Other than assets, the software process library also includes the process item, which includes the tasks and activities for software processes. The software process for an organization is used in developing, implementing, and maintaining the projects defined in software processes. In organization process definition, the organization follows a written policy for developing and maintaining a standard software process and related process assets.
Specifications of this policy are listed below. Annex A contains outlines of the contents of each document. Annex C contains an overview of the examples. Annexes D to S contain examples of the application of the templates. Annex T provides mappings to existing standards.
This standard supports test case design and execution during any phase or type of testing e. IEEE Std specifies a property-independent list of processes, activities and tasks to achieve the claim and show the achievement of the claim. It provides information to users of the other parts of this International Standard including the combined use of multiple parts. These claims are in the context of assurance for properties of systems and software within life cycle processes for the system or software product.
Assurance for a service being operated and managed on an ongoing basis is not covered in this International Standard.
This document focuses on the processes required for successful planning and management of the project's software development effort and for development of the software development plan SDP as a vehicle for representing a project's application of software life cycle processes.
The SDP is a top level technical planning document for a project which addresses technical management processes established by three principal sources the project?
This International Standard establishes a common process framework for describing the life cycle of man-made systems. It defines a set of processes and associated terminology for the full life cycle, including conception, development, production, utilization, support and retirement.
This standard also supports the definition, control, assessment, and improvement of these processes. These processes can be applied concurrently, iteratively, and recursively to a system and its elements throughout the life cycle of a system. This International Standard provides guidance for organizations in the application of ISO to the acquisition, supply, development, operation, and maintenance of computer software and related support services.
It does not add to or other wise change the requirements of ISO The measurement process is applicable to system and software engineering and management disciplines. The process is described through a model that defines the activities of the measurement process that are required to adequately specify what measurement information is required, how the measures and analysis results are to be applied, and how to determine if the analysis results are valid.
The measurement process is flexible, tailorable, and adaptable to the needs of different users. This document identifies a process that supports defining a suitable set of measures that address specific information needs. I could not find any theoretical reason of anything in software being hard to change. Any aspect of any software may be picked up to make easy to change.
Here a common practical problem arises. Efforts to make anything easy to change make the overall complex software a little more complex. This way, making everything easy to change in the software makes it uncontrollably complex. In fact, this is the complexity of the software systems that makes it hard to change. And its hardness to change gives a need of right decisions in early phases of the project. The sad part of software development is, while there are well defined theories to ensure the reliability of the hardware projects, the things are not so developed and mature about software projects.
But at the same time, it is mandatory to control its development through a well-defined and systematic process. 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.
