cs562 - Software Engineering II

Last time we covered Effort/Time estimation

Including GQM, Time estimation with past experience, COCOMO, COCOMO II, and Function Points

This time we will look at OO function estimation and Project status tracking with earned value.

OO Function estimation

		1. Est. the # of classes
		2. Categorize UIs
			No UI		2.0
			Text-based	2.2
			GUI		2.5
			Complex	3.0
		3. Compute #UI classes = # of non-UI classes * UI categorization
		4. #classes = #UI classes + # of non-UI classes
		5. Multiply the total number of classes by a value between 15 and 20 to determine the number of person-days required

	3 tasks , 10, 15, 30 person months
	Calc bcw
	Effort so far 
	Budgeted cost of work (BCW) - estimated effort for each task
	Budgeted cost of work scheduled (BCWS) - sum of estimated efforts sum(BCW) at date
	Budget at completion (BAC) - sum (BCW)
	Budgeted cost of work performed (BCWP) - sum (estimated effort for completed tasks) on particular date
	Actual cost of work performed (ACWP) - sum (actual effort for completed tasks) on particular date

	Earned Value = BCWP/BAC
	Cost Variance = BCWP - ACWP
	Schedule Variance = BCWP - BCWS

	Evidence Based Scheduling
		Base scheduling upon past experiences


We will also look at project management and risk assessment
	Project management is different from software engineering in that it follows a management
	process to ensure the software engineering process is followed.

	Includes Planning, Organizing, Monitoring, and Adjusting

	Planning
		Want to satisfy customer needs
			Include all desired project attributes
			Hit target milestones
			Ensure team members operate effectively and with high morale
			Make sure required tools/resources are available and effectively utilized

		In planning phase answer following questions
			What is the nature of the SW project, who is sponsoring the project, who are
			users?
			Requirements
			Delieverables?
			Known risks?
	
		It is helpful to quantify goals
			What is high quality?
			What is high reliability?
			Etc.
	
		Want
			Risk identification
			Risk prioritization
			Risk mitigation

	Organizing
		Tools to use
		Tasks and schedule
		Content and deliverables
		Goals and measurement
		Risks

	Monitoring, including the following helps to deal with risk
		Collection of project information
		Analysis and evaluation of the collected data
		Presentation and communication of this information

		How to monitor?
			Trend analysis and control charts
			Data correlation and regression analysis
			Moving averages and data smoothing
			Model building for interpolation and extrapolation

		Useful tools include
			Pie charts
			Histograms
			Bar charts

	Adjusting
		Resources
		Schedule
		Project content
