The main focus of the article is on improving the reliability of software products by addressing people-related issues faced by software engineers. The author emphasizes that most problems in software development stem from human factors rather than technology. Issues like lack of office space, unpaid overtime, and poor teamwork can demotivate software engineers, making it ineffective to introduce new tools or techniques.
