Testing and Installation Approaches, Exams of Business Statistics
Different approaches to software testing and installation. It explains the advantages and disadvantages of white box and gray box testing, and describes four approaches to software installation: direct, parallel, single-location, and phased. The single-location approach involves changing systems in strategic sites progressively, while the phased approach consists of installing parts of the system at a time. The document also highlights the need for extra attention from the IS department during the installation process.

Introduction
Black Box testing Approach A tester attempts to find errors such as Interface Errors Missing functions Performance Errors
White Box
testing
Approach
Advantages (^) Early Stage Testing (^) A more thorough testing Disadvantages (^) The tests are complex and require skilled resources (^) The tools for the implementation or platform may not be available
Software Installation Approaches
There are four approaches for software installation. These approaches
are classified in terms of time, coexistence with the old system, and
location. The Four approaches for software installation are:
o Direct Installation Approach o Parallel Installation Approach o Single-location installation Approach o Phased Installation Approach
Direct
Installation
Approach
(^) Consist on switching systems, by turning off the old system, and turning on the new one almost simultaneously. (^) It is the riskiest approach due to the possibility of errors not found during the testing phase of the project. (^) If the new system fails, it could take time to bring the old system up again. (^) It is the longest approach in duration because it requires the complete development and installation of the new system (^) It is the cheapest approach because it does not require the maintenance of two systems simultaneously.
Single-location
Installation
Approach
(^) Also known as pilot installation. Consists of changing systems in strategic sites, or branches, of an organization progressively, until completing the installation at all locations of the organization. (^) The pilot side is chosen because it presents the lower risks of costs and other factors. Making of the single- location approach of a moderated risk installation methodology. (^) This approach allows the combination of other approaches. Different approaches can be used in different sites. (^) Requires the IS department to create extra applications to allow information sharing with pilot sites.
Phased
Installation
Approach
(^) Consist on changing systems in a gradual way. Installing parts of the system at a time, as separate functioning blocks, until the entire system is complete. (^) It provides a low exposure to risks in terms of costs and disruption of business. (^) Allows some departments of the organization to benefit early of the use of some functional modules of the new system. (^) Requires the creation of bridge programs that allow the connection between the old system and the modules of the new system. (^) Requires extra attention from the IS
