Requirements-based Estimating and Scheduling Best Practices
Steven Rakitin, Software Quality Consulting, Inc.

The increasing demand for complex software coupled with the inability of many organizations to write clear, concise requirements results in increased development costs, increased rework, and lower quality products.  All of which have a negative impact on your company's bottom line.  Since software project teams are often unable to accurately estimate and schedule the work they need to perform, management frequently imposes the delivery date.  With an end date mandated, project teams must "schedule backwards."  Schedules developed this way are always unrealistic since task duration is estimated based on time available rather than time required.  This interactive workshop presents the skills necessary to learn how to under-commit and over-deliver.  Steve will focus on the importance of writing good requirements and the specific skills needed to accomplish this.  He will discuss basic estimating and scheduling skills and review several best requirements-based practices including the Wideband Delphi Method and the Yellow Sticky Method.

  • Learn how to write better requirements
  • Understand ways to accurately estimate tasks based on those requirements
  • Explore the development of accurate schedules based on these estimates

Using Test Measurements to Influence Project and Organizational Behavior
Richard Bechtold, PhD, Abridge Technology

During this tutorial Richard will focus on practical methods for influencing project and organizational behavior using testing measurements and simple statistical and quantitative techniques.  He will show you how to develop this information from the perspective of particular individuals within the test organization and how it can then help them to positively impact systems and software projects.  The tutorial will begin with a discussion on the value of measurements and quantitative methods.  The fundamental principles of measurement and analysis will be presented, including the measurement and analysis lifecycle, attributes on measurements, data classification taxonomies, data packaging and display, prevention of misinterpretations, measurement-based testing, and maximization of influence.  The tutorial will also cover the application of traditional statistical and quantitative methods to the test environment including histograms, scatter diagrams, cause and effect diagrams, run charts, and control charts.  Richard will conclude with a discussion on sustaining a practical measurement focus and initiating ongoing data-driven improvement of test processes.

  • Improve your understanding of measurements and quantitative techniques and their application within the testing environment.
  • Understand methods for using facts and data to communicate with and influence others.
  • Gain insights into a variety of measurement-related challenges and opportunities in order to increase success in testing activities.

Test Design and Combinatorial Testing Explained
Peter Zimmerer, Siemens AG

Starting with a risk-based testing strategy, adequate test design is the key for effective and efficient testing. Yet, there are many different test design methods from which to choose.  Perhaps there are too many since, when we look into actual practice, we can see that there is limited usage of these test design methods.  In this tutorial, Peter presents a test design poster called "Test Design Methods on One Page."  With it he explains the big picture of test design methods by delivering a systematic, structured, and categorized overview.  Next, good test designs often require testing many different sets of valid and invalid input parameters, hardware/software environments, and system conditions.  This results in a combinatorial explosion of test cases.  The classic question for effective testing is always, "Given limited time and resources, which of the combinations should be tested?"  Peter will describe the underlying problems and challenges in test case design for combinatorial testing and explains solutions using different testing techniques. An overview of supporting tools is also given.  Successful experiences gained from real-world projects are discussed.  You will leave with a set of practical skills for developing successful testing in your organization.

  • Understand test design methods from a categorized big picture perspective.
  • Learn how to design test cases for combinatorial testing.
  • Explore the features, characteristics, and use of tools supporting combinatorial testing.

Test Case Development in a Quasi-Agile Development Environment
Timothy Korson, PhD, Qualsys Solutions

"Pure" Agile development uses story cards to scope and organize requirements.  Each story is described in a sentence or two with details filled in by verbal conversations.  Because there are no written requirements that contain enough information for independent test teams to create comprehensive test suites, testers often find themselves in a difficult position.  The Agile philosophy is that testers must create test cases directly from verbal conversations with clients.  In effect, the test cases become the detailed requirements and testers take on the role of system analysts.  Eliciting test requirements directly from stakeholders requires that testers learn a new set of skills and processes.  In addition to explaining how to effectively create system test cases from stories and stakeholders, this tutorial will examine the development of unit, component, increment, and regression tests as a part of a comprehensive testing process in an agile development environment. Test automation strategies and tools will be presented, and best current practices discussed.

  • Learn the skills necessary to develop test cases in an Agile environment
  • Discover Agile test automation strategies and tools
  • Understand the framework of a comprehensive testing process in an Agile world

About the instructor...
