MIST TEST 2 questions and answers A+ content 4-step process that makes up ANALYTICS -asking meaningful question -acquiring relevant data -analyzing data quantitatively -presenting the results 3 major categories of skills required for data science -hacking skills -math and statistics knowledge -substantive expertise Social Network theory Social network analysis involves the mapping and measuring of relationships and flows between people, organizations, systems, and other connected knowledge entities. The NODES in the network are the individual people while the LINKS show relationships or flows between the nodes. 1st vs. 2nd order questions -1st order: "What should i do?" -2nd order: "How should i find out what i should do?" Organizational Impacts of muting HiPPOs ... Definition of a business process - sequence of tasks or activities that take a set of inputs and convert them into desired outputs -business processes are goal-directed -can be completed in a sequence or parellel Silo Effect workers complete their tasks in their functional silos without regard to the consequences for the other components of the process consequences of poor organizational coordination -delays -increased lead time -increased cycle times -excess inventory -"just in case" vs. "just in time" -lack of visibility across the process -Status "where is my order" -how is the process doing BPMN and basic notation -Event -Task/Activity -Flow/Arc -Gateway Event represents a thing that happens instantly (receiving an invoice) Task/Activity represents a unit of work that has a duration (activity to pay an invoice) Flow/Arc connects objects with each other and shows the order of elements in the process Gateway object that represents things that separate and/or recombine flows User Experience the overall experience of a person using a product such as a website or computer application, especially in terms of how easy or pleasing it is to use Krug's first law of availability when you look at a web page, it should be self-evident. obvious. self-explanatory Visual Precendence -how our eyes scan context -"Z" pattern in designs without much text -"F" pattern in designs with more text -make it obvious whats clickable -minimize noise step 1 UX design: do research on users do research on your users: who are they? where are they from? where can you find them? step 2 UX design: build user personas summarize your research from the first step into 2-3 discrete user personas -personas are fictional characters created to represent the different user types that might use a sight, brand, or product in a similar way step 3 UX design: create user stories -bring the whole team together to define goals for each user -try to map out the whole scenario for the user's experience on the site or app -build the sitemap and think about navigation step 4 UX design: start creating wireframes and interaction prototypes step 5 UX design: UI, Visual design, and delivery -UX refers to user experience design while UI stands for user interface design (and closer to graphic design) step 6 UX design: metrics analysis: validate your design! -use analytics tools to track how users use the product, how they interact, can they reach the goal we want them to, etc. -A UX researcher will test designs and analyze data from actual users and give recommendations to improve the function and design wireframes (where they fit in UX design process, what should be included, how are they used) -a visual guide that represents the skeletal framework of a website or application what should be included in wireframe -navigation -input components -key interface elements characteristics of a project -definite beginning and end date -produces a deliverable or outcome (unique product, service or result). creates value IT project failures, generally - barely one in three projects succeeds (more than half never deliver their intended business benefits, large projects have a 5-10x higher failure rate) - most IT project failures are combination of both execution and business failures delivering business value from IT projects -Hazard #1: ambiguity of purpose: poor communication between the business unit and the IT unit leads to building the wrong system -hazard #2: unnecessary complexity: as a project grows larger, so does the risk of failure -Hazard #3: Absence of an explicit choice of Trade-Offs: Non-IT managers should prioritize the projects requirements in order to remove unnecessary complexity
