Ad hoc development approaches in current huge developments may cause disastrous outputs. They lead to ambiguous communications, imprecise observations, brittle designs, inaccurate risk assessment, insufficient testing, uncontrolled change propagation and subjective progress assessment. For these controls over the huge developments, formally defined processes are needed. These development processes are required to provide visibility into the projects. Visibility in turn aids timely management control and mid-course corrections against the expected errors and crisis.
It helps developers to weed out faults quite early before they cause to entire failure. This also avoids cascading of faults into later phases where, accumulation of increased number of faults leads to failure.
A formal development methodology also helps to organize workflow and outputs to maximize resource utilization and to define everybody's roles and responsibilities clearly. Individual productivity hence increases due to specialization and at the same time the team's productivity increases due to coordination of activities. The adoption of a formal development process with well define unambiguous and complete policies will lead to the benefits of correct requirements to generate the correct product in order to meet the customer's needs preciously and inclusion of necessary features that will in turn, reduce the post-development cost.
Modeling methods in the past were not very formal affairs. Definitions were left to intuition, and there were many gaps. People with a formal methods background criticized these methods for software projects. They argued that the lack of rigor meant too much ambiguity. But the reality is that many people found that despite this lack of formality, the informal methods were generally more useful and fast resulting than the formal methods.
In practice, it seems that informality is an advantage. But for development projects of increased complexities and huge size, informalities proved to be the major reasons of failures. When the work was distributed in multiple teams, they could not interrelate and integrate their individual work products because of uncommon assumptions and bases of developments. Not following standards of work and strategically themes threw them into pits of failures and crisis.
Slowly, the developing industries realized the need of formal processes of development and they developed these processes as per their experiences in their fields. Further, the ongoing increase in size and complexities of the software projects forced them to come on a common platform to work. Now, when the development processes have crossed the boundaries of continents, organizations found the need to work with some formal standard definitions and development criteria in order to be able to integrate their individual efforts at any level or step of the project.
It led to redefining of processes into new improved standard processes. Many software organizations today are endeavoring to improve their software development processes to improve product quality, project team productivity and reduce development cycle times, thereby increasing their competitiveness and profitability. Software Engineering Institute SEI sparked the awareness regarding software process improvement, with the release of its original software process maturity model.
Following the advice of the SEI, many software organizations initiated software process improvement efforts to improve the quality of their products by improving the processes that produce those products. According to Kevin Hyde and David Wilson, CMM-based software process improvement may deliver both tangible and intangible benefits to an organization.
Survey-based research was conducted in the development organization during the early s to find out from software professionals if they believed the intangible benefits were being realized.
However, one problem that many projects face is that they create lists of bad requirements. Bad project requirements can delay the delivery time of the project, as well as result in a low quality of work. So, how do you stick to Thanks for sharing!

To gain true automated traceability requires a Requirements Traceability Matrix RTM since the RTM sits at the heart of every project and is a key deliverable within many development standards.
Artifacts at all stages of development are linked directly to the requirements matrix, and changes within each phase automatically update the RTM so that overall development progress is evident from design through coding and test. An RTM provides traceability between the software architecture and software detailed design, where the software architecture is refined into software units. Using the RTM, the impact of requirement changes and how they affect the system can be estimated.
When RTM becomes the center of the development process, it impacts all stages of design from high-level requirements through to target-based deployment.
Integrating requirements management and traceability with other tools saves time and avoids rework. Requirements are integrated with defect tracking, visual development and testing tools to jumpstart activities and provide each role on the team with a direct window into end user needs. For avionics systems development, having a RTM is essential to providing the levels of visibility that are required by the DOC standard. This standard requires not only that requirements be traceable down through the code and to the test cases and their results, but also that the reverse is possible.
By creating an RTM like the one described in Figure 1, it is possible to get the two-way traceability that the standard requires. Every software development standard across every industry incorporates requirements capture as a key component to the development process.
As a result, it is imperative that they be handled with appropriate care. It is not enough to have a requirements management process that stops at capturing the requirements from the original stakeholders. The process and tools used need to be able to handle the evolution of requirements from the original requirements through derived requirements.
To meet the objectives of the most demanding software standards which also happens to be best practice , it is also necessary to trace the requirements throughout the development process, down to the code and the software verification artefacts. Managing the complexities of this process demands the use of tools designed specifically to address these challenges. Creating and maintaining a Requirements Traceability Matrix RTM is key to ensuring that the evolution and application of the captured requirements are managed throughout the software development process.
