The Process of Initiating and Planning IS Development Projects

FIGURE 5-1Systems development life cyclewith project initiation andplanning highlighted


The Process of Initiating and Planning IS Development Projects (Cont.)

Project initiation focuses on activities designed to assist لمساعدة in organizing a team to conduct(إجراء) project planning.



Establishing the Project Initiation Team. Establishing a Relationship with the Customer. Establishing the Project Initiation Plan. Establishing Management Procedures. Establishing the Project Management

Environment and Project Workbook. Developing the Project Charter.



The key activity of project initiation is the development of the project charter. A short document that is prepared for both internal

and external stakeholders المصلحة أصحاب Provides a high-level overview of the project Useful communication tool that helps to assure that

the organizations and other stakeholders understand the initiation of a project



A project charter typically contains:( المشروع (عقد

Project title and date of authorization Project manager name and contact information Customer name and contact information Projected start and completion dates Key stakeholders, project role, and responsibilities Project objectives and description Key assumptions or approach Signature section for key stakeholders.



The key activity of project planning is the process of defining clear, discrete activities and the work needed to complete each activity within a single project.

The objective of the project planning process is the development of a Baseline Project Plan (BPP) and the Project Scope Statement (PSS).


Elements of Project Planning Describe project scope, alternatives,

feasibility. Divide project into tasks. Estimate resource requirements and

create resource plan. Develop preliminary schedule. Develop communication plan.


Elements of Project Planning (Cont.) Determine standards and

procedures. Identify and assess risk. Create preliminary budget. Develop a statement of work. Set baseline project plan.


Deliverables and Outcomes

intangible economic benefits and costsThe technical and organizational feasibility of

the proposed system


Deliverables and Outcomes (Cont.)

phaseContains the best estimate of a project’s

scope, benefits, costs, risks, and resource requirements

complete the project


Assessing Project Feasibility

Economic Technical Operational Scheduling Legal and contractual والتعاقدية القانونية Political


Assessing Project Feasibility (Cont.) Economic feasibility: a process of

identifying the financial benefits and costs associated with a development projectOften referred to as a cost-benefit analysisProject is reviewed after each SDLC phase in

order to decide whether to continue, redirect, or kill a project


Determining Project Benefits

Tangible benefits refer to items that can be measured in dollars and with certainty.

Examples include: reduced personnel expenses, lower transaction costs, or higher profit margins.


Determining Project Benefits (Cont.) Most tangible benefits will fit within the following

categories: Cost reduction and avoidance Error reduction Increased flexibility Increased speed of activity Improvement of management planning and control Opening new markets and increasing sales

opportunities


Determining Project Benefits (Cont.) Intangible benefits are benefits derived from

the creation of an information system that cannot be easily measured in dollars or with certainty. May have direct organizational benefits, such as the

improvement of employee morale معنويات. May have broader societal implications, such as the

resource consumption.


Determining Project Costs

Tangible cost: a cost associated with an information system that can be measured in dollars and with certainty

IS development tangible costs include:Hardware costs,Labor costs, orOperational costs including employee training

and building renovations التجديدات.


Determining Project Costs (Cont.)

Intangible cost: a cost associated with an information system that cannot be easily measured in terms of dollars or with certainty

Intangible costs can include:Loss of customer goodwill,Employee morale, orOperational inefficiency.



One-time cost: a cost associated with project start-up and development or system start-up

These costs encompassتشمل activities such as: Systems development, New hardware and software purchases, User training, Site preparation, and Data or system conversion.



Recurring cost : a cost resulting from the ongoing evolution(تطور) and use of a system

Examples of these costs include: Application software maintenance, Incremental data storage expenses, Incremental اإلضافية communications, New software and hardware leases اإليجار and ,عقود Supplies and other expenses (i.e. paper, forms, data

center personnel).


Determining Project Costs (Cont.) Both one-time and recurring costs can

consist of items that are fixed or variable in nature.

Fixed costs are billed or incurred at a regular interval and usually at a fixed rate.

Variable متغير costs are items that vary in relation to usage.

The Time Value of Money

Time value of money (TVM): the concept that money available today is worth more than the same amount tomorrow

The Time Value of Money Net Present Value (NPV)

Discount rate: the rate of return used to compute the present value of future cash flows (the cost of capital)

Assessing Technical Feasibility

Technical feasibility: a process of assessing the development organization’s ability to construct a proposed system


Assessing Technical Feasibility

The potential consequences of not assessing and managing risks can include the following: Failure to attain expected benefits from the project, Inaccurate project cost estimates, Inaccurate project duration estimates, Failure to achieve adequate(مالئم) system

performance levels, and Failure to adequately integrate the new system with

existing hardware, software, or organizational procedures.


Project Risk Factors Project size

Team size, organizational departments, project duration, programming effort

Project structure New vs.(مقابل) renovated (تجديده)system, resulting

organizational changes, management commitment(إلتزام), user perceptions(تصورات)

Development group Familiarity ( والتناسق with platform, software, development(األلفة

method, application area(مجال), development of similar(مماثلة) systems

User group Familiarity with IS development process, application area, use

of similar systems


Assessing Technical Feasibility (Cont.) Risk can be managed on a project by:

Changing the project plan to avoid risky factors.Assigning(تكليف) project team members to carefully

manage the risky aspectsSetting up monitoring methods to determine

whether or not potential risk is, in fact, materializing. محتمل خطر هناك كان إذا ما لتحديد الرصد طرق إنشاءال ام ،


Assessing Technical Feasibility (Cont.) The four primary factors associated with the

amount of technical risk on a given project are: Project size, Project structure, The development group’s experience with the

application and technology area, and The user group’s experience with systems

development projects and the application area.


Assessing Technical Feasibility (Cont.) Four general rules emerged as technical

risk assessments:Larger projects are riskier than smaller projects.A system in which the requirements are easily

obtained and highly structured will be less risky than one in which requirements are messy, ill structured, ill defined, or subject to the judgment(حكم) of an individual.


Assessing Technical Feasibility (Cont.)

The development of a system employing commonly used or standard technology will be less risky than one employing novel or nonstandard technology.

A project is less risky when the user group is familiar (دراية)with the systems development process and application area than if unfamiliar.


Assessing Technical Feasibility (Cont.)

Assessing Other Feasibility Concerns Operational

Does the proposed system solve problems or take advantage of opportunities?

Scheduling Can the project time frame and completion dates

meet organizational deadlines? Legal and Contractual

What are legal and contractual ramifications(التداعيات) of the proposed system development project?

Political How do key stakeholders view the proposed system?
