best practices and principles in application development and maintenance

Software quality assurance is a broader term and the whole process spans the entire life cycle of the development of software, application or program. But we have to keep moving forward. Prepared using APQC’s Open Standards Benchmarking® data in IT Application Development and Maintenance, the articles in this collection highlight IT application development and maintenance key benchmarks for organizations across industries.The collection includes metrics related to cost effectiveness, cycle time, process efficiency, and staff productivity. DevOps is a set of principles and practices which help to improve communication and collaboration. Maintenance and enhancement of application software consume a major portion of the total life cycle cost of a system. and amicable relationship with the business users who know this information. Four Best Practices For IT Availability And Service Continuity Management ... Resiliency has to be a part of application development, infrastructure selection, and acceptance testing. Critical risks in outsourced IT projects: the intractable and the unforeseen. This Operations and Maintenance (O&M) Best Practices Guide was developed under the direction of the U.S. Department of Energy’s Federal Energy Management Program (FEMP). Maintenance project process consists of following phases as shown in the figure 1: Figure 1: Software Maintenance Life Cycle. (Requirement to Implementation) in your application Development? innovative strategies are sought. were achieved, of Programmer Productivity, John Wiley & Sons, New York. Tests don't need testing. Estimate the Job Based on Planner Expertise. The paper describes a method to effects of code inspection and structural testing on software quality. Therefore it will become increasingly necessary for Service Providers to develop offshore outsourcing capabilities. testing before being moved to Acceptance testing. approach is to reduce the time spent on early testing, yet increase the Maintenance of software projects is an important phase in software engineering. In part, this is the consequence of measurement difficulties. As we have learned from the first chapter, microservices are a lightweight style of implementing Service-Oriented Architecture (SOA). Facility Management: Three Best Practices Preventive maintenance, analytics, and a proactive infrastructure are key to an effective facilities management approach. banking, insurance, healthcare etc.). 1.

International Journal on IT/Business Alignment and Governance, Xavier Institute of Management, Bhubaneswar (XIMB), Characteristics of Application Software Maintenance, Contracts in Offshore Software Development: An Empirical Analysis. CMMI-DEV provides the latest best practices for product and service development, maintenance, and acquisition, including mechanisms to help organizations improve their processes and provides criteria for evaluating process capability and process maturity. However, when it comes to SaaS applications, maintenance is often solely up to developer. Provide FAQs and troubleshooting help online (self service). We further compare the evolutionary computation techniques using the Friedman ranking. were missed by inspection and vice versa. Table 2 shows the questionnaire that was used for collecting data. Application Development & Maintenance Benchmarking Association™ is dedicated to the analysis and improvement of business processes in application development and maintenance. We study the determinants of contract choice in offshore software development projects and examine how the choice of contract and other factors in the project affect project profits accruing to the software vendor. The nature of evolutionary computation techniques makes them better suited to the software engineering problems. To avoid potential problems, follow the best practices introduced in this guide. responsibility to improve accountability. The dynamics of enhancing or adapting a product to address evolving Change is a constant; therefore, the API should be a core strategic element in fast deployments, rapid changes, innovativeness, and experimentation. To reduce the cost of maintaining software projects, ... To find a solution to these problems, an approach has been developed to successfully address these issues and challenges. researchers to investigate the optimal mix of defect detection Project planning How would you rate your project against levels available in CMM or CMMi? Solutions, Prentice-Hall, Englewood Cliffs, NJ. This article discusses one viable approach ᾢ the use of automated programmer productivity tools. on time and on budget. To cover the latter, an extensive set of 104 references is provided.

It poses additional risks on both Service Recipients and Providers, which need to be carefully evaluated and assessed. 3. Hall, Inc., Englewood Cliffs, New Jersey. 4. The results of the analysis indicate that: (1) maintenance and enhancement do consume much of the total resources of systems and programming groups; (2) maintenance and enhancement tend to be viewed by management as at least somewhat more important than new application software development; (3) in maintenance and enhancement, problems of a management orientation tend to be more significant than those of a technical orientation; and (4) user demands for enhancements and extension constitute the most important management problem area. Responses were analyzed with the SPSS statistical package. Wesley Publishing, Reading, Massachusetts. Phase planning MuleSoft provides a widely used integration platform for connecting applications, data, and devices in the cloud and on-premises. Rough estimates of the total systems and programming resources consumed range as high as 75-80 percent in each category. little evidence to support the hypothesis that structural testing Key Issues with off-shored software maintenance projects. A number of API development best practices have been created in order to facilitate the development of the most valuable and consumable APIs. And at the heart of an efficient facilities operations department is a responsive, consistent maintenance structure. The right training and skill sets are critical to fulfill the technical gaps and … 4. Security Training & Skills. many approaches and solutions have been offered to address the limitations and often does not provide conclusive evidence. evolution during maintenance life cycle as well as helps in managing larger projects. The overall organization of project management is expressed as a process-based methodology, which can be tailored to a project’s specific needs. However, the area as been given little attention in the literature. Need to try to reduce the number of connections between different classes (aka coupling) Related classes should be in the same module/package/directory (aka cohesion) By following this principle, the application becomes more flexible, understandable and maintainable. studies are used to illustrate the key points. Classes or entities should be independent. software development project. Figure 2: Decision Making Matrix to offshore projects. detects different defects, that is, defects of a particular class, that Existing development processes have Each is unique in terms of accompanying documentation.The Waterfall approach is a linear method with distinct goals for each development phase. Pre-partnering lets clients and vendors develop a clear understanding of a project---including how well the other will handle its inevitable complexities. Their flagship product is Greycells - a highly powerful, technology agnostic, Over the past couple of years ABCsoft has made an important contribution to in creating, The researchers held number of face to face interviews with project managers and team. Do you use train the trainer concept? Planners are typically senior level technicians who … To analyze the problems in this area a questionnaire was developed and pretested. maintenance activities data processing activities are not a. practices that have helped in overcoming these issues. Project management also formalizes control mechanisms to help the project team share critical project information and coordinate with external stakeholders. Project completion. In order to compose quality code, developers need to test the software regularly. The project managers revise the plans, and schedules, as more information is available. In order to reduce the cost of maintaining software project, many such projects are being outsourced to low cost development countries like India, Philippines, Russia or China. which can be feasibly addressed in the current effort. Infosys Delivering "True Partnership" with Application Management Services. A defect prediction model is built by training a learner using the software metrics. All rights reserved.

They are designed to be consumed by specific audiences (e.g., mobile developers), they are well-documented, and they are versioned so users can have certain expectations of the API maintenance and lifecycle. satisfaction and repeat business from the same customer, and figure out the best place at a high level for the bug fi, chances of future rework, setting the correct expectation from the customer. Much goes on here that does not currently meet the eye. We are aware that a single experiment has many Many studies have been conducted in the past for predicting defective classes in the early phases of the software development. The best practices so identified such as training the trainer, process oriented systematic approach, developing a test strategy and involving end users during execution can be adopted in other organizations as well. Anypoint Platform, including CloudHub™ and Mule ESB™, is built on proven open-source software for fast and reliable on-premises and cloud integration without vendor lock-in. A fuzzy inference engine which embeds human expert knowledge expressed through natural language gives a superior capability to this approach. Test Automation. The consciousness for quality in projects and products has been. Control and reporting Through the exchange of data gathered in benchmarking surveys, members will be able to benefit from the experience of many companies. Using data collected on 93 offshore projects from a leading Indian software vendor, we provide evidence that specific vendor-, client-, and project-related characteristics such as requirement uncertainty, project team size, and resource shortage significantly explain contract choice in these projects. Quality management Join ResearchGate to find the people and research you need to help your work. The sources of risk in IT outsourcing were extracted based on industry survey and prior research. and can be emulated by other organizations carrying out maintenance activities. underlying problems, few offer methods which directly affect a team's However, there are many challenges associated with this maintenance phase, including technical and administrative aspects. This is particularly true in the development, The paper contributes a controlled experiment to characterize the Below are some of the best practices for 2020, that a quality assurance tester should apply: 1. It is a good idea to adopt some, if not all of those best practices, in order to create the best chance of API success in your organization: For more information about API development best practices, take a look at Undisturbed REST: A Guide to Designing the Perfect API. found a place for the change (if it is an existing page or screen), then the code related to, that page must be examined closely, by clicking on links and push buttons.

The survey covers the technology available in the various phases of the software life cycle—requirements engineering, design, coding, test, and maintenance—and in the overall area of software management and integrated technology-management approaches. API development best practices enable the full API lifecycle from design, build, test, through to deployment. In the not too distant future, unless this trend is arrested, or reversed, nearly all software resources may be required for maintenance. These findings suggest that version (sometimes also called as patch) of the software product is released. It was then submitted to 120 organizations. Well Architected can help you build and deploy faster, lower or mitigate risks, make informed decisions, and learn AWS best practices. The main challenges in software maintenance projects are: projects within the organization keeps the attrition low. Work management time, while maintaining ever increasing standards of quality, has caused testing using different coverage values as test criteria on a C-code The project m, Competency Assessment and Training Roadmap, Imple. Understanding and addressing risks are fundamental to partnership success in offshore IT outsourcing. Understanding Risk in IT Outsourcing: A Fuzzy Framework, The Systems Development Dilemma - A Programming Perspective, From Application Outsourcing to Infrastructure Management:: Extending the Offshore Outsourcing Service Portfolio, Emerald Journal of Emerging Markets Case Staudies, Design, implementation, and case study of a function level unit test environment, Studying the effects of code inspection and structural testing on software quality. With many software applications, consumers will have access to an entire internal IT team to help them with maintenance. MuleSoft's Anypoint Platform™ is a unified, single solution for iPaaS and full lifecycle API management. Hence, we Most importantly, APIs developed with these best practices are easy to build, productize, deploy and change. Configuration management statement of the relative issues, this paper defines what is meant by a The Lean model for software development is inspired by lean manufacturing practices and principles. Phase completion Please rate as 1 if. What is the domain in which your application is being developed? 2. modify the existing software product while preserving its integrity. enablement. maintainable software products. The web application development best practices discussed here can be applied to any Software-as-a-Service (SaaS) model. However, the evolutionary computation techniques have not yet been explored for predicting defective classes. In the meantime IS management must use other approaches, approaches that are available today, but that have been adopted very slowly. established software. Additionally, some ex ante vendor-, client-, and project-related characteristics known at the time of choosing the contract continue to significantly influence project profits after controlling for contract choice. The documentation types that the team produces and its scope depending on the software development approach that was chosen. complicated if it leads to litigation later on. renewed emphasis to be placed on software testing technology as Respondents totaled 69. Principles that govern the architecture process, affecting the development, maintenance, and use of the enterprise architecture ... referenced from credible sources along with associated best practices presently in use. service provider perspective, European Management Journal,27, Pp 418-428. This assessment could enable objective comparison of different projects and informed design of contracts and thus lead to partnership success in outsourcing. In this study we explore the predictive ability of the evolutionary computation and hybridized evolutionary computation techniques for defect prediction. A better way to manage application development and maintenance work 5 development clusters, leaving only Web/HTML programmers and a catch-all “other” bucket of devel- opers to stand alone. In addition, here are more resources about the comprehensive API design tools Anypoint Platform offers to comply with API development best practices. Project scheduling involves the creation. It is oriented primarily toward discussing the domain of applicability of techniques (where and when they work), rather than how they work in detail. The case of offshore software development simulated using the fuzzy framework showed that this method could capture imprecise perceptions about risk factors and quantify them effectively. defect coverage. of information. Furthermore, the experimental results indicate This is very much a good thing, but it requires you to keep some essential things in mind. API development best practices enable the full API lifecycle from design, build, test, through to deployment. of older, well This course provides an introduction to the development and support for Cloud-native applications, more specifically it delves into best practices of developing applications; migrating on premise applications to the cloud; the basic building blocks and properties expected from Cloud applications. ERP application projects are characterized by a high degree of uncertainty. These models can later be used to predict defective classes in a software system. One of the more robust areas of best practice developments is in the software industry. In this paper, we convey the results from case-based research into three firms. The APIs that have the most value and use for the enterprise are more like products than code. function level unit test environment and moves on to describe an actual It presents a classification of programmer productivity tools presently on the market and outlines the ways in which each class addresses productivity. classified using Orthogonal Defect Classification (ODC) and actual case The results are evaluated in terms of the values of accuracy. The results of this experiment show that inspection Include Risk Management with Quality assurance The goal of this Twenty subjects performed sequentially code inspection and structural Code must live on. Coding best practices are a set of informal rules that the software development community employ to help improve the quality of software. Our analysis suggests that contract choice significantly determines project profit. The scale and scope is extending from traditional application development activities to embrace infrastructure management. Managing the maintenance of ported, outsourced, and legacy software via orthogonal defect classifica... On the applicability of evolutionary computation for software defect prediction. However, there are many challenges associated during this maintenance phase, including technical and managerial. However, outsourced maintenance projects have their own issues and challenges such as poor domain knowledge, lack of understanding of application & technological knowledge and managerial issues such as lack of motivation, attrition. consider this experiment a starting point and encourage other product components and the risk associated with it. traditional class room training approach. Resource management Given the importance and value that APIs represent for numerous businesses, it’s important to consider API development best practices when designing and building APIs. significantly outperforms the defect detection effectiveness, From the perspective of maintenance, software systems that include there exist numerous resources on the technical development of a model, I have found fewer resources on the meta‐development of the model: that is, the ways and means of actually creating a model that are best suited for lasting success and easier maintenance. Some of the best practices your maintenance planners should use include: • Basing decisions on data • Prioritizing tasks with reliability in mind • Making sure materials are available • Getting out of the office • Striving for continuous improvement Many computer programs remain in use for long periods of time, so any rules need to facilitate both initial development and subsequent maintenance and enhancement by people other than the original authors.
