Usage Scenarios

Conclusion

1. gem install devise from my Ruby directory
2. add gem 'devise' at the end of apps\guestbook\Gemfile
3. rails generate devise:install from apps\guestbook to configure my app for Devise
4. rails generate devise User to generate User model to hold authentication details
   1. check devise_for :users added to apps\guestbook\config\Routes.rb and set root if you haven’t already
   2. optionally edit model apps\guestbook\app\models\user.rb (I left it as is)
   3. optionally edit db migration file in apps\guestbook\db\migrate\<datestamp>_devise_create_users.rb (I left it as is)
5. rails db:migrate to update the database
6. rails generate devise:views to generate basic views log user

class GuestbookEntriesController < ApplicationController

'Must be logged in to delete entry') }

1. Integrity - who wants to spend time with or follow people they don’t trust.
2. Passion - it takes passion to overcome all the potholes on the road to success. Passion is contagious and helps motivate people.
3. Curiosity - it is hard to improve without curiosity, those that don’t take the time to learn and rationalize their positions will be ineffective in communicating and motivating others.

1. Integrity - There is no trust without integrity. This is foundational value and personal attribute that I took for granted thus leaving it out of the EB hiring framework. I really wish I could leave it off but subsequent experience has reminded me both of its importance and that it is not something to be taken for granted in our industry (just look at recent cheating reports in Universities, amount of resume inflation, and some of the industry behind the scenes blogs). I am grateful for having joined a group in IBM out of college where there was very little drama and a real commitment to integrity and ethics beyond reproach. IBM’s employee guidelines, that had to be signed off annually by every employee, had integrity beyond reproach as the highest tenet specifically singling out sins of omission that can affect decisions which is all to common in our industry. This really set the standard for the rest of my professional career as I unexpectedly joined organizations with far more drama and questionable practices. From a leadership perspective, lack of trust adds friction and can destroy organizations from within. Lack of integrity significantly affects an individuals ability to lead. There are celebrated counter examples where vision, passion, and success have overcome significant integrity and ethics problems, but I think most of us would prefer to avoid the distraction. Aside from personal experience with a candidate, professional references, web search, and maybe a criminal background check, the most effective way for evaluating a candidates integrity may be resume validation (ask the candidate questions that they should be able to answer easily based on what is in their interview) . I came across a HBR blog entry by Ron Ashkenas just today on this subject: Why Integrity is Never Easy.

2. Passion - People perform better when they are doing something they are passionate about. Passion takes many forms but a couple of important ones are passion for mission and passion for craft. Passion is also very personal, and understanding an individual’s passion is important for knowing how to motivate them. Individuals that have a real passion for your company’s mission will be more flexible in finding opportunities to add value to your organization, will likely provide macro insight as they have empathy for the organization’s customers, and stick with the organization during the hard times that are sure to come. Passion for the craft, i.e. building great software, is indicative of craftsmanship and personal continuous improvement that will constantly serve to improve organizational capability. To evaluate mission passion, you can look at domain experience (if they are really passionate about something, they should have done something to indicate it) and behavioral interview questions such as “why do you want to work here?” and “what distinguishes you from other candidates for this position?”  and “what do you like or dislike about our product? how would you make it better?” Passion for the craft can also be judged by experience, i.e. what has that individual done to improve their own and the state of the craft? Conference, blog, professional association participation can all be key indicators.

3. Curiosity - There is little growth or innovation without curiosity. Curiosity is at the heart of agility, craftsmanship, and continuous improvement all important characteristics for individuals and organizations. There is a lot of discussion of late on the success of startups based on their ability to pivot which is just another way of describing agility. It takes curiosity to constantly challenge assumptions, reevaluate business models and the market to know when to pivot. Similarly, advances in software development and decision making is dependent on constantly understanding and challenging assumptions as well as keeping abreast of the field. You can evaluate a candidates curiosity by asking the candidate why they made the choices they did, and what they learned from them in success and failure. The curious will have reflected and tried to develop or apply a framework to those situations. For software developers in particular, I like to ask how they learned a particular framework and what underlying principles and assumptions went into their development. You are looking for people that went beyond learning just enough to do the job at hand but have the insight on where the framework fits. You can always ask candidates what they are interested in and how they have pursued learning more about them to tie together passion and curiosity.
