkage between the inputs and outputs. A detail waterfall model can be represented as in the following system development life cycle: Phase I [SYSTEM FEASIBILITY / Justification] {-----------------------||----------------------------} Phase II [SYSTEM PLAN / Justification] {-----------------------||----------------------------} Phase III [OUTLINE DESIGN / Confirmation] {-----------------------||----------------------------} Phase IV [DETAIL DESIGN / Confirmation] {-----------------------||----------------------------} Phase V [CODING/ Unit Test] {-----------------------||------------ The name “waterfall” portrays system progress flows from the top to the bottom, like water falling down steps in a waterfall panorama, one phase at a time towards the bottom in a cascading effect.

Within this model, the terms confirmation and justification have specific meanings: Justification means validation or inspecting whether the result is fit for the operational mission, that is, checking whether the correct product is being build or not. Is the product correct? Confirmation means verification or inspecting the link between a result and the specification for the result. In other words, a check that the result is being constructed in the correct manner. Is the system structure correct? The process of building the systems product flows phase to phase with very little interaction in-between two stages, apart from transfer of outputs and inputs between them. The phase progression sequences enforce discipline as every phase has a specific start and end spot, and progress can be categorically acknowledged. Within more modern system design projects, the water model is in use to mean any chronological representation that is divided into successive phases and which pursue the common structure of the original model. Here, the naming of the phases is not vital, and suitable names can be used for the particular project being undertaken. The waterfall model retains that system and should move to
