    Expert Ruby on Rails Developer, Team Lead, PM

    Thailand - Tests: 3

    70% of all software projects fail. Why is that happening? A few reasons: - Poor communication - Poor communication - Poor communication - Badly defined requirements - Wrong project's priorities - Sloppy development practices How do I address these issues: *Communication & Requirements clarification* - Monday to Friday daily status meetings at fixed time, suitable for all team members(customer is a team member). - Weekly iteration planning meetings. - Transparent and easy-to-use Project Management tools. *Project prioritization* - Complexity estimation - Short iterations & short feedback loop *Development practices* - Perfectly clean code - Test Driven Development (99% test coverage). - Obligatory code review & collective code ownership. - Domain Driven Design, Lean Architecture, GRASP, SOLID If this sounds good for you, let's get this done.
