In order to design software, it is necessary to observe standard principles of designation, using templates and using modern methods. Over the decades, using development methods, XP and one of the XP methodologies of paired programming used to design software. These methods have been designed for purpose of enhancing quality of product and rapidresponse to need of market and customer and overcoming weaknesses of traditional methods based on long-term programming and waterfall method. Therefore, every programmer and developer can pass a series of processes for constructing computer software. The processes can be changed daily and efficient processes maynot be effective and useful; although they can be considered as process. The main objective of the present study is multi-factor analysis of pair programming based on PSP methodology. Practical and analytical methodand two PSP methods have been applied for investigations. Key words: software engineering, XP, pair programming, PSP methodology, multi-factor analysis INTRODUCTION In designing software, users play key role.

  • Enhancing Learnability of Pair Programming Practice When Introducing Novices

All sources, references and literature used or excerpted during elaboration of this work are properly cited and listed in complete reference to the due source. Advisor: Bruno Rossi, PhD. i Acknowledgement I would like to express my gratitude to my supervisor Bruno Rossi for leading me through the creation of my diploma thesis. I am grateful to him for stimulating discus- sions about the content of the thesis and supporting developing of my own ideas. I also want to appreciate his provided time, knowledge, valuable information and his patience and willingness. I express special thanks to my parents for their understanding, and my girlfriend for her support. ii Abstract The current thesis focuses on understanding the mechanisms that lead novice develop- ers to better learn the Pair Programming (PP) practice, one of the pillars of Agile Metho- dologies. The main aim is to provide theoretical-grounded suggestions that could help to improve the process by which novices are introduced to PP and start mastering it. To contextualize PP, we review the emergence of Agile development methodology com- pared to more heavy-weight methodologies and we evaluate the importance of PP as one of the key practices of Extreme Programing (XP). We then delve into empirical stu- dies that investigate the efficacy of PP in software development and into the identifica- tion of the state of the art in terms of the introduction of PP to novices.

Stauffer Final Approval and Acceptance by the College of Graduate Studies: Date: Dr. Jie Chen iii Abstract Software engineering is usually a team effort. Distributed software development needs real-time collaboration tools that help replicate the benefits of face-to-face meetings and support interaction among team members. Unfortunately, most of the tools that exist have limited capabilities, such as source code editing, and developers face collaboration and communication challenges in working with each other. Over the past decade software researchers have invented various development tools that integrate collaborative features. Unfortunately, most software developers still lack the right means and level of communication to coordinate their work and perform their tasks effectively, particularly in distributed settings.

THESIS TITLE: THE IMPORTANCE OF TEAM SKILLS FOR SOFTWARE DEVELOPMENT DEPARTMENT OF COMPUTER SCIENCE THE UNIVERSITY OF BRITISH COLUMBIA 2366 MAIN MALL VANCOUVER, BC, CANADA V6T 1Z4 Abstract Software does not just happen - it must be engineered systematically through the collaboration of individuals with necessary software development skills and appropriate tools. Similarly, effective software teams do not just happen - they too are built over time through the collaboration of individuals with appropriate team skills, tools and resources. This thesis outlines the need for superior software teams, reviews the literature on team performance and argues that a practical way to begin improving the effectiveness of software teams is in training software engineers in the skills necessary for effective teamwork.

  • Pair Programming: More Learning and Less Anxiety in a First Programming Course Susan F
    Pair Programming: More Learning and Less Anxiety in a First Programming Course Susan F. Freeman, Ph.D. *, Beverly K. Jaeger, Ph.D.*, Jennifer C. Broughamª *Northeastern University, ªMonash University Pair Programming is a recent development in education designed to enhance the student’s learning experience through teamwork. Specifically, it involves the students undertaking and completing some aspect of their programming work as a team of two. In engineering it is generally utilized for computer coding projects, such that partners work conjointly on the same design, algorithm, code, or assignment. For this study, this approach was used in a first programming course entitled “Engineering Problem Solving with Computation” by adapting the XP: eXtreme Programming method that is used in industry. The objective of this course is to teach first-year engineering students logic and problem solving skills through algorithmic programming. The programming language in the course of interest was C++. Pair programming was a voluntary element of the course and the students, under certain conditions, could opt in or out of it. The primary objective in offering this option was to reduce students' frustration when programming for the first time, as this often causes them to abandon attempts to understand the nuances of programming logic and syntax, and thereby the intended educational value of the course is lost. Pair-programming methodology requires that participants assume specified roles in a partnership. The course is administered and this option is selected with this understanding. Through various assessment tools, it was found that pair programming inspired confidence in the students, specifically in their ability to achieve the task at hand.

  • Software Engineering
    Chapter 15 Software Engineering So far we have talked in terms of one programmer designing an already speci- fied system. Software development in real life is seldom like this. Software is typically developed by programmers for customers who do not know precisely what they want. Programmers must understand the customer’s needs and then define exactly what the software should do before they can do any actual design. Software development is also typically done by teams of programmers, ranging from a small group of two to four people to a large team involving hundreds of people. Testing and deployment of software is also a major effort, often done by yet another group. Moreover, most of the effort put into a soft- ware system, especially a successful one, is spent fixing bugs and adding new features once the system has been “completed,” rather than on the system’s initial development. The study of software development, from a crude need on the part of a cus- tomer, through design and coding of a software system, and on through the ever-continuing process of fixing and improving the software, is called soft- ware engineering. This field has as its goal making software development sim- pler and the resultant software better. This chapter provides a brief overview of software engineering, describing the terminology and basic ideas developed by researchers and practitioners over the past thirty years. We first consider the problems that led to the field in the first place, proceed to describe the var- ious phases of software development, and finally discuss the ways in which these parts can be put together.
