A Conceptual Model for Effective Early Warning Information Systems (EEWIS), Saadeldin, Mohamed, Mazen Sherif A., Hassanen Ehab E., and Hegazy Zaher , Proceedings of the 15th International Conference on Enterprise Information Systems, (2013) Abstract

This paper addresses the need for effective early warning information systems (EEWIS) that are capable of predicting future crises and that can help prevent them or reduce their negative effects. The main problem facing any EWIS is the lack of effectiveness. The most effective early warning information systems are characterized by accuracy, flexibility and the ability to detect risks. Effective early warning information systems can empower communities to prepare for and confront risks and disasters. An effective EWIS should be based on a reliable and consistent model, yet the models currently available are mostly deterministic, simplified or inconsistent in application and assumption; thus making them unreliable and impractical. The goals of this paper are to provide guidelines for professionals involved in implementing effective early warning information systems, and to present a novel model for EEWIS that can be adapted to the dynamic needs of the field of crisis management and prep aredness.

Loose coupling between cloud computing applications and databases using a broker service, Nassar, Ebtehal, Ezzat Ehab, and Mazen Sherif , Volume 2, Issue 3, p.88-94,, (2015) Abstract

One of the main characteristics of database driven applications is the strong tight coupling between application and database. Thus, any required change in the database schema leads to change in database access layer. Problems elicit during design phase (specifically in database schema defining and representation), development phase, and maintenance. If the database is shared between different applications, applying changes will be more difficult. The available solutions proposed adding a middle layer that receives query and returns results in a unified form. This research focuses on the limitations of tightly coupled architecture. In addition, it hits the challenge of loose coupling between cloud computing applications and databases by encapsulating the database access code and queries in a separate layer (a broker service) to separate database access code form the application to achieve loose coupling between application and database

Implementation of Customer Service Tracking Using the Active Document Model, Mazen, Sherif A., Fangary Laila M., Bahaa Mohammed, and Farid M. , (2000) Abstract

Any kind of business uses documents, especially those used in paper work activities. The paper work contents hold huge amount of data. This type of data is exchanged between different business partners in form of purchase orders, invoices, offers, contracts …etc. In most cases, the processing control of this data source is poor if not missed because of the unstructured nature of these documents. XML came and brought a new dimension document structure. As the well formed XML documents rely on a predefined schema called XSD, documents may be processed easier and more efficient. The main creators of such daily paper work are the normal users but it is not practical to force them to learn XML concepts to create their documents in XML format.

Specifically, in those fields that include serving customers, service sheets include the details of services are stored in hard or soft copy. Service sheet documents content are gathered from many data sources. The user must ensure that every single piece of data is up to date, at the time of creating the document, as it is stored in its related data source. For example, if the address of the client is changed in the CRM database today, all the next service sheets that will be created should contain the new address. Moreover, the data is valuable but far from straightforward in processing because the unstructured nature of the documents.

In this paper, we present Active Document model and how it can be used to solve the problem of the unstructured nature of the normal paperwork documents. Also, the paper presents a solution that applies the Active Document model. The solution is built for the customer service tracking using the active document model to create the service sheet documents easily, interactively, and in structured XML format. It enables the normal users to create their service sheet documents using the commonly used user interface of their document editors which are referred to by intelligent applications as usual and in the same way they are used to follow but in the needed XML format. It is mainly based on attaching a predefined XSD to the document to define its structure.

Information technology governance in Egypt Research institutions - a case study, Mazen, S. A., Hassanein E., Fahmy A. A., and Hassanein M. K. , Engineering and Technology (ICET), Volume 1 - 7, (2014) Abstract

In all business fields worldwide, the concept of governance is receiving a constantly increasing attention by decision makers as a key means for business success. And, as the vital role of higher education and research institutions is playing in developed and developing countries has become well understood, governance of such institutions emerged as a necessity for country progression. With such an understanding, this paper aims to shed the light on a key area of governance; that is information technology governance (ITG). The paper is divided into two main parts: the first provides a brief background on the topic and positions ITG within the wider scope of governance; and the second part examines the state of ITG in one of Egypt Research institutions using the leading ITG framework - COBIT 5. With minor exception of those processes that are governed by regular laws, results showed a very low capability of IT processes on the average.

Integration Between Software Project Management and Change Management, Mazen, Sherif, Ezzat Ehab, and Afifi Amira Mohamed Gaber Rafaat , Giza, (2016) Abstract

Software projects deviate from their original plans due to changes that may happen during the software life cycle. Project managers depend on their experiences to estimate the effects of these changes on the duration and budget of their projects. Software projects should not deviate or crash with respect to the estimated deadline. Thus, any change should be estimated and studied before executing the plan.
In this thesis, we introduce a framework that integrates Software Project Management (SPM) and Software Change Management (SCM) to achieve the following objectives: First, when a change occurs, we go through the whole change management process before executing the plan. Second,monitoring the activities of the project by preparing and delivering managerial reports based on performance and improvements. When the Change Management Team (CMT) checks for the Change Request (CR), The CMT uses a sheet of rewards and punishments of the people responsible for each CR according to the completion date of the related CR (i.e. early CR means the responsible person will be rewarded; otherwise punished). Third,providing an accurate time variance to record any CRs finished earlier than planned which will result in revising the project plan or any delayed CRs that will derive management to take corrective actions to the project plan.Fourth,helping the management for better decision making in case of any budget deficit or surplus by using the cost variance to monitor the expenditures along the project plan. Fifth, increasing the prediction possibility of early project completion, which may result in revision of the operational processes that depend on the deadline of the project and notifying the higher level of management for further actions.
So,we will mainly focus on the project monitoring and controlling phase because it is one of the most important processes in developing any software project. It controls the operation of the project according to the project plan. In addition, it is one of the CMMI® process areas level 2.

Performance Indicators of Information System Development Life Cycle, lapeep, Evon Kamil, sharkwi M.El, and S.Mazen , (2008) Abstract

Building an information system is a complex process, influenced by many factors, both internal and external. and it pass through different phases starting by planning phase until implementation and operational phase . Each phase should be considered by several elements such as: criteria, constraints, and other changes related to these elements.
And The outputs of the information system should deliver expected results that achieve the requirement and also meet the budget, schedule and also scope.

The performance management process provides an opportunity for the employee and
Performance manager to discuss development goals and jointly create a plan for achieving the goals.
And of course we cannot mange without measure
So we need a performance measurement tools that can ensure the Success of information system. And performance indicators are consider one of theses tools
The Performance indicators save the information systems project from failure that can occurs during the life cycle.
The absent of the Performance indicators may be accuse in wasting the time and effort .and lately we discover that the information system not achieve the organization strategy .and not meet the functional and non functional requirements or the system not meets the scope, budget ,schedule and
That of course make a project fails .so we need Performance indicators in each phase of IS life cycle to measure what we achieved and what not in each phase.
The objective of this research is to study in details what the Performance indicators is and what is its advantage and its tools.
And then find a suitable Performance indicators for the information system project life cycle and also find the Performance indicators that measure if the IS achieve the organization strategy or not.

A Survey on the State of the Art of Enterprise Resource Planning System (ERP), Hassanein, Ahmed Abass A., Mazen S. A., and Hassanein EE , CIIT, Volume 6, p.39-46, (2014) AbstractWebsite

Due to the complexity of the development process of Enterprise Resource Planning Systems (ERP) this survey will meticulously analyze them from different points of views. In the beginning, a brief introduction to the definition of ERP systems showing their main concepts their history and evolution. Then, ERP systems are examined in order to show their essential software development characteristics. In addition, different ERP categorizations from software development point of views are derived from the current research which examined more than seventy of the most popular ERP systems. Furthermore, an overview of the common ERP software architectures are presented. Consequently, the major critical success factors which are needed to be considered when planning to adopt ERP systems is presented. Finally, the trend to include business process concepts into ERP systems is discussed emphasizing those features which are mainly supported in the current ERP systems.

Towards a Specific Approach for Information Systems (IS) Projects Governance, Hamada, Mohamed A., Mazen Sherif A., and Hassanein Ehab E. , (2011) Abstract

IS projects comprise many challenges and difficulties at all development phases, with high risks of such projects end in failure. Failure rates for major IS projects appear to linger around 70%. IS project governance is a new born theory and a nascent field of research. Previous researches in the topic of IS project governance concentrated on high level project governance (general perspective through view the project as one block), they didn’t apply the projects governance in particular perspective according to the project development’ phases and activities. Due to the continuity of high percentages of IS projects failure, specific governance approach for IS projects is a serious attempt to enhance their success through addressing the projects’ failures and defects. Wherever the specific governance approach concentrates on all project’ phases and activates in details, project feasibility study governance is introduced in this research as a sample for applying the specific governance approach for IS projects.

IS projects comprise many challenges and difficulties at all
development phases, with high risks of such projects end in
failure. Failure rates for major IS projects appear to linger around
70%. IS project governance is a new born theory and a nascent
field of research. Previous researches in the topic of IS project
governance concentrated on high level project governance
(general perspective through view the project as one block), they
didn’t apply the projects governance in particular perspective
according to the project development’ phases and activities. Due
to the continuity of high percentages of IS projects failure,
specific governance approach for IS projects is a serious attempt
to enhance their success through addressing the projects’ failures
and defects. Wherever the specific governance approach
concentrates on all project’ phases and activates in details, project
feasibility study governance is introduced in this research as a
sample for applying the specific governance approach for IS
projects.

The Role of the Pre-development Activities in Information Systems Projects’ Failure, Hamada, Mohamed A., Mazen Sherif A., and Hassanein Ehab E. , The 46th Annual Conference on Statistics, Computer Science, and Operations Research issr, (2011) Abstract

Information systems (IS) development projects have high failure rates, lots of researches discussed IS projects failures and listed a huge number of failure reasons, despite that IS projects still have considerably high failure rates. This research looks for the sources of the failures as a new approach to decrease the failure probability of IS projects. Through investigating the failure reasons of IS projects, it has been detected that, most of failure reasons are attributed to the pre-development activities, which begin with the System Service Request (SSR) to initiate the projects and end with developing the project plan to represent a road map to explain how the project will progress through all its phases. Pre-development activities are focal points which have ability to improve IS projects success. So, an avoidance strategy includes many critical success factors for each pre-development activity is introduced as a swift solution for the research problem.
