Final answer:
Time wastage in software development can occur due to delays in receiving work products and holding unnecessary weekly meetings, both of which disrupt the development cycle and impact project efficiency.
Step-by-step explanation:
Practices that waste time during software development include delays in receiving work products and having weekly meetings that are held regardless of whether they are needed. Delays in work products can cause significant interruptions in the development cycle, potentially pushing back deadlines and causing a domino effect that leads to project completion being delayed. On the other hand, unnecessary meetings can consume valuable time that could be better spent on actual development or problem-solving. Both of these practices can detract from the efficiency of the software development process.
