Conclusion

Your job is to look at each testing sphere and, given the scope, goals, and objectives of your organization's automation effort, to decide what category(ies) of test tools (manual or automated) should be implemented to support that sphere. You will find that you have to make compromises and concessions and that an ideal test automation framework is just that: an idea. What you will finally implement is a mélange of tools and techniques that are appropriate for your needs.
