Actually, I thought Wendall did a pretty good job of covering the implementation and verification parts of the exam topics in the ROUTE Cert Guide. For example, if you look at the Exam Preparation Tasks at the end of Ch. 2 EIGRP Overview and Neighbor Relationships, he goes into design, implementation plans, and verification plans. He does this for almost every topic on the exam.
Anyhow, the design, implementation, and verification process, is just taking what you already know and formalizing it. Its like, if you were going to implement EIGRP for an organization, what are your goals, what network resources do you have, what do you need, how would you do it, and how would you verify it was successful. It's a thought process.
Like I said, I thought Wendall did a pretty good job. I would suggest taking another look at the end of the chapters.
