Juzahn Both are tried to see if they are well suited to each other. It was especially designed for government departments and their external providers of software, where there was a great need for Information Systems and hope to improve their IS by using a disciplined engineering method. Evaluation of the implication and benefit of each proposed option. Proposal of new methods and techniques in order to describe processing and data structures. This fact can lead to the problem that the end result deliver does not meet the business requirements at the point of time when it is delivered.

It uses an extensive 6-step procedure to establish how an information system should be updated or created. This complex and long analysis comes with numerous advantages as portrayed below. This reduces the likelihood of any data being misinterpreted at the early project stages. This can happen in systems where inadequate analyses are carried out on poorly imagined designs. Furthermore, because SSADM is normally used regularly, many people who are involved in that project will comprehend the process.
The use of familiar processes prevents the requirement of training new staff, saving time and money. Highly practical When used together, the many SSADM stages form a beneficial set of real-world prescriptions that consider real challenges and conditions. This enables the designers to realistically think about the recommended information system.
Key stages of SSADM include feasibility study, where the designer should establish if the recommended system is attainable and the study current system demands that current systems are reviewed.
This ensures that all recommended changes are useful and necessary. Coherent design A coherent design of the required tools for designing the system makes the work of designers easier. SSADM helps to present such a coherent and logical presentation. Because of its logical nature, it emphasizes data analysis and comprises of techniques like data flow programs.
Organizations must add information or data analysis into their systems as it will enable them to also consider alternate methods of acquiring desired information. SSADM requires very large resources for proper implementation since every stage should be thoroughly completed before taking the next step. This can cost lots of money and also time.

ADVANTAGES OF SSADM METHODOLOGY PDF
Developed in , this evaluation method uses data flow modeling, logical data modeling and entity event modeling to verify whether or not a plan for an information system is sound. This six-step process has remained an important part of system development because of its multiple advantages. Controlled Creation SSADM is an extremely controlled method that has a standard methodology for all parts of the creation process. If the process is followed to the letter, there is little chance that the project will have any unforeseen problems.
Benefits Of SSADM
Waterfall Model The waterfall model is one of the most traditional and commonly used software development methodologies for software development. This life cycle model is often considered as the classic style of the software development. This model clarifies the software development process in a linear sequential flow that means that any phase in the development process begins only if the earlier phase is completed. This development approach does not define the process to go back to the previous phase to handle changes in requirements.
Advantages of SSADM
An information system is the combined working of people and specific set of hardware and software for the purpose of enhancing the operation of an organisation. SSADM is like an instructional manual of step-by-step guidelines the analyst can follow. SSADM guides analysts through the process of developing information systems for an organisation. Method SSADM has detailed rules and guidelines that lead the analyst from one suggestion to another regarding the proposed information system.
