Software Process Improvement Process
Abstract— Software process improvement is the need of this era. As the software industries grown up the need of process improvement increase rapidly. Software Process Improvement (SPI) includes a set of doings that will lead to an improved software process, and as significance, higher quality software provided in an anticipated time period. Different improvements have been made in the development of software process improvement (SPI) standards and models, e.g. capability maturity model (CMM), more recently CMMI, and ISO’s SPICE.
This paper elaborates the overview of software process improvements, its need and different models used in the process of software quality. There are lots of Software Process Models those exist in software industry

SOFTWARE PROCESS [1] In software engineering there are many definition of software process. “The software process is the set of steps and method that used different tools to produce high quality products.” The objective of software process is to provide an appropriate organizational constancy and good control.
The software process is a framework of tasks to manufacture excellence software. (R.S. Pressman)
Many example is observe in software engineering field like The Software engineering development process (SDLC), Requirements engineering process, Quality assurance process ,Change management process, Design process.
"Process is a set of organized resources and activities which convert inputs into outputs. Resources may contain human resources, funds, facilities, tools, procedures and method" [ISO 9000-1 1994].
III. SOFTWARE PROCESS IMPROVEMENT
The objective of software process improvement is to apply organized steps of a method to improve development process like Quality improvement, schedule reduction and Cost reduction. An organization should evaluate their structure and process to identify the weakness and success of software development process and take action to improve software

SOFTWARE PROCESS IMPROVEMENT MODELS [7]
All over the world many software companies has aim to improve their software development process, for this purpose they used many improvement models like CMM, ISO 9000 (quality standards), TickIT, Trillium, BOOTSTRAP and so on
VII. CMM [8]
CMM was developed as a result of research that was funded by United States Department of Defense. The purpose of this model was to improve the processes with the aim of collecting data for decision making and use this data for continuous improvement of the future. Carnegie Mellon University establishes Software Engineering Institute on the base of CMM.
The original CMM was developed for software development in general. As the need arose, it was developed separately for System Engineering, Supplier Sourcing, people and other dimension of software development.
All these CMM were separately defined and included set of practices for all these disciplines. They all called for continuous improvement and collection of data.
CMM has 5 maturity levels each level has set of key processes; doings that, when executed together, accomplish a set of goals. Figure: 3 Maturity Level of CMM [8]

755 Words | 4 PagesIn this modern world the need for designing and developing an application with good secure features is very high. I have also learned what an error exceptional handling is and why is it important in code review. I have also learned that in developing a software product or in the software development life cycle process, a software product must be teste in earlier stages and very frequently. This recalled my knowledge of secure software development life cycle. One must know the importance of secure software development life cycle.
Quality-Guru Case Study
370 Words | 2 PagesHealthcare leaders seeking to change the current system must work to maximize value for patients—that is, increasing access and achieving the best outcomes at the lowest possible costs. This transformation is not a single step but an overarching strategy of quality improvement (QI). Dr. Robert Janet, MD is the Medical Director at Mount Auburn Independent Practice Association, and a leader in the field doing exactly this: challenging current practices in order to improve both the physician-patient relationship and the physician experience through innovation and collaboration. I consider Rob the quality-guru in my life. With his patients, he helps them make changes by altering their outlook; they need to have enough humility and self-awareness

The purpose of the therapeutic recreation accountability model is to help a therapeutic recreation specialist create a connection between the patient outcome that will benefit their treatment in the future. The outcome of the patient will go through program planning, client assessment, or quality improvement into a comprehensive system that is efficient and easy for both the patient and TR to understand and be at the same phase. Name three characteristics of quality client assessment in therapeutic recreation services. The three characteristics of the quality client assessment in therapeutic recreation services are: • program should be equivalent to

In ASDA case, in order to make changes in regard to the poor quality and customer satisfaction, Archie could utilize and implement a total quality management process. Additionally, he could use a balance score card and run operations lean so that there would be a solid balance between the financial objectives and the internal/ external business processes. The balance between non-behavioral and behavioral elements can lead to success (Spector, 2013, p. 6). Next, to address the poor communication, the organization could change this behavior by linking and coordinating the vital value chain activities of the organization such as purchasing, delivering, sales etc.

Samsung Manufacturing Strategy: Process Strategies
732 Words | 3 PagesProcess Strategies The process strategies, for such a large manufacturing company, would need to be varied. The production process type would be determined by the product life cycle stage at that time (Thayer 2004).Product life cycles for items such as smartphones and tablets do not generally follow the standard life cycle stages. The maturity stage can be interrupted by discontinuation or irrelevance of a technology, which recommences the cycle (Giachetti & Marchi 2010). Incidentally, during the product life cycle of these items, a cyclic improvement of both process and product is required to stay in contact with market changes.
