Four Days Design Principles and Patterns Workshop

The Design Patterns Workshop offers a comprehensive introduction to design patterns, with a focus on patterns that have proven over the last decade to be most effective at addressing real-world software design problems.

The workshop helps people understand good object-oriented design through the medium of highly useful design patterns. Students are introduced to essential patterns via an amalgam of interactive discussions and hands-on exercises and quizzes.

The patterns taught in this course are drawn primarily, but not exclusively, from the classic catalog by Gamma, et al.: Design Patterns: The Elements of Reusable Object-Oriented Software Design. Students will gain a solid understanding of essential patterns as well as how to incorporate them into new or legacy code using modern refactoring and testing tools.



Basic Design Patterns
Advanced Design Patterns


Learning Outcome

At the end of this training the team will be able to:

  • Understand essential design patterns, and how to use them
  • Obtain a strong, fundamental understanding of Smalltalk style Object Orientated Development
  • Understand basic OO design principles and see how they apply to real world problems
  • Recognise code smells and understand how they violate the design principles
  • Obtain an excellent understanding of 10+ design principles and 30+ design patterns
  • Experience hands-on, refactoring to and away from patterns during the lab sessions
  • Gain a working vocabulary of design patterns
  • Understand how to evolve patterns into a design, rather than designing with them up-front

Strongly Recommended

1 or 2 Days of Mentoring via Pair Programming with Developers on your code base

  • To get your team kick-started with the learning from the workshop, we recommend, that our trainer spends a day or two, working with your team on your code base.
  • Each day will be reserved for 4 pair programming sessions. During these sessions, the workshop participants will take specific examples from their projects, where they are finding it difficult to apply any of the practices learned in the workshop. The trainer will then pair with an individual to show how to resolve those challenges.
  • At the end of the day, the 4 volunteers will summarize their learning by showing before and after code from their respective pairing session to the rest of the group.

Pre-Post Programming Assessment

The goal of these programming assessments is to identify real and quantifiable measures for the learning achieved through our workshop.

Objective

  • Get a quick understanding of your knowledge and skill level with respect to Designing & Programming
  • Establish a baseline against which the effectiveness of the workshop may be measured
  • Customize our workshop based on specific areas identified in this assessment

Pre-Assessment

  • Before the workshop, we'll send a problem description, your developers will spend max 4 hours and solve the problem and send us the code. We'll evaluate the code and send you detailed feedback about the code, including areas for improvement. We can send different types of problems (fresh development, cleaning up existing code and so on.)

Post-Assessment

  • 2 week after the workshop, we send another problem and evaluate the solution code. A comparison between the Pre and Post Assessment should be able to clearly quantify per-participant level improvement.

Testimonials

"Inversion of Software Development", that's what Naresh gave me through his 5 days workshop at Amazon. He is one of the best mentors I encountered in my career.

The way he tries to explain TDD and Design principles with practical approaches, always challenging the concepts which we used to think were industry standards. Learning through his workshop, now coding is like blogging, drop dead simple, and you don't look back.

I hope we had more dojos like Naresh mentoring people in Indian Software Industries to let them know what real clean software development is all about. To sum up he instilled the idea - "Perfection isn't the goal, it's the baseline." about software development in me.

- Rajat Talwar, Software Engineer II, Amazon

It's been 3 weeks since I had the opportunity to attend a 3-Day TDD workshop followed by a 3-Day Design Patterns workshop by Naresh Jain. Post the workshops; I was able to fully test drive a feature that is already in production.

I had many take-away from his workshops, but the most important ones were - 1. It gave me the confidence that with TDD you can come up with good designs, 2. Learnt refactoring techniques and IDE tricks, 3. Got a deeper understanding of design values, principles and patterns. 4. Identifying code smells (the codes that I was proud of, now all I see there is code smells :P). But thanks to Naresh I know how to make it right.

- Chandan Kumar, Software Development Engineer, Amazon

I recently met Naresh Jain during Test Driven Development(TDD) training at my current organisation. He is very knowledgeable and also very effective as a trainer. His enthusiasm and confidence is a game-changer when it comes to motivating the workshop participants.

I've really benefited from his training and by applying TDD in my day-to-day work . It was a great experience and I wish, I could get a chance to work with him on a real project.

- Lokesh Gaur, Technical Lead,Samsung Research

Rarely have I met a trainer who was truly hands-on. The depth of knowledge and on-field experience of Naresh Jain is truly inspiring. His proficiency in agile techniques and TDD is bleeding edge.

We have benefited immensely in barely three days of TDD training with him. We wish he was on our team here in EMC2.

- Vimal Kumar, Principal Software Engineer, EMC2

Recently I attended Naresh's workshop on Test Driven Development (TDD) at Amazon, Hyderabad. It was a great learning experience and an eye-opener in few cases.

He is very involved with the Agile community and has worked with a lot of industry experts. That's the best part of getting trained by him. He is up-to-date with the latest trends and his skills are very relevant.

Naresh's in-depth knowledge and great attitude, fueled by his passion for technology makes him a great techie to work with. I had a great experience and would highly recommend him for training/coaching or even just to have good discussions.

- Akshay Johri, Software Development Engineer, Amazon
