Fundamental
The six elements of snapshot
What is...
Customers, Products and services, Major activities or work processes, Participants, Information, Technology
An ER diagram is?
What is...
a type of flowchart that illustrates how “entities” such as people, objects or concepts relate to each other within a system.
The relevance of making a prototype is...
What is...
Prototypes provide quick feedback: Customers are more likely to view and react to a prototype vs reading the SRS.
The prototype displays unanticipated aspects of the system's behavior. Thus, it produces not only answers but also new questions. This helps reach closure on the SRS.
An SRS based on a prototype tends to undergo less change during development, thus shortening development time.
Definition of the big bang approach
What is…
the implementation will be immediate and everyone who works in the system will be moved to the system at the same time.
Definition of an Enterprise system
What is...
Computer software that supports needs and solves problems of an entire organization
The elements of a use case diagram are...
What is...
IT system, actor, use case and relationship
Integrate business processes in manufacturing and production, finance and accounting, sales and marketing, and human resources into a single software system.
What is...
Firms use enterprise system, also known as enterprise resource planning (ERP) systems
The reason why system implementation fails according to Kim and Kankanhalli (Investigating user resistance to information systems implementation: A status quo bias perspective.)
What is..
User resistance to information systems implementation has been identified as a salient reason for the failure of new systems
The difference between waterfall and agile
What is...
Agile is an incremental and iterative approach;
Waterfall is a linear and sequential approach.
Agile separates a project into sprints; Waterfall divides a project into phases.
Agile helps complete many small projects; Waterfall helps complete one single project
In scrum, user stories are formulated as…
What is...
“As a … I want … so that …”
Match supply to demand
Reduce inventory levels
Speed up time to market
Use assets more effectively
Increase sales
What is...
Business Value of SCM systems
Three methods for change management?
What is..
ADKAR, Lewin's change management model and Kotter's 8-step change model.
Differences between Enterprise Software and Collaboration Software?
What is...
Enterprise software:
- Relatively rigid, focuses on larges business processes, handle enterprise core functions and customer in focus
Collaboration software:
- Relatively flexible, allow ad-hoc collaboration and set in the heart of the enterprise communication function
Difference between requirement specifications in plan based and agile processes.
What is…
Plan-based projects strive to early define requirements that are correct, unambiguous, complete, consistent, prioritized, verifiable, modifiable, and traceable.
Agile projects let requirements emerge over time through iterations and ongoing customer interaction.
The three types of cloud services?
What is...
SaaS (software as a service) Target group: end users.
PaaS (Platform as a service) Target group: Developers, External or internal
IaaS (Infrastructure as a service) Target group: infrastructure department or any one needs computing resources.
What are the four different perspectives on implementation?
What is...
Adoption, Learning, Affordance and Politics
3 pros and 3 cons of agile?
What is...
Pros:
More adaptive and applicable to almost any project in some way, as well as more welcoming to changing requirements late in the development
Frequent feedback (iterative development, frequent testing, focus on working software rather than documentation)
Self-organizing teams (high autonomy, focus on responding to change rather than following a plan)
People are more involved in the whole process and therefore more motivated
Cons:
Poor resource planning.
Limited documentation.
Fragmented output.
No finite end.
Difficult measurement.
Name three of Alter’s work system principles
Please the customer (customers and products)
Balance priorities of different customers (customers and products)
Match process flexibility (product and work practices)
Perform the work efficiently (work practices)
Encourage appropriate use of judgement (work practices)
Control variances (problems) at their source (work practices)
Monitor the quality of both inputs and outputs (work practices)
Boundaries between business process steps should facilitate control (work practices)
Match the work practices with the participants (work practices and participants)
Serve the participants (participants)
Align participant incentives with system goals (participants)
Provide information where it will affect action (technology and work practices)
Protect information from inappropriate use (information)
Use appropriate technology (technology and work practices)
Minimize effort consumed by technology (technology)
Take full advantage of infrastructure (infrastructure)
Minimize unnecessary conflict with the external environment (environment)
Support the firm's strategy (strategy)
Minimize unnecessary risks (system as a whole)
Maintain balance between work system elements (system as a whole)
Maintain the ability to adapt, change and grow (system as a whole
The three dimensions in the mandatory Walz text (Inside a Software Design Team: Knowledge Acquisition, Sharing, and Integration)
What is...
First dimension: acquiring, sharing, and integrating the necessary knowledge for the design task (getting up to speed).
Second dimension: integrating the knowledge into a shared understanding of the application and the design (creating the team memory)
Third dimension: The role of individuals in these activities.
The status quo bias theory aims at…
And the three main categories of the status quo theory are..
What is...
Status Quo Bias Theory aims at explaining people’s preference for maintaining their current status.
This is explained by three main categories:
- Rational decision making
- Cognitive misperceptions
- Psychological commitment
