“Bob Charette declares that ‘every Lean Development is a team effort,’ and ‘success depends on active customer participation’” (Agile Software Development Ecosystems, p.120, Highsmith, J., Highsmith J. A., Eastlake, D., Niles, K.).
“Impediments can be logistic, such as lacking equipment or supplies, or organizational, such as slow approvals or inadequate user participation” (Agile Software Development Ecosystems, p.247, Highsmith, J., Highsmith J. A., Eastlake, D., Niles, K.).
“…once a detailed requirements specification has been completed, customers can view their participation as no longer needed…” (Agile Software Development Ecosystems, p.257, Highsmith, J., Highsmith J. A., Eastlake, D., Niles, K.).
“Success depends on active customer participation. Active participation is a collaborative, joint effort. Customer participation is more than just “buy-in”; active participation is essential to adapting to change and making real-time tradeoff decisions— from user interface design to feature alternatives” (Agile Software Development Ecosystems, p.68, Highsmith, J., Highsmith J. A., Eastlake, D., Niles, K.).

“Overstaffing a team can waste its members’ time by minimizing their participation and giving them too little to do” (Patterns for Effective Use Cases, p.32, Adolph, S., Bramble, P., Cockburn, A., Pols, A.).
James Shore
“Because the participation of the visionaries is so valuable, I take extra steps to include visionaries in any way I can” (The Art of Agile Development, p.204, Shore, James, Warden, S., Shore, Jim).
“Accordingly, the planning game requires the participation of both customers and programmers” (The Art of Agile Development, p.219, Shore, James, Warden, S., Shore, Jim).
