Quality screening in an information technology process

Abstract

Purpose -The purpose of this paper is to propose a methodology that may aid in assessing information technology (IT) quality characteristic optimisation through the use of simple and robust tools with minimal effort. Design/methodology/approach -Non-linear saturated fractional factorial designs proposed by Taguchi receive robust data processing by the efficient nonparametric test of Jonckheere and Terpstra. Findings -The paper finds that e-mail quality improvement is achieved by collecting data through an unreplicated-saturated L 9 (3 4 ) design. Active influences are attributed to the e-mail volume and the receiving hardware type.Research limitations/implications -The overall efficiency of the method is greatly enhanced due to incorporation of a nonparametric analysis tool that is known to perform effectively when data availability is minimal. The method does not succumb to normality and multi-distributional effects which may easily handicap the decision-making process when derived from other mainstream methods. Practical implications -There are obvious professional and pedagogical aspects in this work aiming at IT quality practitioners offering facilitation towards implementing robust techniques while suppressing quality costs. It is noteworthy that nonparametric data processing improves on the ability to make predictions over Taguchi's regular Design of Experiments (DOE) formulation for small sampling conditions. Originality/value -This method embraces designing efficiency by non-linear orthogonal arrays with multi-level order statistics providing the weaponry to deal with quality optimisation in complex environments such as those in the IT area. The value of this work may be appreciated best by quality managers and engineers engaged in routine quality improvement projects in the area of information systems which also augments the general database of quality-related testing cases.

Examining the role of dialogic communication and trust in donation-based crowdfunding tasks using information quality perspective

“…The reasons for the success or failure of DBC is critical to understand because the financial goal is linked to disaster recovery operations, which needs immediate attention. To avoid service failure of a donation-based crowdfunding platform, we explore the principles of quality management (van Kemenade and Hardjono, 2019; Besseris, 2010) to understand its role in comprehending and improving operational performance in the case of a DBC platform. The cash flow on DBC platforms also source data of donors in the form of their credentials, their donation pattern and the cause of donation.…”

Concurrent multiresponse non-linear screening: Robust profiling of webpage performance

“…Addressing the multi-response multi-factorial profiling case has been dealt with recently using nonparametrics which includes the additional option to prioritize the profiled traits for a group of unreplicated responses (Besseris, 2009c). A pure order-statistics single-response methodology has been proposed for a non-linear unreplicated-saturated OA scheme assorted with an illustrative application drawn from the area of improving the quality performance of an information technology system (Besseris, 2010a).…”
