SDev has been contracted by AeroDynamics to develop a mission critical software application, namely AeroViz, as part of one of their aircraft products which usually take at least three years to develop. SDev has a small development team with team members growing, but at the same time retention of some key members has been a challenge for SDev in the past two years. The AeoroDynamics company has very busy and tight scheduled tasks for their employees, who are geographically dispersed and are usually consulted by SDev during the product development life cycle. The appointed SDev project manager has decided to adopt a plan- driven approach for project planning, and accordingly the software development life cycle model. Discuss whether the SDev project manager has made an appropriate decision to undertake a plan-driven approach or not? Justify your answers and provide key recommendations for managing and developing the AeroViz application.
