Title : Sizing Software with Testable Requirements
Article summary
Without measuring the cost the project cannot be managed. In order to size the project the testable requirements can be used . The Testable requirements implies a new software measurement paradigm. There are some attributes and applications which needs to be identified.
In the industry the sizing measures are generally used to normalize the different sizing measures ,hence it can be compared . Further without a sizing the project the productivity statistics cannot be obtained. There are other factors which would be attributes when sizing progress measurement, earned value, risk identification, and change management.
Mostly widely used sizing measures are lines of code (LOC) and function points (FP). LOC is a measured by the size of the system which regard to numbers of programming states involved. This is a high dependency with the technology which has been used to build the system. Contrary to LOC, function points (FP) is a measure of by the functionality of the system. It is very much independent of the technology which has been used to develop the system. The use of testable requirements is as follows. As per the definition of IEEE there are six different types of requirements: functional, design, implementation, interface, performance, and physical. For the purposes of sizing,
each type of these requirements must be considered and each should have the same measurement standards.
Once high level functional requirements are identified, it could be decomposed into granular / precise requirements. The precise requirement can be considered as testable requirement. A testable requirement should be able to tested by one or more test cases.

...se requirement can be identified if the requirement can be tested by one or more test cases. This is a vague statement and need more clarity.
Overall the author has defined the testable requirements for sizing project well however it needs to be improved with more clarity and details.

Develop a test strategy for testing the entire application chosen in unit 3 for analysis and design. Keep in mind that testing that involves users should minimize their time commitment while obtaining essential information from their involvement. Specifically define roles, responsibilities, timing, and test strategy for each level of testing.

Finally, a Requirement Specification document is created which serves the purpose of guideline for the next phase of the model.
If given a chance to do things differently, we would first include the additional factors stated above as part of the evaluation criteria of the software providers. Also, as a last step to the process, instead of only relying on the demo by the providers, we would include a ‘pilot project implementation’ stage, where the provider integrates a piece of software to the existing architecture to be used by end users in production on a daily basis. This can provide a real test of usability, compatibility and can be used to evaluate critical measures such as fault tolerance.
FDA requirements for process validation in Section 820.75 of the Quality System Regulation (QSR). Performance of the process is inspected to obtain documented assurance that the manufacturing process successfully meets the pre-defined acceptance criteria. The activities in process validation that focus on machines, systems and equipment’s are called “qualifications”. They include: design qualification (DQ), installation qualification (IQ), operational qualification (OQ) and performance qualification.
It is a requirement that every major software development and implementation project includes three key stakeholders. These are enterprise customer, system integrator and software vendors. Most failures of the systems are contributed by these three stakeholders.
Early fixing of errors not only helps save cost but also helps in mitigating the various risks associated with software development and it also helps in improving and monitoring quality of the system etc. It has been proven that the cost to identify and mitigate the errors in the early stages of development of a software will be hundred times less than the cost of removing an error in the software system that has been distributed among hundreds of
Once customer requirements have been captured and analyzed, information of customer requirements needs to be translated into functional specifications and design. This activity involves marketing function, product designers and engineers.
In every project there are always some universal characteristics that will be shared. They all have a comprehensible and established purpose and very distinct life durations. Overall, all projects are doing something that may possibly be new or yet a one time endeavor but have explicit requirements which include; time, price, and performan...
Project managers must take cost estimates seriously if they want to complete software projects within budget constraints. After developing a good resource requirements list, project managers and their software development teams must develop several estimates of the costs for these resources. There are several different tools and techniques available for accomplishing good cost estimation.
After the systems planning is complete, the next course of action is the systems analysis phase. This phase includes defining the requirements of the system. This means that the team must conclude what the system needs to do in order to satisfy the users. This is done by forming a requirements...
A documentation framework is essential for any large project; hence, RUP describes how to document functionality, constraints, design decisions and business requirements. Use Cases and Scenarios, are examples of artifacts prescribed by the process and have been found to be very effective at both capturing functional requirements and providing coherent threads throughout the development and deployment of the system.
Quality is one of the most important components of application development and an integral part of the project process to ensure that errors are not made while
The team implementing the new system were required to do both functional and systematic requirements thus affecting the implementation of the new system
Information required to accomplish needs analysis in response to given deficiency is statement of problem presented in specific quantitative and qualitative terms and with enough detail to justify progressing to next step. Problem statement must reflect true customer requirements
