  • 1. lines of code,

  • 2. duplication,

Understand Essential Concepts, Explain Them and Earn More
"If you want to make a promotion, your effectiveness depends on your ability to reach others through the spoken and written word" (P. Drucker). This cours will jumpstart your career by teaching you software quality through an analogy, which aids understanding no matter your background.

  • Anjo: "This is an excellent, cost-effective and very beginners-friendly course and I'm so glad to enrol in the class. Even though I have limited technical knowledge, I've learned so much with respect to software engineering basics. Now I feel that I am better able to challenge software engineers!"

So, after following this course you'll be like a general practitioner (GP). That person needs to know quite a bit about the human body. To assess the health of a human 'system' the GP uses key performance indicators (KPI's), such as: heartbeat and temperature. These KPI's enable the GP to quickly determine whether and what kind of follow up action is necessary. After following this course you'll understand the software design KPI's that can assess the health of a software system. You will be able to contribute to Code Reviews for Secure, Clean, and Scalable Code and more Effective Teams!

  • Teguh: "The the KPIs well explained"

Don't take my word for it

- What improves developer productivity at google? --> Code Quality (Cheng, et al., 2022). It reduces chance of writing legacy and increases elegant software design with best in class software development practices.
- A scientific study that surveyed 1,831 participants, primarily software engineers and architects, found that "Developers perceive management as unaware of technical debt issues, and they desire standard practices and tools to manage technical debt that do not currently exist." This finding will not be applicable to you; In 1.5 hours you'll understand how to combat technical debt. Source of the study: Ernst, et al. (2015).

  • Guan: "Very clear, and logical ideas, backup with solid examples. Definitely looking forward to the author's next training. Small price to pay, but BIG promotion coming up for me next year."

BONUS: Tons of additional reading material for Developers AND Managers. I've selected the BEST books for you.

Highly recommended for beginners and even experienced developers looking to enhance their software design practices

By Ealek mia on 8/6/2023

Whether you're a beginner or looking to refine your software design skills, this course is a fantastic resource that will undoubtedly elevate your understanding of software development and help you build more robust and maintainable code.

By Agboro Joseph on 11/16/2022

I thought it was going to be regular bluffs like I see in similar courses. This course is very informative and comprehensive.

By Guan Guan on 10/26/2022

Very clear, and logical ideas, backup with solid examples. Definitely looking forward to the author's next training. Small price to pay, but BIG promotion coming up for me next year.

By Richard Hill on 12/2/2021

The quiz answer as to measuring system size is completely wrong -- it makes me not really trust the course author(s). The time it takes a developer to add a line of code should be completely independent of the system size -- if it's properly architected. Which is the whole message of this course, no?

By Vladimir Kozlov on 2/21/2021

Basically all video materials can fit to 4-5 pages PDF document. The speech speed is too fast with distracting backgrounds and strange camera views. Lack of pauses and logical accents in sentences. Examples are too simplistic and not sufficient. It looks more like a sharing of personal experience in 1 hour, rather than attempt to teach others. I would not recommend this course even for juniors as they may be deluded that the software quality is too easy and simple.

By Romeo Persad on 1/22/2021

Very practical information delivered in a few short videos that are easy to consume. Strong point of Soerin is that he manages to make complex information easy understandable, thus makes this course highly recommendable for every product owner.

By Rudhra Adhin on 1/19/2021

Very practical information delivered in a few short videos that are easy to consume. Mandatory course for every product owner! Clear and concise explanation of key concepts. The course is also interactive with lots of quizzes starting in section 3. Audio and video is perfect, high quality and clearly professionally edited. All courses on Udemy should have the high quality standards of this course.

By Anjo on 1/13/2021

This is an excellent , cost-effective and very beginners-friendly course and I'm so glad to enroll in the class. Even though I have limited technical knowledge, I've learned so much with respect to software engineering basics. Now I feel that I am better able to challenge software engineers on software quality. I'm so grateful to have the instructor spending and sharing his knowledge. Again, thanks and this course is highly recommended!

By Vinod Sardjoe on 9/17/2020

Soerin Bipat is an incredible teacher! He makes the material easy to follow, and himself will answer any questions you have within a really short period of time (always less than a day!). I learned tons and I had a lot of fun going through it. I recommend this course to anyone interested in getting software right and learn the most important software quality concepts!
