Inadequate software engineering has led to failure of modern softwares.

Causes of software failures
----------
1. increasing demand: software developers are tasked to develop softwares that solve more complex solutions and are often given short time. the existing software engineering techniques are therefore not able to cater for this complexity.
2. low expectation: most software developers develop softwares without using software engineering techniques which often cause software failures and unreliable softwares

Attributes of a good software:(M.A.D.E) Maintainability: it should be able to evolve in order to fit new needs or suit new customers Acceptability: it must meet the need for which it was developed for and must be usable for its users Dependability and Security: it must not cause physical damage or be open to malicious attackers for exploits Efficiency: it must not waste system resources like memory, disk space, e.t.c
Others are D.R.I.P Distributability,Reusability,Interoperatability,Portability

software engineering is an aspect of engineering discipline that focuses on all the aspect of software development production

Fundamental software engineering activities DEVS: software development, software evolution, software validation, software specification

Difference between software engineering and computer science: computer science focuses on the theories and fundamentals of software development while software engineering focuses of the practicalities of developing and delivering useful software

Types of software packages
-Generic products: these are softwares developed and sold to the open market to meet the need of various end users. the programmers initiates the software requirements
