Criteria

Efficiency: Time, Cost, Effort

Efficiency Criteria: Solution complete processing task’s,

Easy to use, functional

Effectiveness: Goal of system met, Accurate, Relevant

Effectiveness criteria: Is the information used complete, relevant

and accurate.

Why make criteria early: To judge the success of the

solution

Evaluation criteria: Is the data provided complete, acurate and relevant?

Influences on effectiveness of project plan

Was the scope clear?

Was the gannt chart updated?

Was there effective communication?

Evaluating The Solution

Evaluation criteria based on if it meets the SRS

Evaluation stratergy

Make a evaluation stratergy which include's timeframes, criteria used to conduct evaluation

Pseudocode

Subroutine: Contained section that can be called from within any part of program

Function: Task used to pass data back to the calling code

SRS

SRS: Description of intended purpose and environment of solution

Diagrams used to show how users interact with system and how data is transformed into information

Non Functional Requirements:

Usability: How easy it is for user to use the solution

Reliability: How long solution can perform its required function in the environment

Robustness: How well solution responds to poor use or inputs

Maintability: How easy solution can be fixed

Portability: Can solution be moved to other environments

Constraints on solution

Economical factors: Budget and scale of project

Technical factors: Security features is the solution fast, How fast can solution run, Does computer have enough room.

Gannt Chart

(Line) Dependency: Task's which depend on

(Diamond) Milestone: Certain stage which must be reached

Use Case

Include: Show's link between use cases

Extends: Shows that the functionallity of a use case contributes to another use case

Testing

Acceptance testing: used to determine if the requirements of a solution have been met.

Usability testing: used to test if the solution is or will be easy to use for the user.

Project

What is in a project: Time Cost effort and the scope

Constraints on the effectiveness of her project plan

Coding issues

Conflict with schedule

Gannt chart update
