Assignment #1-Solution
Chapter 1: Introduction
1. What are the two fundamental types of software product?
Generic products that are designed to meet the needs of many different
customers.
Customized products designed to meet the specific needs of a single
customer.
2. What is a software process?
The software process consists of activities that are involved in developing software
products. Basic activities are software specification, development, validation and
evolution.
3. What is a software process model?
Give 3 examples of the types of software process model?
A simplified representation of a software process, presented from a specific
perspective.
Examples of process perspectives are
- Workflow perspective - sequence of activities;
- Data-flow perspective - information flow;
-Role/action perspective - who does what.
Generic process models
- Waterfall;
- Iterative development;
- Component-based software engineering.
4. What are software engineering methods?
Give 3 examples of software engineering methods
Methods are organized ways of producing software. They include suggestions for
the process to be followed, the notations to be used, rules governing the system
descriptions which are produced and design guidelines.
They areStructured approaches to software development which include system
models, notations, rules, design advice and process guidance.
Examples of software engineering methods
- Function Oriented methods: such as SSAD( Structured Systems Analysis and
Design).
- Object Oriented methods.
- Unified approach built around UML (Unified Modelling Language)
5. What is the role of CASE tools? Give 2 examples of integrated CASE tools?
Software systems which are intended to provide automated support for software
process activities, such as requirements analysis, system modelling, debugging
and testing
Examples of integrated CASE tools
1
- Rational Rose from IBM
- IDS (Internet Development Suite) from ORACLE
Chapter 5: Project management
1. List 5 common project management activities.
Proposal writing.
Project planning and scheduling.
Project costing.
Project monitoring and reviews.
Personnel selection and evaluation.
Report writing and presentations.
2. What is the difference between a milestone and a deliverable?
Milestones are the end-point of a process activity.
A project milestone is a predictable state where a formal report of progress
is presented to management.
Deliverables are project results delivered to customers.
3. Draw a diagram to illustrate the main activities in the project scheduling process?
Project scheduling involves preparing various graphical representations showing
project activities, their durations and staffing.
4. Explain how bar charts and activity networks give different views of a project
schedule.
Graphical notations are used to illustrate the project schedule.
Activity charts show task dependencies and the critical path.
Bar charts show schedule against calendar time.
5. What are the typical sections included in a project plan document?
Introduction. This briefly describes the objectives of the project and sets out the
constraints (e.g., budget, time, etc.)
Project organisation. This describes the ways in which the development team is
organized, the people involved and their role in the team.
Risk analysis. This describes possible project risks
Hardware and software resource requirements. This specifies the hardware
and the support software required to carry out the development.
Work breakdown. This sets out the breakdown of the project into activities
and identifies the milestones and deliverables.
Project schedule. This shows the dependencies between activities,
2
the estimated time required to reach each milestone and
the allocation of people to activities.
Monitoring and reporting mechanisms. This defines the management reports
that should be produced, when these should be produced and the monitoring
mechanisms used.
6. Consider the following project:
