The ?rst objective of this book is to discuss about the Component-Based Software Development (CBSD) as one of the advanced methodologies with the example of an inventory management system for Herat University, in Afghanistan. The second objective examines more closely whether CBSD can be a proper approach in Afghanistan, particularly in context of Herat University Inventory Management System (HU-IMS). The focus of CBSD is to assemble the previously-existing software components to develop new and large software systems. It emphasizes on the use of O? The Shelf (OTS) components instead of building a system from the scratch. The results of the book con?rm that considering CBSD when designing HU-IMS can be a proper approach in the Afghanistan scenario. However, the CBSD, particularly in Afghanistan context, has its own challenges and risks as all other approaches have. Since there are not many localized libraries and repositories available, the ?rst challenge is to ?nd and select the proper component which can be di?cult and time-consuming; and the second is the adaptation and localization of the found component.

The estimation of the software cost remains one of the most challenging problems in software engineering; as a preliminary estimate of cost includes many elements of uncertainty. Reliable and early estimates are difficult to obtain because of the lack of the detailed information about the future system at an early stage. However, the early estimates are really important when bidding for a contract or determining whether a project is feasible in terms of cost-benefit analysis. Estimators often rely on their past experiences for the prediction of effort for software projects. In this Book, we discussed a software cost estimation tool that helps commercial software-development organizations to effectively and quantitatively measure and analyze the software metrics based upon the functional requirements, operational constraints and organization?s capability to handle a project. The new cost estimation method is proposed for the iterative software development projects.

Is object oriented software complexity metrics important to a successful software development industry? And if so, how important is it, and why is object oriented software complexity metrics so important? Many readers and stakeholders often ask why object oriented software complexity metrics is important with respect to one’s measure, particularly in the software development process. Some people also want to know how object oriented software complexity metrics can impact overall quality of software, in addition to the impact object oriented software complexity metrics has on one's developments.

The success of software development projects depends highly on meeting the assigned schedule and budget of the project which are often defined in terms of a project plan. Estimation is the basis for planning; therefore, having a reliable way of estimating effort needed to perform the tasks is a must for a reliable project plan. Already in 1987, Samson, Nevill and Dugard, showed that there is a strong and direct influence of formal specification metrics onto the effort needed for implementation. Since then, there has been some progress in various aspects of formal specifications; the introduction of specification slicing methods, slice-based specification metrics, and methods for visualization of specifications has opened new ways for measuring properties of specifications with more metrics. Nevertheless, there hasn’t been much progress in the field of cost estimation using recent achievements of formal specifications. The main focus in this work is to examine if there is a correlation between formal Z specification measures and implementation related measures. In concise, this work tries to explain the correlation between the measures in specifications and code.

Component based software development is becoming quite popular in software development environment and just like object oriented metrics, component based metrics are also essential part of software environment. This study focuses on underlining the compatibility of object oriented metrics and component based metrics. The metrics for object oriented design focus on traditional and subsequent OO metrics which are focused on complexity, lines of code measurements that are applied to the class and design characteristics. These measurements permit designers to access the software early in process, making changes that will reduce complexity and improve the continuing capability of the design. Post design and development phase, the reuse and maintainability metrics help in better analysis and results. This book summarizes the various existing OO metrics, and does an evaluation of corresponding metrics, if any, for component based systems.

This dissertation investigates the factors that affect testability and testing cost of object- oriented software systems. Developing a software program which eases the testing process by increasing testability is crucial. Also, to assess whether or not the testing effort and cost consumed or planned is adequate or not is another critical matter this dissertation aims to answer by composing a new way to evaluate the links between software design parameters and testing effort via source-based metrics. An automated metric plug-in is used as the primary tool for obtaining the metric measurements. Our study is based on the investigation of many open-source projects written in Java to achieve our goals. By the help of the statistical evaluation of project data, we both propose a new model to assess testing effort and testability, and find significant relations and associations between software design and testing effort and testability of object- oriented software systems via source-based metrics.

Software is used everywhere in society, and is assuming responsibility for the systems that support the foundation of society. Nevertheless, software vendors are struggling to guarantee quality. To solve the problem, NEC Corporation devised a quality management method called "Software Quality Accounting", which has been built up and operated for over 30 years. NEC has been able to reduce and maintain the number of post-release defects to less than 5%. Quality accounting is based on the idea that defects should be seen as “debts”. It is more economical to pay off debts early, before they grow due to accrued interest. Software defects are similar in the sense. This book introduces the methodology of "Software Quality Accounting" and how to apply it. And three actual examples of quality improvements made through the application of software quality accounting are introduced. Also, a supporting framework, developed to help make efficient use of Software Quality Accounting, has been contributing to increases in quality as well. Based on the results, this book identifies the primary factors of success with high quality software development and an overall perspective.

Planning of software projects has become complex and challenging more and more as time has passed. Software project managers are dealing with issues such as rapid change of customer demands, dynamic advancements of hardware platforms and intangible nature of software. Development effort estimation plays a vital role in software project planning because accurate estimation is needed when dealing with the complexity of software projects. Numerous researches have been conducted to improve the accuracy of development effort estimation in recent years and various methods have been proposed in this field. Extensive diversity of existing methods and the lack of unified investigation of which, have inspired us to write this book. We have tried to collect the most significant studies in terms of software development effort estimation based on the latest findings in this area. It is expected that this book can be an initial reference for researchers who want to work on the mentioned field. This initial reference might help researchers to have a simple overview of available effort estimation methods in software projects.

Component Based Software Engineering (CBSE), which deals with the software construction by components'' assembly, is an extension of Software Engineering. A conventional Software Engineering process deals with ‘Creation of a new system'' from scratch whereas a CBSE process does the same through ‘Composition making use of existing components''. This basic change in nature of development indicates that the conventional software processes need to be redefined in order to make them applicable to CBSE. This work purposefully considers software processes and maturity models for CBSE. A meaningful part of this work attempts to capture the idea of dependence and demonstrate a method for the dependence analysis among software components in a quantitative manner. Necessary discussion on composability issues in CBSE has also been elaborated as part of this work. The researchers and practitioners dealing with CBSE can find the discussion, observations and conclusions reported herein useful. It may serve the purpose of study material for graduate courses on CBSE processes, dependability and composability issues.

In modern time users demand powerful and reliable software. Companies want to control software complexity and development process. Most computer scientists and experts agree that the complexity of program will increase in future. But it takes more time to define and measure complex program. The objective of our work is to provide creating new method that helps organizations and project managers to determine quality of program without seeing source code. Developers, project managers, testers and product improvement teams should get our tools helpful in measurement of software metrics and collecting data. There are many reports or analysis tools that measure the quality by seeing source code.The determination of software quality factors based on 318 source code from 36 countries. The working principle of tool is guided by Halstead metrics and LOC metrics. In modern programming the using of this types metric is not so widely. But in book it is seen that the quality factor can be determined by using the these metrics.

Despite the emergent of a large number of software quality improving techniques, in practice people tend to use the value-neutral approaches in software quality analysis and achievement. Based on the literature survey and empirical results, the traditional views of software quality often lead to stakeholder unsatisfactory outcomes even if sometimes an almost zero-defect product is delivered. The reason is that different systems have different success-critical stakeholders, and even for the same system these stakeholders may depend on it in different ways. There are no universal one- size-fits-all software quality metrics to optimize and we need to balance stakeholders’ different value propositions on software quality attributes. Thus, there is an increasing need for stakeholder/value based approaches to software quality modeling and its achievement monitoring and control. A Value-Based Software Quality Analysis framework is being suggested through this book, which consists of the definitions, metrics, model, and process to address various aspects of software and system quality analysis and achievement using value-based approaches.
