1. Two companies that have been using crowdsourcing as an alternative to traditional systems development approaches are Threadless, a t-shirt company that allows users to submit designs and vote on their favorites for production, and Waze, a GPS navigation app that relies on user-generated data for real-time traffic information.

2. Two advantages of using crowdsourcing for developing a system or application include a wider pool of talent and ideas, as crowdsourcing allows for contributions from individuals with diverse backgrounds and perspectives. Additionally, crowdsourcing can lead to faster development timelines as tasks are distributed among a large group of people.

3. Two disadvantages of using crowdsourcing for developing a system or application are potential quality control issues, as the contributions may vary in terms of accuracy and reliability. Additionally, managing a large number of contributors can be challenging and time-consuming for the project manager.
