1. Complexity - Some software development methodologies may require learning and applying a large number of complex techniques and tools. This can be overwhelming, especially for newbies. This complexity can hinder a development team's progress, making the development process slow and inefficient.

2. Restrictive - Certain software development methodologies can overly constrain the development process and developer freedom. This can lead to a creative block, limiting the team's flexibility and adaptability.

3. Long development cycle - Some software development methodologies emphasize continuous iteration and testing, which may lead to a very long development cycle, thereby extending delivery time and increasing costs.

4. Interpersonal relationships - Software development methodology also requires effective communication and collaboration among development team members. If there is poor communication or poor collaboration, this can lead to project failure or the production of low-quality software.
