Needs for drastic improvement of software development productivity and quality model) covering all aspects and all life cycles of the project should be created.http://www.omg.org/docs/ad/99-02-05.pdf. := To build the information system * There exists a unique information model for specific process / methodology or individual project. * Implementation of the model is resulted in the information system. This brings each project its own software development system. * Domain Specialist of the software development domain - also interoperability between various CASE tools * MOF standardizes the repository metamodel. * XMI facilitates the information interchange between tools. * CORBA, DCOM support the distributed objects environment. * It is a generic model, which contains the types of the elements common to almost all software developments. * It can be easily specialized and adapted to satisfy the specific process / methodology and/or individual project needs. * Resulted model (i.e. UML model diagrams) can be easily implemented on a repository as main part of the project's own information system. * It is constructed by the following packages: Generic Reference Model is specialized in various ways and the result is implemented as the specific Software Development System . One of our targets to be modeled as typical process/methodologies. BOAD is compliant to UML It focuses on the effective UML usage, such as : * In which phase and which diagrams should be used ? * In a lot of constructs within each diagram, which elements and in which phase should be actually used ? * Not to use too many kinds of diagrams and elements, as far as possible. - As the project plan will ... o compete in the digital economy, companies must be able to de-velop high-quality software systems at “Internet speed”—that is, deliver new systems to customers with more value and at a The Internet environment intensifies software development prob-lems by emphasizing shorter cycle times.http://www.sei.cmu.edu/programs/acquisition-support/publications/levine.pdf. Developing software at Internet speed requires a flexible development environment that can cope with fast-changing requirements and an increasingly demanding market. Agile principles are better suited than traditional software development principles to provide such an environment. High-visibility Internet software leaders such as Microsoft and Netscape have adopted agile development methods for this new arena. Whether these practices support traditional software engineering principles and will result in high-quality software isn’t clear, however. On the basis of our multiphase study of 10 software development organizations over three years, in conjunction with findings from a Discovery Colloquium on best practices for fast-paced software development, we examine how and why practices used to develop soft-ware at Internet speed differ from traditional Working at Internet speed changes how software development is organized. Methodological perspectives represented a broad spectrum: from adherents of agile methodologies to ad-herents of traditional software process disciplines. Participants joined one of several breakout groups dedi-During the first phase in Fall 2000, we conducted detailed case studies of Internet software development at 10 companies in two major metropolitan areas. Our objective was to under-stand how and why Internet-speed ... The CHART program relies on communication, coordination, and cooperation among agencies and disciplines, both within Maryland and with neighboring states, to foster the teamwork necessary to achieve transportation management goals.http://www.chart.state.md.us/downloads/readingroom/chart_ii_documents/CHARTIISoftwareDevelopmentGuide10Final013003.pdf. Section 1 presents an introduction to the CHART program and the research methodology used in developing this Guide. It also includes information on the usage of various CHART II tools and identifies the typical CHART II software development work products. The project team conducted interviews with new CHART II software development staff, as this group was utilizing the existing CHART II documentation to develop new system functionality. Using experience gained from previous traffic management software implementations, SHA provided an initial set of requirements for CHART II that were validated and enhanced by an extensive business architecture development effort. The process used to develop the CHART II software included extensive review and consultation with the users of the system. Farradyne software development team has been investigating the use of an open source ORB, but MDSHA has not yet decided to move towards a new ORB product for CHART II. It is strongly encouraged for CHART II software development teams to consult with MDSHA, who may have ORB licenses available for use. An abundance of documentation has been produced during the course of CHART II software development, representing both past efforts and those activities currently in progress. ICD designs business processes at a detailed level and develops new application software on a custom basis. Other FMS systems could continue to ... Capital projects related to internal use of software are approved by a capital budget process.http://www.yale.edu/ppdev/policy/4203/4203.pdf. All computer-related assets of the University (including software, infrastructure applications, systems) are eligible to be capitalized if: they embody a probable future benefit for more than 2 years that involves a capacity, solely or in combination with other assets, to contribute directly or indirectly to future cash flows and/or service potentials or extend the Policy 4203 Accounting for Software Costs, Computer Systems, and Business Process Reengineering 4203.2 Systems Development and Acquisition A. Software Development for Major Institutional Systems Costs incurred for the development or acquisition of software for major institutional computer systems (such as procurement, payroll, student services, general ledger and others), including software upgrades and new releases, may be capitalized if they: are an integral part of the system, or This stage generally encompasses the following activities: 1. design of chosen path, including software configuration and software interface; 2. technical software coding; 3. installation of hardware; 4. testing; 5. data conversion (programs and tools only); 6. other related costs; 7. equipment. Purchased Software: The cost to purchase software. Interest expense: Interest expense will be capitalized on software development projects consistent with the University’s policy for interest capitalization on long-term projects. General and Administrative Expenses: General and administrative expenses are not to be allocated and capitalized as part of the cost of a software development project. ... If we as communicators approach developing help systems in the same way we approach writing paper documentation, we miss the advantages of using software development methodology.http://www.stc.org/confproceed/1998/PDFs/00008.pdf. Help systems are software, typically consisting of text files, macros, wizards, and more. Users do not distinguish between software systems and their help components; both form a single impression of the product in the user’s eyes, good or bad. Help systems, while having their own User Interface (UI), must also stylistically blend with the UI of the rest of the software. Software engineers write, compile, and test on a day-to-day basis; help developers write, compile, and test on a day-to-day basis. Since a help system is software, we must employ the same development discipline as the programming staff. The results of the “no time to write a design document” mentality are the same as the results of developing software on the fly: So what can we learn from software development methodology? The waterfall software development method is a classic, tried-and-true method that has been proven effective through many years of software development. The waterfall software development method looks something like this: The process begins with a definition of system and software requirements, proceeds through design and coding phases, and concludes with increasingly comprehensive test activities. These reviews are attended by representatives from each department involved with the product, typically: Marketing, Sales, Software Development, Hardware Development, Tech Pubs, Validation, QA, Customer Service. These reviews are attended by the same departments ... At its core, the value of software is derived not only from its ability to increase productivity and efficiencies, but also from its resiliency to attack and always performing at needed levels during times of both crisis and normal operations.. This task force’s central thrust is towards establishing a world with robust software security, where users continue to benefit from software innovations. Together these sub-groups have focused their mission on increasing software security through: ∑ ∑ ∑ ∑ enhancing the education and training of present and future developers to put security at the heart of software design and at the foundation of the development process [Education Subgroup]; developing and sharing best practices to improve the quality of software, as well as the RECOMMENDATIONS The Education Subgroup focused on present and future developers and recommends that 1) security become a core component of software development programs at the university level with sufficient resources to build the academic capacity to improve secure software development, and 2) supports the creation of an industry-led certificate program for security professionals and The Software Process Subgroup authored a report focused on best practices for putting security at the heart of the software design process. Principle recommendations listed below are focused on broadening use of the current most promising available practices for developing low defect secure software, to produce definitive studies that compare the relative effectiveness of available security practices, and to work within the software industry to achieve widespread use ... To simplify the development of these applications, Intel offers the Intel® NetMerge™ Enhanced Software Development Kit (SDK) for use in conjunction with its open, standards-based Intel NetMerge Call Processing Software.http://www.intel.com/network/csp/pdf/4048ds.pdf. The Intel NetMerge Enhanced SDK builds on basic Intel NetMerge Call Processing Software server functions by providing a more intuitive higher-level telephony programming interface that shields developers from the variations in the behavior of different telephone switches. Intel® NetMerge™ Enhanced Software Development Kit (SDK) For example, depending on the telephone system being used, the basic Intel NetMerge Call Processing Software programming interface sometimes requires a programmer to specify the precise telephone call on which to operate. The call is identified with a call reference identifier, which must be extracted from real-time telephone event messages and then tracked and managed by the application software as the call progresses. The enhanced SDK software applies the appropriate call tracking logic, manages the call reference identifiers, and supplies the call information detail required by the call processing software and the telephone system. The standard application programming interfaces (APIs) for Intel NetMerge Call Processing Software require the application developer to maintain data items representing the association The enhanced SDK maintains this information internally and supplies it to the call processing software as required. Consider a typical Intel NetMerge Call Processing Software request sequence for establishing the second leg of a transferred call and then completing the ... This paper begins by examining design team interactions and requirements for a software-driven concurrent hardware and software design flow.http://www.vastsystems.com/documents/SoftwareDrivenEmbeddedSystemsDesign_v1.pdf. It is becoming more common for software content to be the collective re-sult of collaborative efforts involving semiconductor suppliers, software content partners, and original equipment manufacturers. As software content escalates the time required to develop, integrate, and test the system software threatens the viability of delivering products within market time windows. The simple objective of concurrent hardware and software design is to enable the parallel development of embedded system software and hardware with the goal of improving time to market and delivering highly optimized products with higher quality. With the growing importance of soft-ware the design flow must be Software Powered—meaning that the effect of the software must be considered in all stages of design. Software developers employ the VP as a surrogate for hardware allowing much earlier software development. Software developers receive revision requests from the system verification team when their target software fails to meet system requirements. Software developers may send revision requests to the architec - ture team when the architecture fails to meet their requirements for performance, power, and costs for a given software implementation. While these failures can expose architecture shortcomings, generally, architecture revision requests are left to the hardware or software engineering teams who request such changes if-and-only-if the failures can not be rectified in software or hard-ware implementation ... The Multiple Roles of Software Testers The test objectives that can be incorporated into the mission of software testers.http://www.softwarecertifications.org/cstebok/CSTECBOK2006.pdf. This would include the testing to determine whether requirements are met, testing effectiveness and efficiency, testing user needs versus software specifications and testing software attributes such as maintainability, ease of use and reliability. Competency of the Software Testers – management must provide the training necessary to assure that their software testers are competent in the processes and tools included in the test environment. Software testing is a project with almost all the same attributes as a software development project. 3. Project Relationships – software testers need to develop an effective working relationship with project management, software customers and users, as well as other stakeholders having invested interest in the success of the software project. Test planning assesses the business and technical risks of the software application, and then develops a plan to determine if the software minimizes those risks. a. Identifying Software Risks – knowledge of the most common risks associated with software development and the platform on which you are working. The objective of software development is to develop the software that meets the true needs of the user, not just the system specifications. This same process can be used by software testers when users are unavailable for test; when diverse users use the same software; and for beta testing software. 1. Acceptance testing is a formal testing process conducted under the direction of the software users to determine ... faster development, significantly reduced costs, and more reliable software.http://www.martinfowler.com/ieeeSoftware/componentChaos.pdf. In this view, the hard work of software development moves from building complete systems to designing and creating these individual components, but even this is easier given the boundaries on compo-nents. The difficulty in software development’s assembly phase involves identifying the appro-priate components to use rather than creating complex software. Clearly, the components used in software systems may not in-teract in arbitrary ways. functional requirement: A system or software requirement that specifies a function that a system/software system or system/software component must be capable of performing. These are software requirements that de-fine system behavior—that is, the fundamental process or transformation that the system’s software and hard-ware components perform on inputs to produce out-puts. performance requirement: A system or software requirement specifying a performance characteristic that a system/soft-ware system or system/software component must possess—for example, speed, accuracy, and frequency. external interface requirement: A system or software requirement that specifies a hardware, software, or database element with which a system/software system or system/software component must inter-face, or that sets forth constraints on formats, tim-ing, or other factors caused by such an interface. design constraint (requirements): A software requirement that impacts or constrains the design of a software sys-tem or software system component. Examples of de-sign constraints are physical requirements, perfor-mance requirements, ... Many web-based software systems contain a number of common types of components and functionality.. Calling application code based on HTTP posts, performing database transactions, rendering HTML responses, and putting all of the system’s functionality into a scaleable, extensible architecture are all common concerns in these applications. Because of the prevalence of web applications in today’s world, these problems are faced by many developers worldwide on a daily basis. These systems have been tried and tested many times and are well known for the robust solutions they can provide. Unfortunately, with such a robust architecture seems to come an inherently large amount of overhead in terms of configuration and setup. Many proponents of the framework will be quick to tout quotes saying that it can make developing web systems ten times faster than performing similar tasks with competing, more complex frameworks like J2EE. Rails was developed while its creators were building a real life system with it. While this may sound like a bad thing, it actually allows for a much easier time in creating the types of solutions that it is specifically designed for. This means less time spent writing configuration files and more time working on the idea of the product. These little things collectively work together to create a development experience which overall seems much more agile and less cumbersome than the process involved in working with other large and robust web development architectures. For several years, they had been using PHP for their applications and trying to build up a reusable framework. It was clear that ... Software is essential to the operation of the Nation’s critical infrastructure.http://www.us-cert.gov/reading_room/infosheet_SoftwareAssurance.pdf. Software vulnerabilities can jeopardize intellectual property, consumer trust, and business operations and services. In addition, a broad spectrum of critical applications and infrastructure, from process control systems to commercial application products, depends on secure, reliable software. The Software Engineering Institute estimates that 90 percent of reported security incidents result from exploits against defects in the design or code of software. Ensuring software integrity is key to protecting the infrastructure from threats and vulnerabilities and reducing overall risk to cyber attacks. To ensure system reliability, integrity, and safety, it is critical that provisions be included for built-in security of the enabling software. the Department of Homeland Security’s (DHS) Software The program provides support and guidance for significant new research on secure software engineering. This research is examining a range of development issues, from new methods that avoid basic programming errors, to enterprise systems that remain secure when portions of the system software are compromised. Through these efforts, DHS seeks to reduce software vulnerabilities, minimize exploitation, and address ways of improving the routine development and deployment of trustworthy software products. Together, these activities will enable more secure, reliable software that supports mission requirements across enterprises and the critical infrastructure. The key objective of the Software Assurance Program is to shift the security paradigm from patch ... Software for embedded systems is becoming ever more complex.http://www.appinf.com/download/C%2b%2bBetterDeviceSoftware.pdf. This requires a radical re-thinking in the embedded software development community, comparable to the Assembler-to-C transition years ago. While, at least to a certain degree, object-oriented principles can also be applied to C programming, a programming language with inherent support for object-oriented programming brings many advantages. C++ has many features that make writing reliable and robust code easier than in C. This paper introduces two ANSI C++ techniques that can be used to write more reliable and robust code for embedded systems. The paper is targeted at developers having a basic knowledge of C++, and who might consider moving to C++ for their next project. Object-oriented software development is a proven solution for taming software complexity. This is comparable to the fact that structured programming can somehow be done in Assembly language. However, doing structured programming in a high-level language like C is much more efficient. C++ has many features that make writing reliable and robust code easier than in C. C++ is thus slowly but steadily replacing C as the programming language of choice for embedded or device software development. While C++ (or at least some of its features) has often (falsely 1) been considered prohibitively resource intensive for embedded devices, especially with today's available powerful embedded hardware and mature compiler and build system technology, this is certainly no longer the case. Under certain circumstances the code generated by a state-of-the-art C++ compiler may even be more efficient than the code ... This is the fourth and final installment of a four-part series of articles that summarize our experience and discuss the key approaches that have enabled our customers to make substantial improvements in their software development economics.http://www.cognence.com/pdfs/ImprovingSoftwareDevelopmentEconomicsPartIV.pdf. In the second and third articles, I discussed the discriminating techniques that have succeeded for organizations that have achieved quantum leaps in software capability. In this final article, I discuss some of our key observations in collaborating first-hand with leading software development organizations and some of the patterns of success for transitioning project teams to these new techniques, methods, and processes. Improvements in the economics of software development have been not only difficult to achieve, but also difficult to measure and substantiate. In software textbooks, trade journals, and product literature, discussions of this topic are plagued by inconsistent jargon, inconsistent units of measure, disagreement among experts, and unending hyperbole. If we examine any one aspect of improving software economics, we end up with fairly narrow conclusions and a limited value observation. Similarly, if an organization focuses too much on improving only one aspect of its software development process, it will not realize any significant economic improvement, even though it may improve this one aspect spectacularly. In the software marketplace, the track record has been that three out of four projects don't succeed. In Rational's experience, the organizations that have truly achieved a quantum leap in improving their software economics are the ones that have demonstrated ... | |
