IS Strategy and the exam

Should be able to

Explain basic concepts and frameworks

Write discussion essays

Similar to discussion questions after each chapter

Based on (shorter) case descriptions

Ability to relate concrete case to textbook concepts, trends, principles, frameworks

Write critical assessments of suggested answers to such questions

7


Available technology – what should be learnt?

Understanding different types of information systems and applications often found

Traditional IS applications

Types and purpose

Problems / challenges with these

Novel types of applications / packages

ERP, EAI, corporate portals

Data warehouses

Workflow, collaboration support software

B2B and B2C integration

More detailed insight: only ERP

E.g., functionality, architecture, configuration

8


Available technology and the exam

Should be able to Explain / distinguish between different types of

applications

Given a problem (case description), discuss what type(s) of application might fit

For ERP, Explain the purpose of ERP

Explain the basic functionality and architecture of package solutions (e.g., SAP R/3)

Explain how development method and requirements analysis will be different for ERP vs traditional custom-development projects

Discuss pros and cons of ERP, typical pitfalls and issues to consider when buying or adapting

Given a case description, discuss whether ERP is a good solution or not

9


IS development methods – what should be learnt?

Modelling: Languages:

Data Flow Diagrams + connection to ER diagrams

Process descriptions (e.g., decision tables)

UML activity diagrams

Understand Concepts and notation

When to use the languages, how to use them

Ability to make models

Ability to review models Various review techniques

Syntactic, semantic, and pragmatic quality

10


IS dev., cont.

Requirements elicitation & specification

Various elicitation techniques

Interview, workshop: how to do them

Others: what they are

Which are good in which situations?

Different levels of requirements:

Goal level, domain level, product level, design level Task & Support tables vs use cases

Which levels are appropriate for what project types?

Non-functional requirements

Importance and challenges of NF reqs

Taxonomies (different types of NF reqs)

Security requirements

Interoperability requirements

11


IS development and the exam, possible Q’s

Make models / requirements From natural language case description

Translate from one representation to another

Evaluate a model or some textual requirements Wrt syntactic / semantic / pragmatic quality

And guidelines for the particular format

Given a NL case description

Suggest use of reqs elicitation techniques Given a project context

Or evaluate a given suggestion

Or evaluate an interview / workshop performance given transcript of a dialogue

12


What can this knowledge be used for?

Future work The course covers basics for IS consultants But need to learn more

On the job, or from future courses

Future courses More about IS development methodology

TDT4250 Modelling of IS TDT4290 Customer-driven project TDT4235 Software quality and process improvement

More about available technology TDT4245 Collaboration technology TDT4215 Document management and text mining TDT4210 Healthcare informatics

More about strategy Ind-econ. courses?
