iscussion Question:The use of smart phones is growing rapidly. What could be the possible limitations of using a smart phone instead of a traditional laptop? Identify at least two limitations. Are these limitations surmountable?There is currently no standardization in the operating system (OS) used in a cell phone. What problems does this pose to the use of cell phones for serious m-commerce such as banking? Provide a possible solution along with a sound rationale to overcome the problems without the requirement of imposing a standard.Consider the case of mobile computing used to automate checkout at a retail store, where a mobile device identifies its owner and a device such as RFID on each of the products being purchased identifies the products and automatically bills the customer for the products in his/her cart. What issues can you foresee with technological limitations when two customers leave at the same time? What ethical issues must be addressed to prevent charging another customer for goods purchased by someone malicious? Justify whether these issues can be addressed, and if so, how?

How Will You Measure Your Life?This is by necessity an individual project. Two of the key learning objectives for this course are to 1) learn about individual behavior and 2) learn about interpersonal behavior. One subcomponent of interpersonal behavior is leadership. And yet one of the most difficult people to learn to lead is oneself; what I refer to as “that guy or girl that we see in the mirror every morning.”As leaders of organizations, we frequently participate in strategic planning wherein, we document the organization’s values, purpose, mission, and strategy. In this project, you will reflect upon and document your personal values. You will think about your purpose and propose a mission. You will develop a life and career strategy based on your own strengths and weaknesses. We will effectively answer for each of ourselves, the question that Harvard Professor Clayton Christensen asked of the HBS class of 2010, “How will you measure your life (Links to an external site.)?”The good news is that there are no wrong answers because only you can answer these questions for yourself. However, the bad news is that nobody can give you the answers either. Your grade on this project will be based on the level of thought that you put into it. This type of reflection can positively affect the trajectory of your career and your life. You will get out of it, only what you put into it.
