The Software Process Improvement SPI Reward or Risk Mohamed Sami



It is written to enable scientists, teachers, practitioners, and students to define the basic terminology of software measurement and to contribute to theory building. Contrary to popular opinion, you can build extraordinarily high-quality software—and this book shows you exactly how the world’s best development organizations do it. To survive in today’s turbulent eBusiness world, software project teams must exhibit adaptability, speed, and collaboration. This book targets software teams where competition creates extreme pressure on the delivery process. For more than a decade, Steve McConnell, one of the premier authors and voices in the software community, has helped change the way developers write code—and produce better software. Now his classic book, CODE COMPLETE, has been fully updated and revised with best practices in the art and science of constructing software.

  • Learn how to transform XP theory into concrete Java® development techniques!
  • The framework contains the joint activities of both external and internal parties.
  • It presents extremely simple, but overwhelmingly powerful metrics, models, and methods for designing professional business cases and provides hard-hitting economic justification.
  • Correctly called a primer, it depicts and discusses multiple areas that need to be understood by Information Technology specialists and managers.
  • Chapter 2 presents the SPI Initiation framework in detail with activities related to each of the steps.

To automate a software estimation process using SLIM applications, you need to decide the types of estimates needed, whether you plan to gather completed project data, and whether desktop or web-based tools are best. A Rough Order of Magnitude Estimate Quick Ref Guide was created to show specific software tool screens and related data used in each step. An estimation process management checklist was also created to get feedback from practitioners and assess the thoroughness of activities performed. With your process improvement goals and plans in hand, the next step is to define and document the processes.

Set Goals

The Systems Engineering Capability Maturity Model (SE-CMM) concerns the description of the essential elements in an organisation’s systems engineering process that is required to ensure good systems engineering. SE-CMM provides a reference for comparing actual systems engineering practices against these essential elements. SE-CMM allows an organisation to select a specific process area and improve relative to it. By use of capability levels it is possible to characterize improvements that are relative to an individual process area. According to the SE-CMM model the quality of a product is mainly based on the process and technology used in the development of the product . Also the capability of the people involved in the work is significant to contribute to a high quality product.

It ensures the start-up of SPI and, for the present, all of the companies are continuing their SPI efforts. A not-for-profit organization, IEEE is the world’s largest technical what is software process improvement professional organization dedicated to advancing technology for the benefit of humanity. This book is a basic introduction to measurement and the validation and use of metrics.

Why Experienced Programmers Fail Coding Interviews

It is a must for anyone who plans to seriously introduce or experiment with the cleanroom ideas. This book gives the methods and theories needed to set up checks and balances for a software system. Due to the tremendous amount of code, complex software systems need to be carefully monitored to ensure they run efficiently when they are completed. Software Testing offers an up-to-date synthesis of information in the field of software testing. It is the only text to bring together the two fundamental approaches–functional and structural–with numerous practical examples and exercises.

Step 2 – Assess Processes The selected processes are assessed in detail using SPICE Part 5 compatible method. SPICE assessments are carried out using the assessment forms developed by Mr. Risto Nevalainen of STTF Oy and distributed by the Finnish Software Measurement Association . Assessors can be either external or internal (self-assessment) to the company. Continuous SPI steps in SPICE The flexible structure of SPICE makes it adaptable to even the smaller organisations – the improvement activities can be planned according to organisation’s priorities and resources.

Best Practices for Software Process Customization and Improvement

In order for the improvements to have an impact and function appropriately, it’s important to communicate changes to the team members involved. VSM helps teams see the big picture of your processes and pinpoint everything that can be improved. Create a personalized customer onboarding journey to eliminate redundant or irrelevant information.

Process improvement identifies process parts and the functional talents that could be groomed further – or filtered out – to enhance process quality. Positive Splitting the user story into tasks and splitting the tasks between people went well and everyone had opportunity to participate. We had communication with the team building the tractor to decide the size of the garage (however it was not enough and we didn’t notice them changing the size). Negative Went in blind, no clear idea how large anything was supposed to be. Lead to wrong size of tractor supplied by the other group and a way too large garage in reply.

Books Guide

Developed from an award-winning doctoral thesis at Carnegie Mellon University, this is a lucid, captivating analysis of organizational performance measurement. Textbooks tell us how to define metrics, but there is little guidance about exactly how to start and what has proven most effective in actual use. This book helps bridge that gap by bringing together important and practical papers on applying software metrics. Each chapter addresses a significant question whose answer is essential to building an effective measurement program. “Musa…is considered the guru of software reliability engineering.” – Michael R. Lyn, Ph.D., Technical Staff, AT&T Laboratories. Spotlighting the practical steps that you need to apply Software Reliability Engineering to software development and testing, this first-of-its-kind guide puts the efficiency-enhancing benefits of SRE within easy reach.

This part is initiated if there is a need to determine or improve process capability. For software organizations to assess their ability to implement a new software project. ISO/IEC provides a suite of standards to undertake such an assessment in a systematic manner. Not only the engagement but their involvement to be a part of that change and understand why it is important and how they will benefit from that. Most of the small companies do not have metrics to measure and compare their progress or improvement which make it sometimes impossible to identify measure the improvements of the SPI.

Standardization and Process consistency

A simple checklist can suffice for some process artifacts, such as small project requirements documents and project plans. Software process improvement initiatives must be planned and managed like a project. We recommend creating a small group with representatives from each affected area. The groups involved will be driven by the size of your organization and the way it is structured. Larger organizations tend to have more formal policies and procedures and several groups that must coordinate. Smaller organizations, of course, have fewer resources and often do not need as much structure.

A fundamental PSP principle is that everyone is different and that a method that is effective for one engineer may not be suitable for another. The PSP thus helps engineers to measure and track their own work so they can find the methods that are best for them. The organization sets quantitative quality goals for both software products and processes.

Systems Engineering Capability Maturity Model(SE-CMM)[edit | edit source]

Bringing you today’s best agile ideas and thought-leaders with how-to advice on the latest agile development & methodology practices. Heavy emphasis is on estimating–including an in-depth explanation of the COCOMO model. Even though this book was published almost ten years ago, it is still one of the most quoted books on the subject of software measurement. In this short but informative book on measuring software quality, the authors have shown not only what to measure , but have given some useful insight on how to use the measurements once collected. This comprehensive book incorporates the perspective of the IEEE standards (Hollocker chaired the effort that produced the ANSI/lEEE Standard for Software Reviews and Audits). The book has fresh material with good coverage of software audits and an emphasis on the use of audits for what Hollocker refers to as a “controlled process evolution.” The human side of reviews is not emphasized.
