Best Practices for Writing Clean Code
This ninety-minute free webinar (with an optional thirty minutes at the end for Q&A) will help you quantify software qualities and understand the meaning of CLEAN code. Quality in delivered software is intangible and very different from quality in physical goods. Some external attributes of quality software—free from defects and easy to maintain—reflect the code’s internal qualities. When classes and methods are cohesive, non-redundant, well-encapsulated, assertive, and explicitly coupled, they are less prone to mistakes and far easier to debug, test, and maintain. David Bernstein asserts that paying attention to code quality helps us focus on the key principles, patterns, and practices used by expert developers. If you ignore critical code quality attributes, iterative development practices can quickly degrade code into a maintenance nightmare. Join me and deeply dive into the code qualities that make software more maintainable and less bug friendly. Create software that provides value now and is easy to change and extend so it can continue delivering value far into the future.
Benefits
Attending this webinar will show you how to create higher-quality software that will enable you to:
- Employ techniques that reduce defects.
- Quickly implement effective design alternatives.
- Collaborate more smoothly with other team members.
- See how testability directly reflects software quality.
- Establish standards and practices for building software.
- Avoid upfront overdesign and build just in time.
- Support an iterative process without excessive rework.
- Support collaborative code ownership and embrace a common aesthetic.
Who Should Attend
This training is for all team members and will benefit architects; designers and developers; development and product managers; software engineers/programmers; testers and QA engineers; and technical analysts, leads, and writers. Familiarity with basic Object-Oriented (OO) concepts and terminology is recommended.

- Testable—Code Must Be Testable; Testability Guiding Design; Pathologies of Poor Testability.
- Explicit—What are Explicit Relationships? Good Coupling and Bad Coupling; Kinds of Coupling; Coupling Example; Pathologies of Bad Coupling.
- Conclusion—The Six Code Qualities; CREATE Quality Software; Code Qualities Guide Us; Thank You!
Your Instructor, David Bernstein
My continuing passion for software design and construction has led me to train more than 10,000 developers since 1990 for clients including Microsoft, IBM, Yahoo, Boeing, AT&T, Sprint, Medtronic, SunGard, State Farm, MetLife, and Weyerhaeuser. As a longtime IBM consultant, I trained software engineers around the globe, giving them the skills to write the next generation of applications and operating system software while earning one of the highest satisfaction ratings in the history of IBM education. Since 2006, I’ve devoted my consulting practice to providing organizations with training and coaching for software developers and teams transitioning to Agile and Scrum.
