A Framework for Facilitating the Simultaneous Implementation of the SAFe 5.1 and ITIL 4
, M.Sc. Thesis Sharif University of Technology ; Shokraneh Moghaddam, Shokraneh (Supervisor)
Abstract
One of the most widely used approaches for managing Agile product development in large software organizations is the Scaled Agile Framework (SAFe). Additionally, many organizations use ITIL as a framework for providing services around these products. Neither of these management methods has provided a precise opinion on the other's domain, which can create a realm of ambiguity when implementing both of these management approaches simultaneously. This research attempts to mitigate the ambiguities associated with the concurrent use of SAFe 5.1 and ITIL 4 management methods by proposing a framework to facilitate their implementation. In this study, after identifying the gaps between these...

This said, it is needless to mention that it has also encountered some difficulties and setbacks along its way to educational dominance. User satisfaction or customer satisfaction is one of the major means by which one can evaluate the success of such programs. Organizations on the other hand are incorporating behavioral...
A Methology for Implementing ITIL V3 based on PMBOK
, M.Sc. Thesis Sharif University of Technology ; Shadrokh, Shahram (Supervisor)
Abstract
PMBOK is a standard that is the subset of Project Management Knowledge and includes all areas. ITIL is a framework that allows IT organizations using best practices in IT Service Management. Both of them includes some process that during implementation and execution should act based on them. The goal of developing a methodology for implementing ITIL V3 based on PMBOK is executing a comparison mapping for connecting these two difference fields. IT managers know about ITIL implementation, but most of project managers are not familiar about it. If we guess that implementing ITIL V3 is a project, a project manager can do it based on PMBOK. With mapping these two fields, project managers are able...

Designing a General IT Security System Using RAISE Formalism
, M.Sc. Thesis Sharif University of Technology ; Solaiman Fallah, Mehran (Supervisor)
Abstract
Security has become more important in IT systems. Thus, to protect such systems from related potential threats and harms, robust and dependable security solutions should be devised. In designing security systems, a number of other issues such as assurance and verifiability are also of concern. Due to their mathematical nature, formal methods are very suitable for the above purposes. Using these methods, one can accurately define a system, its boundaries, and the requirements from design. It also makes it possible to verify that the design meets the requirements. In this dissertation, we propose a general IT security system using RAISE specification method. To do so, the specification...
QoS-aware water-filling for real-time transmission in OFDMA systems
, Article 2011 18th International Conference on Telecommunications, ICT 2011, 8 May 2011 through 11 May 2011, Ayia Napa ; 2011 , Pages 84-89 ; 9781457700248 (ISBN) ; Khalaj, B. H ; Froushani, M. H. L ; Sharif University of Technology

Abstract
In this paper, we propose a distributed rate and power allocation algorithm for real time traffic by using second order statistics of the channel. Our method minimizes the average delay of transmission over the fading channel. We assume that each sub carrier relies on its own buffer, and a constant arrival rate from higher layer application arrives at input buffers of each sub-carrier. This constant rate is optimally distributed through individual sub-rates transmitted over each sub-channel. Optimum power coefficients are also derived to minimize the average delay of transmission. In addition, collision and buffer overflows are taken into account while achieving acceptable throughputs
Process patterns for agile methodologies
, Article IFIP International Federation for Information Processing ; Volume 244 , 2007 , Pages 222-237 ; 15715736 (ISSN); 9780387739465 (ISBN) ; Ramsin, R ; Sharif University of Technology
2007
Abstract
The need for constructing software development methods that have been tailored to fit specific situations and requirements has given rise to the generation of general method fragments, or process patterns. Process patterns can be seen in some third-generation integrated methodologies (such as OPEN) and in Method Engineering approaches where they are used as process components. They have also been presented as components in generic software development lifecycles where they represent classes of common practices in a specific domain or paradigm; object-oriented process patterns are well-known examples. Agile methodologies, however, are yet to be thoroughly explored in this regard. We provide a...
