Challenges and influential factors in ERP adoption and implementation
The adoption and implementation of Enterprise Resource Planning (ERP) systems is a challenging and expensive task that not only requires rigorous efforts but also demands to have a detailed analysis of such factors that are critical to the adoption or implementation of ERP systems. Many efforts have been made to identify such influential factors for ERP; however, they are not filtered comprehensively in terms of the different perspectives. This paper focuses on the ERP critical success factors from five different perspectives such as: stakeholders; process; technology; organisation; and project. Results from the literature review are presented and 19 such factors are identified that are imperative for a successful ERP implementation, which are listed in order of their importance. Considering these factors can realize several benefits such as reducing costs and saving time or extra effort
Rounding of a first-order quantum phase transition to a strong-coupling critical point
We investigate the effects of quenched disorder on first-order quantum phase
transitions on the example of the -color quantum Ashkin-Teller model. By
means of a strong-disorder renormalization group, we demonstrate that quenched
disorder rounds the first-order quantum phase transition to a continuous one
for both weak and strong coupling between the colors. In the strong coupling
case, we find a distinct type of infinite-randomness critical point
characterized by additional internal degrees of freedom. We investigate its
critical properties in detail, and we discuss broader implications for the fate
of first-order quantum phase transitions in disordered systems.Comment: 5 pages, 4 figure
Strong-randomness infinite-coupling phase in a random quantum spin chain
We study the ground-state phase diagram of the Ashkin-Teller random quantum
spin chain by means of a generalization of the strong-disorder renormalization
group. In addition to the conventional paramagnetic and ferromagnetic (Baxter)
phases, we find a partially ordered phase characterized by strong randomness
and infinite coupling between the colors. This unusual phase acts, at the same
time, as a Griffiths phase for two distinct quantum phase transitions both of
which are of infinite-randomness type. We also investigate the quantum
multi-critical point that separates the two-phase and three-phase regions; and
we discuss generalizations of our results to higher dimensions and other
systems.Comment: 9 pages, 6 eps figures, final version as publishe
America’s informal empire - what really went wrong in the Middle East
In this edited excerpt from the introduction to What Really Went Wrong, Fawaz A Gerges argues that US interventionism during the Cold War – especially in Iran and Egypt – steered the Middle East away from democracy towards authoritarianism, shaping the region’s political and economic landscape for decades to come
The New Islamists: pluralism and minorities?
In his analysis of Islamist governance on pluralism and minorities Fawaz A. Gerges concludes this special series of posts commissioned by LSE IDEAS exploring Islamism and the Arab Spring. The series also includes articles on the history of political Islam, Tunisia, Egypt and Libya
