Introduction
Computer science is still a young field. The first
computers were built in
the mid 1940s
A model of the whole system is
developed which, when encoded in some programming
language, solves the problem for the user.
Design
An important activity not identified separately is _______. Since many projects are pressed for time, the ________ tends to get the worst of it. However, it is important to realize that software which is not sufficiently documented is bound to incur high costs later on.
Documentation
Need of software project management
Time, Cost, Quality
It is performed before the production of software actually starts.
Project Planning
The time when people started to realize that programming
techniques had lagged behind the developments in
software both in size and complexity.
1960s
After delivery of the software, there are often errors that have still gone undetected.,
Obviously, these errors must be repaired. In addition, the actual use of the system can lead
to requests for changes and enhancements.
Maitenance
The _______________ should be task-oriented in the sense that the
software to be delivered should support users in their task environment.
Likewise, the user documentation should be task-oriented
Software development
A person who undertakes the responsibility of executing the software project. He/she is thoroughly aware of all the phases of SDLC that the software would go through.
Software Project Manager
It defines the scope of project; this includes all the activities, process need to be done in order to make a deliverable software product. ______________ is essential because it creates boundaries of the project by clearly defining what would be done in the project and what would not be done.
Scope Management
The application of a
systematic, disciplined, quantifiable approach to
the development, operation, and maintenance of
software; that is, the application of engineering to
software
Software engineering
It is wrong to say that ______ is a phase following
implementation. This suggests that you need not bother about this phase until implementation is finished. This is not true. It is even fair to say that
this is one of the biggest mistakes you can make.
Testing
4 kinds of Maintenance activities
•Corrective maintenance
•Adaptive maintenance
•Perfective maintenance
•Preventive maintenance
4 types of managing people:
Clue: ALMS
Managing People
•Act as project leader
•Liaison with stakeholders
•Managing human resources
•Setting up reporting hierarchy etc.
For an effective management accurate estimation of various measures is a must. With correct estimation managers can manage and control the project more efficiently and effectively.
Project Estimation
This concerns the
construction of large programs.
Software engineering
A kind of programming language. Its syntax and semantics
are in general less strict, so that algorithms can be formulated at a higher,
more abstract, level.
Pseudocode
The job pattern of an IT company engaged in software
development can be seen split in two parts. Ano yung mga yun?
•Software Creation
•Software Project Management
6 activities in managing project.
Clue: DMMRTA
Managing Project
•Defining and setting up project scope
•Managing project management activities
•Monitoring progress and performance
•Risk analysis at every phase
•Take necessary step to avoid or come out of problems
•Act as project spokesperson
4 types of Project Estimation.
Clue: SETC
• Software size estimation
• Effort estimation
• Time estimation
• Cost estimation
The goal of this phase is to get a complete description of the
problem to be solved and the requirements posed by and on the environment in which the
system is going to function.
Requirements engineering
During this phase, we concentrate on the individual
modules. Our starting point is the module's specification. It is often
necessary to introduce an extra 'design' phase, the step from module
specification to executable code often being too large. In such cases, we may
take advantage of some high-level, programming-language-like notation,
such as a pseudocode.
Implementation
The complete procedure of software development from requirement gathering to testing and maintenance, carried out according to the execution methodologies, in a specified period of time to achieve intended software product.
Software Project
3 Software Management Activities
Clue: PSP
•Project Planning
•Scope Management
•Project Estimation
1. This technique assumes the software as a product of various compositions.
2. Estimation is done on behalf of number of line of
codes in the software product.
3. Estimation is done on behalf of number of function points in the software product.
1. Decomposition Technique
2. Line of code
3. Function points
