1.2 Problem Statement

Project Management System (PMS) had been widely used in organizations which allow everyone (include Project Manager or Project Member) related to the project can get the most up-to-date information anytime, anywhere. Project Management is not only useful in software development, but also in many mature processes, such as building a house or bridge. Many years ago, the age without software, project management was done through pen and paper. Project Managers wrote down their design and task required in order to finish their final goal, and used traditional way such as getting the project task status by phone or mail. However, it’s hard to get a whole view of the entire project. With the support of IT technology, it is not difficult to implement an online PMS to support those real-time project management activities.

A Project is an information collection which includes general information such as Project Title, Proprietor, Start Date and Finish Date, etc, and a number of related tasks in order to finish the project which planned by a people who is in charge on the project, called Project Manager. A Task usually assign to a people (usually called project members) who is familiar with it. For management purposes, a task usually includes a Task Title which describes the task, a Resource about the team member assigned to the task, a Task Start Date and a Task Finish Date which indicate the time of the task started and finished actually. Other information may also be logged into task information which could aim on advance analysis activities such as process performance analysis to project members. Compare to most of the PMS available today, this system should provide an extra support on large projects. A large project mentioned here indicates a long-term or multi-phase project which may be controlled by several project managers. Like a normal, regular project, a large project itself will be assigned a project manager for overall project planning. Additionally, the project manager may separate this large project (usually called Parent Project) into some smaller projects (usually called Child Projects) and assign different project managers for those smaller projects. The relationship between the parent project and child projects is called “Hierarchical”. In conclusion, the project separation has already been a practical strategy and adapted in enterprises already but not widely supported by most PMS available today. A major purpose of this Hierarchical Project Management System (HPMS) is designed to provide a system which could handle this situation.

1.3 System Context Diagram

Figure 1 shows the System Contet Diagram of this Hierarchical Project Management System.

Figure 1, The System context diagram of the Hierarchical Project Management

System

Design the software to support a computerized banking network including both employees workstation (used by project manager and project member) and IT staff’s workstation within coporate network—the corpNet (might be extended to across the Internet in the future). The administrator use it’s workstation (located in MIS department, denoted in “IT staff’s workstation”; Other regular users include project managers and members use their laptop which denoted in “Employee’s Workstation” to access the “Central Management System”, which hosted in headquarter’s server room.

The Central Management System provides central host applications and a storage for PMS system, regular users and administrator access this system through those applications hosted in Central Management System. Each user of this system which identified by their ID and role will got a set of system functions, to support their responsibilities of project amangement.

1.7 Data Dictionary

Term Definition or Description

Administrator Represents a user with administrator role associated. A

user with administrator permission usually performs system-wide operations such as user management and project registration.

Child Project See Project

Master Project See Project

Project A project used here is represent a completed work

coorsponding to a business contract. A project should be assigned a project manager for task planning, resource planning and progress monitoring. A project could associated with a number of tasks in order to fulfill the contract’s requirements. Sometimes a large project (called Master Project) could separate into some smaller projects (called Child Project) for better manageability.

Project Manager Represents a user with project manager role associated.

A user with project manager permission usually performs project-wide operations such as project separation and resource allocation.

Project Member Represents a user with project member role associated. A

user with project member permission usually performs task-wide operations such as task execution status feedback.

Role; User Role Role, or User Role represents one of system defined

permissions. A role could be associated to a user, this indicates a user is granted a set of permission which defined with the specific role.

There are three system-defined roles including administrator”, project manager and project member.

Task A Task is a unique job to be completed for a specific

project.

User A user is a basic concept of valid system users. With

some authorization, a user can be associated with one or many system-define roles (see Role) to perform their jobs.
