Benefits of Collaboration to Develop Safe and Secure Software

Considering various points of view

• Different team members can observe different insights into user behaviour, security threats, and system requirements
• Helps to reduce cognitive biases that could cause oversights
• Can anticipate a wider range of potential threats and challenges

Delegating tasks based on expertise

Efficiency and quality

• Team can work more efficiently and productively
• Security experts can handle threat modelling while developers focus on secure coding practices
• Each area of the software is developed by those with the most relevant skills, meaning the code is higher quality
• Helps to reduce redundancy and helps issues be addressed promptly

Accountability

• Promotes accountability, as each member has a specific role and responsibility
• Better progress tracking, issues, and resolutions

Quality of the solution

• Improved and higher security standards
• Better quality code from peer reviews, as security flaws are seen and fixed early in the development process
• More thorough testing and validation
• Continuous feedback for improvement
• More comprehensive documentation, which makes future security maintenance easier and helps new members understand security considerations in the codebase
