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.

Assessment of Cloud Computing Adoption Models in E-government Environment, Ali, Kh. E., Mazen Sh. A., and Hassanein EE , (2017) Abstract

Most of developing countries are now experiencing revolution in e-government to deliver
fluent and simple services for their citizens. However, government sectors face many challenges in
modernization its e-governments’ services and its infrastructure. These challenges may lead to failure
of improving current services or developing new one. Therefore, there is a need for a solution to
overcome it. Cloud Computing plays a vital role to solve these problems. So, some of governments are
now tending to adopt cloud computing in their agencies for utilizing their benefits and overcome on e-
government challenges.
This paper demonstrates cloud computing, its characteristics, basic delivery models and deployment
models. It analyzes and reviews the literature proposed models of cloud computing adoption in e-
government environment. Finally, it compares between these models and classifies it to different
classifications from functionally perspective.

Framework for Integrating Software Project Tasks and Change Requests., Gaber, Amira M., Mazen Sherief, and Hassanein. Ehab E. , International Journal of Computer Applications , Volume 125, Issue 12, (2015) Abstract

"Most of the software projects may deviate from their original plans during the Software Life Cycle in the organization. This deviation typically results from the changes that happed and
the project manager depends on his experience to estimate the effects of the change. This may affect the duration and budget of the project. It is important that the software project should not deviate or crash according to the estimated deadline. Thus any change should be estimated and discussed before implementation. In this paper will introduce a framework that integrates the Software Project Management (SPM) with Software Change Management (SCM) to achieve the following objectives: Firstly, optimizing the Change Management Process in a project and track the whole Change Requests. Secondly, monitoring if the software project finished early by revising the project plan w.r.t the actual schedule to shrink the project deadline. And execute the consequences processes according to finish early Thirdly, the actual results with performance will be tracked against the project plan and any variances should be analyzed. In addition, facilitating distribution of tasks (Change Requests) and availability of information. Finally, providing more control over a project when the technical issues can be raised and turned to managerialissues to take corrective actions if: the project takes more time, the project takes more cost or both of them"

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.

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

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 PROPOSED FRAMEWORK FOR THE ORGANIZATION READINESS ASSESSMENT OF IT INNOVATION ADOPTION IN E-GOVERNMENT ENVIRONMENT, Ali, Kh. E., Mazen Sh. A., and Hassanein EE , (2017) Abstract

Most of developing countries are now experiencing revolution in e-government to deliver
fluent and simple services for their citizens. But, the organization will face three main problems if it
decided to modernize its IT infrastructure; firstly, there are many solutions of new technologies, how to
choose between them. Secondly, what is the impact of the factors affect on those solutions? Thirdly,
what is the degree of readiness each of these factors to comply this new changing? Therefore, a
systematic approach to measure organization readiness for adopting this new solution is needed, this
paper proposes a practical framework helps in answering these questions and assists decision makers
in estimating organization readiness for adopting all IT suggested solutions and to compare between
these solutions. Whereas, it will use Multi-Criteria Decision Making method to rank the alternatives,
taking into account all the attributes and factors affect the result, finally, it assess the degree of
readiness of these factors to accept the preferred solution.

This paper is concerned with the evaluation of perfOrmance indicators of
Information Systems Project Management (IS-PM). It clarifies the relationships
between IS-I’M domains, performance metrics. quality metrics, and performance
indicators. This paper presents an elaborated list of quality metrics for IS-PM. Based
on. these IS-PM quality metrics and a combination of statistical techniques, we built a
model for calculating IS-PM performance indicators. The quality reviewers can use
this model to evaluate and track the performance of IS projects managers.
