Presentation Transcript

Programming Engineering of Standalone Programs Prof. Ruth Dameron, dameron@colorado.edu Course site with course materials is under WebCT Need an identikey and secret word Call 303-735-HELP

Course site substance Go to http://webct.colorado.edu/Login in the event that you have identikey and client watchword Lecture material - PowerPoint documents Print in "freebee" or in Notes organize "Immaculate highly contrasting" Homework assignments Some extra things, for example, short articles or book extracts Other course data syllabus with perusing assignments, occasions reading material data, PowerPoint address records last test of the year data available time, contact data

Part of an entire Software Engineering Certificate - 9 hrs graduate credit http://ece.colorado.edu/~swengctf/Software Engineering of Standalone Programs Software Engineering of Multiprogram Systems Software Engineering of Distributed Systems The connections at the above site indicate course materials that are not under control of WebCT. Their motivation is to give you a chance to perceive what is shrouded in the 3 courses Warning: Lecture takes note of that match the ones I use in class PLUS your homework assignments are the ones that are under WebCT.

Project Success Factors Other User Involvement Ownership Executive Management Support Smaller Project Milestones Realistic Expectation Competent Staff Clear Statement of Requirements Proper Planning Clear Vision and Objectives Hard-Working Focused Staff

Top Ten Project Success Factors 1. client association 2. official administration bolster 3. clear articulation of prerequisites 4. appropriate arranging 5. practical desires 6. littler venture developments 7. skilled staff 8. possession 9. clear vision and destinations 10. persevering, centered staff

Properties of Challenged Projects Other Unclear Objectives Lack of User Involvement Inc. Necessities & Specs Changing Requirements & Specs Unrealistic Time Frame Unrealistic Expectation Technology Incompetence Lack of Resources Lack of Executive Support New Technology

Top Ten Challenged Project Factors 1. Absence of client inclusion 2. Inadequate necessities and determinations 3. Changing prerequisites and details 4. Absence of official bolster 5. Innovation Incompetence 6. Absence of Resources 7. Unreasonable desires 8. Indistinct goals 9. Farfetched time period 10. New innovation

Incomplete Requirements Other Didn't Need any Longer Lack of User Involvement Changing Requirements & Specs Lack of Resources Lack of IT Management Technology Illiteracy Unrealistic Expectations Lack of Executive Support Lack of Planning Properties of Impaired Projects

Top Ten Impaired Project Factors 1. Fragmented prerequisites 2. Absence of client inclusion 3. Absence of assets 4. Farfetched Expectations 5. Absence of official bolster 6. Changing prerequisites & specs 7. Absence of arranging 8. Didn't require any longer 9. Absence of IT administration 10. Innovation absence of education

Requirements Engineering

Requirements Elicitation Identify applicable wellsprings of necessities (typically client) Determine what data is required. Examine the assembled data, searching for suggestions, irregularities, or uncertain issues Confirm your comprehension of the necessities with the source Synthesize fitting proclamations of the prerequisites Software Requirements

Outcome of good elicitation exercises The purchaser/client completely investigate and completely comprehend their prerequisites. The purchaser/clients can isolate their needs from their requirements. The purchaser/clients can comprehend the abilities and constraints of PC innovation. The purchaser/clients comprehend the option arrangements and effect of every option. The purchaser/clients comprehend the effect of the prerequisites on the engineer and themselves. The engineers are taking care of the correct issue. The designers have certainty that the framework to be conveyed is achievable to assemble. The designers have the trust and certainty of the client. The engineers pick up space learning of the framework

Outcome of poor elicitation exertion The client likely will be disappointed. The client and designer need to adapt to continually evolving necessities. The engineer is taking care of the wrong issue. The designer has a troublesome time fabricating the framework.

Project Success Factors User Involvement Executive Management Support Other Smaller Project Milestones Ownership Clear Statement of Requirements Realistic Expectation Proper Planning Competent Staff Clear Vision and Objectives Hard-Working Focused Staff Requirements Elicitation User Involvement Criteria 2 Do I have the privilege user(s)? Did I include the user(s)early and frequently? Do I have a quality user(s) relationship? Do I make contribution simple? Did I discover what the user(s) needs? Programming Requirements

Requirements Analysis Obtain Requirements from every single conceivable source (incorporate however not restricted to): perception and estimations of the present framework interviews with clients current framework documentation plausibility considers models and models focused investigation Software Requirements

Quality properties

Requirements Specification Software work Performance External Interfaces Design Constraints Quality Attributes Software Requirements

Statement of Requirements Criteria Project Success Factors Do I have a succinct vision? Do I have a useful investigation? Do I have a hazard evaluation? Do I have a business case? Can I gauge the venture? Programming Requirements

Requirements Verification To distinguish and resolve programming issues and high hazard issues right on time in the product cycle. The confirmation that the product prerequisite detail is in consistence with the framework necessities, adjusts to archive benchmarks, and is a sufficient reason for the engineering outline. Joining & Verification

Requirements Management Basic duty is to keep extend inside expenses, inside spending plan, and to address clients issues. Gauge cost of framework in view of necessities. Control the unpredictability of the necessities. Deal with the necessities setup of the framework Negotiate prerequisite changes Re-assess cost of the framework when necessities change.
