What is a data-driven culture? - Answers A data-driven culture uses data-driven decision
making
Examples of Google using data and analytics? - Answers At Google. decisions are based on
data, analytics and scientific experimentation.
Tried to answer the question of: Do managers matter?Determine the data to use (see what's
available and what might be needed) • Performance reviews (top-down) and employee surveys
(bottom-up) of managers • Looking for variability: Top and bottom quartiles • Analyze the data
using statistical methods
The abundance of data, and its implications and the potential benefits from analytics for
businesses? - Answers Big Data - The sheer volume of data
• Increased efficiency • Improved operations • Enhanced customer retention
Purpose and usefulness of Tableau and data visualization in general? - Answers Data
visualization is not a personal preference, to be done "just in case some people are more
visual." It is a necessity! • The previous slide is a classic example of how some insights can only
be found through visualization. Remember the picture superiority effect: pictures are retained
at much higher rates than words.A good visualization reduces the time to insight.
Value creation with data analytics (think exchange transactions and uncertainties)? - Answers
NO pie charts! Yes to scatterplots for exploring relationships. Yes to treemaps for relative
proportions. Orient data so people can read it (better to have a horizontal bar chart than a
vertical bar chart). Filled maps with only one measure, dash boarding
what is blockchain technology? - Answers A blockchain is a distributed ledger of transactions
, Blockchains lineage (where it came from/ first used)? - Answers A block consists of multiple
timestamped transactions • Multiple blocks are joined together in a chain • Nodes are
connected devices that have a copy of the entire blockchain • The nodes are periodically
synchronized to ensure consensus
What are the main parts of blockchain technology? - Answers 1. Users initiate transactions
using their Digital Signatures. 2. Users Broadcast transactions to Nodes. 3. One or more Nodes
begin validating each transaction. 4.Nodes aggregate validated transactions into Blocks. 5.
Nodes broadcast blocks to each other. 6. Consensus protocol used. 7. Block reflecting "true
state" is chained to prior Block.
Implications of blockchain buyers, sellers, and the middleman? - Answers The blockchain has
the potential to reinvent any transaction that now requires going through a middleman,
including finance, banking, contacts, and retail.
Blockchain applications - Answers • Cryptocurrencies, such as Bitcoin, Ethereum, Litecoin,
etc. • Digital identity • Any application where a secure, immutable record must be shared
between multiple parties • ensuring product authenticity • recording real estate transactions •
secure medical records
Various uses of blockchain technology discussed in the prep materials? - Answers finance
(bitcoin), banking, contracts (law), retail, voting, music and other arts, trusted concert tickets,
protect sensitive info,
How secure is blockchain? - Answers Blockchain is designed to store information in a way
that makes it virtually impossible to add, remove or change data without being detected by
other users.
Blockchain security (Is it unbreakable?) - Answers Blockchain is protected by business-grade
cryptography, but no technology is 100% secure. And when large sums of money are involved,
hackers will try to follow. So security concerns could also slow blockchain adoption. 51% rule
, Value creation with data analytics (think exchange transactions and uncertainties)? - Answers
• Informational uncertainty (IU) - no perfect information (bounded rationality) • Relational
uncertainty (RelU) - opportunistic behaviors (opportunism) • Resource uncertainty (ResU) - no
unlimited resources (asset specificity)

System Development Life Cycle (SDLC) - Answers The overall process for developing
information systems from planning and analysis through implementation and maintenance
SDLC Stages - Answers Systems planning and selection
Systems analysis
Systems design
Systems implementation and operation
What is the systems development methodology that focuses in iterative stages of defining,
building, and releasing features of a system - Answers Agile
