(05) An empirical investigation of the factors affecting data warehousing success.

Question 1

What does the paper focus on?

Answer 1

This paper focuses on the implementation of data warehousing projects. These projects have unique characteristics that may impact the importance of factors that apply to it.

Question 1

What do the writers argue why the literature lacks the theory on data warehousing?

Answer 1

The researches argue that there is a need to better understand data warehousing to ensure the success of these promising IT undertakings. They state that a data warehouse (an IT infrastructure project) is arguably different from a decision support application and that the literature lacks the theory that supports the success of these infrastructure projects.

Question 2

Three dimensions of system success were selected from the literature as being most appropriate for this study:

Answer 2

Data quality, system quality, and perceived net benefits. These three dimensions relate to one another: higher levels of data and system quality are associated with higher levels of net benefits.

Question 3

Data quality consists of

Answer 3

Data quality consists of:
(1) accuracy,
(2) completeness and
(3) consistency of the data in the warehouse.

Question 4

System quality is measured by:

Answer 4

System quality is measured by:
(1) system flexibility,
(2) integration,
(3) response time and
(4) reliability

Question 5

A system displaying high data and system quality can lead to net benefits for various stakeholders:

Answer 5

It can
- change processes,
- improve decision making
- and reduce decision making times.

Question 6

Organizational implementation success

Answer 6

This construct was measured using three question that captured
the extent that political resistance was dealt with effectively, change was managed, and support existed from people throughout the organization.

Implementation factors found to be of statistical influence on organizational implementation success:

1 . Management support
2. champion
3. resources
4. user participation

Question 7

Project implementation success

Answer 7

Questions that were about the project being completed on time, on budget, while delivering the right requirements. Associated with a champion, resources, user participation and team skills.

Implementation factors found to be of statistical influence on Project implementation success:

1. Resources
2. User participation
3. Team skills
4. Champion

Question 8

Technical implementation success

Answer 8

Defined as the ability to overcome factors as poor team skills, (bad) source systems, inadequate tools. Questions were asked about the technical problems that arose and technical constraints that occurred during implementation.

Implementation factors found to be of statistical influence on Technical implementation success:

1. Development technology

Question 9

Implementation success dimensions which were of statistical influence on system quality:

Answer 9

1. Organizational implementation success
2. Project implementation success

Question 10

Implementation success dimensions which were of statistical influence on data quality

Answer 10

None
