Cisco is already touching the SMB and consumer segment, esp. with its managed services. Public TelePresence at a low enough price would be extremely attractive to consumers in less developed areas. With Cisco's experience in using games to promote its products, offering game hosting as a managed service is not such a big leap.
Of course there are many ways to separate the market. But apple has already got several segments that I believe work. First is the Mac line, within this is The education market. This includes 3 segments. Instructors, Students, and Schools. Instructors will be more likely to spend more on a single product, and buy software relevant to their subjects, but these decisions will influence there students to do the same, but generally students will seek a "value" product, and will buy software based on requirements. School on the other hand will buy a large amount of Computers and software at once, which also effect instructor and student purchases. So selling to schools will raise the sales in both other categories, and selling to instructors will raise the sales for students. This is just the first segment. You also have corporate industries which are similar to Education. Now lets move to the iPhone Segment within this segment you have to ask, why do people buy iPhone. There is the High-Tech segment, meaning those who always want the newest and best. Then you have the Mid-Tech segment. These are those that don't feel it is logical to flip out phones each year, they wait for two years before buying a phone. Now lets move into iPad. Interestingly this segment can move from business, to leisure. The business segment seeks to have an iPad because it allows them to get work done faster and easier. The leisure market seeks to have an iPad because it brings them entertainment and helps them relax. Then lets go to iPod. The wonder of the iPod, the product that sent Apple on a crash course to stardom. I believe the greatest segment for the iPod would be parents wanting to get a gift for kids / something to keep kids entertained. because the iPhone acts as a iPod there is a spill of sales that goes to iPhone, although the iPod touch does offer an affordable alternatives to those who do not want an iPhone. Although the iPod Nano does capture the convenience segment. These are just the segments for the Main Products of apple.
You can group similar users and similar items by calculating the distance between like users and items. Jaccard distance is a common approach when building graphs of items x users relationships. For each user you have a vector of N items that they had the potential to buy. For each product you have a vector of M users that bought that product. You can calculate a euclidean distance matrix of user x user pairs and product x product pairs using these vectors. Calculating the distance between u1 and u2: f(u1, u2) = intersection(u1, u2) / (len(u1) + len(u2) - intersection(u1, u2)) same with products: f(p1, p2) = intersection(p1, p2) / (len(p1) + len(p2) - intersection(p1, p2)) You do this for each of the N^2 and M^2 pairs. Then you rank each row of the euclidean matrices for the product matrix and the users matrix. This will give you rows of rankings for each user; Example: "product p1's closest products p4, p600, p5, etc..." These rankings are according to purchase behavior. Similar to Amazon's "people who bought this also bought..." This is only working with the purchase graph. You could segment users by price of item bought. Someone who bought a Macbook retina probably have enough money to buy an another expensive laptop but kids of only paid $30 for headphones probably don't.
That is one way but also clustering algorithms can help in doing it in a more efficient ways
"name the 3 types matrices used to manage risk in a project using information taken from PMBOK (Project Management Book of Knowledge) "If you have 5 projects running concurrently, describe a single matrix that would easily show how each of those projects were doing"
For both of these questions, I told them if there was a single correct answer, I didn't know it...but I walked them through how I would handle each question.
Why is an Agile Project Manager interview based on the PMBOK? That's a really, really bad sign. :)
For the second question, I'd probably use either a cost/schedule variance chart... since you can't assume the same budget or schedule for any of the projects, variance against plan would likely be the best way to go.
All of my past work experience has been mainly multitasking, from working with children to working in a restaurant. I am sure that if I can handle high stress multitasking situations like those I will be able to handle a front desk.
I try to get a sense of the need for the topics by asking subject matter experts and other interested parties; then I prioritize based on whether this is a new topic, a revision, a requirement to address changed circumstances, or a "nice to have." Emergency topics take first priority; then topics that can be completed quickly; then topics that are needed, but which will require more time to investigate.
You would have to draw up an outline that included variables with respect to deadline and value. Once that was accomplished, you should develop an analysis of each item with respect to profit, qty available, vs realistic completion of the project deadline expectation. Say we have 100 widgets that are slow sellers, with a low margin and time consuming to write, and 1000 widgets with the same amount of work, yet are far more profitable, you would outline them in a multi-fold hierarchical format. Equal work and deadline, unequal values. If the next four items were also fast sellers with high quantities and significant profit margins, and took as much work as the 100 widgets, decisions would need to be made. Rush jobs are better served by making compromises. It's better to exclude weaker profit items, in order to ensure all high profit items are included and the quality of the finished product does not read as slap-dash, and that pesky deadline is met. Over-reaching is the hobgoblin of lost accounts.
