Feasibility

Feasibility

Incorporates four dimensions: cost, schedule, technical and organizational

Pilot conversion

The type of system conversion where small groups of end users are identified to start using the new system and and additional groups are added over time.

Parallel conversion

In this type of installation (conversion), the new system runs alongside the old one until it has been tested and is fully operational.

Software (programs), hardware, people, data, procedures

Components of an Information System

Malware

A program or file that is harmful to a computer user- includes computer viruses and spyware.

Spacial data

=geographic feature + table

GIS

Analyzes and displays data using digitized maps to enhance planning and decision making.

Predictive analytics

The analytics method strives for insight and foresight, using techniques such as forecasting, among others. An example may be to determine which of the employee is most likely to leave.

Networked systems

The type of international information systems structure where the systems development and operations occur in a coordinated and integrated way across all units worldwide.

Expert systems

A system that captures the knowledge and expertise of an expert in a domain, in the form of facts and rules, to aid others in making decisions in the subject domain.

Data mart

Used within a data warehouse for specific functional areas of the organization like marketing or finance.

Human error and mistakes

Malicious human activity

Natural events and disasters

Sources of security threats

Management information systems

These systems are designed to summarize and report on organization operations in order to help the organization achieve its goals and objectives.

Create planned independent requirements

In SAP (the ERPsim), this is what you change to deploy a strategy of only selling two of you six products.

Biometrics

In IT this usually refers to technologies for measuring and analyzing human characteristics especially for identification purposes.

Difficulty in determining requirements

Changed in requirements

Difficulties involving scheduling and budgeting

Changing technology

Diseconomies of scale

Challenges of system development

Raster data

An array of cells, each displayed with color, showing elevations. Thereby measuring every inch on Earth.

Plunge conversion

Among the approached of System conversions, this is the one that should not be used unless there is a disaster that warrents it.

Vector data

Also known as a feature class. Helps to see geographic features and can combine features by adding a map layer.

Neural system

Artificial intelligent systems function the way the human brain does with networks that recognize patterns in data.

Systems definition (feasibility)

Requirements analysis

Design

Implementation

Maintenance and review

FINAL JEOPARDY: Name the phases of a systems development life cycle

Process Mining

Provides insight into how processes are actually executed through visualization of digital footprints; Helps identify process improvement potential, eliminate waste and rework; Used to track process performance.

Prototype

An experimental version (or mock-up) of part of all of a new system for demonstration and evaluation purposes.

Computer forensics

The scientific collection, examination, authentication, preservation, and analysis of data to help on or retrieved from computer storage media in such a way that the information can be used as evidence in a court of law.

Data mining

The application of statistical techniques to find hidden patterns and relationships in large data bases.

Empathize, define, ideate, prototype, test

Design thinking methodology

Agile organization

The type of organization that can quickly adapt to changes in the market, industry, product, law, or another significant external factor.

Outsourcing

the term used to represent when a company turns over a significant portion of its information systems function to an external entity.

Providers, users, communities SMIS roles

SMIS roles

Clearly defined organizational goals; Clearly defined systems objectives; Support of top-level management; Involvement of users at all stages; a simple straightforward design; training for all; project management skills.

What are success factors in systems development?

Identify and describe facts

Define conflict or dilemma, the values involved

Identify stakeholders

Identify the options

Identify the consequences

(Consider rights-right to know, right to privacy, right to property)

(Consider personal duties-morals)

(Consider professional responsibility)What would you do to access ethical implications

What would you do to access ethical implications

MIS Audit

An evaluation of all related information systems in an organization is used to identify controls that govern individual information systems and assess their effectiveness in the organization.

Intangible benefits

Improves customer satisfaction, better corporate image, improvoed decision making, increased job satisfaction, improved resource control, improved asset utilization... these are just some examples.

Benefits of business intelligence

reduces action time to nearly real time,

Business Intelligence Systems

Which of the following does this best describe - Information systems that process operational and other data to identify patterns, relationships, and trends for use by business professionals.

model base statistical: TPS, MIS, external data, DBMS, database \n Executive information system: for upper level, to make for higher level decisions

Components of DSS

1. acquire data \n 2. perform analysis \n 3. publish results

3 primary activities in the BI process

raw data

\n usually unsuitable for sophisticated reporting or data mining

true

A Pivot table is a method to slice and dice data - is this statement true or false?

Knowledge management systems

Which of the following does this best describe - Creates value from intellectual capital and sharing that knowledge with those who need that capital.

true

If a student wanted to know what courses to take next semester, an expert system would be more appropriate to use than a database system.

False

If a company wants to know how many customers have outstanding balances, an expert system would be more appropriate to use than a database to answer this question.

Intelligent Agent

A software program that assists you, or acts on your behalf, in performing repetitive, computer-related tasks.

DSS

anything that helps make decisions, organized collection of people procedures, softwares, databases, & device used to support problem specific

BigData

a collection of large, complex data sets, including structured and unstructured data, which cannot be analyzed using traditional database methods and tools
