Title: Managing a Portfolio of IT Projects: Corporate and Personal


1
Chapter 10
Its like going out to dinner EVERY night!
  • Managing a Portfolio of IT Projects Corporate
    and Personal

2
Agenda
  • Why Project Management Essential Tension
  • Implementation and Risk
  • The Project Risk Categorization
  • The Portfolio Approach What is a Portfolio?
  • Project Management Approaches 2x2
  • Adaptive Methods

3
The Essential Tension
Discipline (Control)
Agility (Creativity)
4
Problem Statement
  • What tools are at our disposal through which we
    can control project factors that increase the
    risk that implementation of IT will be
    inappropriate, useless, or harmful?

Tools
5
Implementation
IDEA
USE
Needs analysis, feasibility, logical design,
design, coding, testing, integration,
installation, training
Cost/Unit Time
Time
6
Implementation Risk
The probability that returns will not reach
expectation.
Risk is also related to the variance in
perceptions of returns over time the higher the
variance, the higher the risk.
7
What Are We So Worried About?
  • The root of the neurosis stems from the system
    development life cycle

Usage Apply the solution to reduce the problem
Analyze What does the problem look like?
Design What does the solution look like?
Implement Create the solution
If implementation fails, the costs are very
significant
The problem is analyzed to see if there are any
feasible solutions
8
Feasibility
  • There are four components
  • Cost Will the solution cost too much? Can we
    afford any of the possible solutions?
  • Schedule Can the solution be implemented in time
    (so that new problems arent created)?
  • Technology Is there a technological solution
    that actually works (without making new
    problems)?
  • Will Do we have the guts to implement and the
    will to enforce appropriate usage?

9
Three Sources of Risk
  • Size (amount of work)
  • Experience (our expertise)
  • Volatility (definition, stability)

Size influences the amount of workwe have to
dooverall. Less work means less chance for
variability
10
Calculus of Project Risk
  • Risk

Lack of Structure
Technology or Gap

If we can make the technology behave, no problems!

Project Management Approaches 2x2 Tools
The essence of formalization is programming (
control) a surrogate action.
Formalization overcomes lack of control, through
plans and procedures
FORMALIZATIONPLANNING CONTROL
Integration overcomes lack of knowledge through
internal sharing and lack of stability through
external sharing
INTERNAL EXTERNAL INTEGRATION
See Table 10.2 for details
The essence of integration is communication (
sharing) a surrogate for trust.

15
Adaptive Methodologies
  • Adaptive methods are specific to SDLC phases

16
Prototyping
Initial Prototype
Analyst makes improvements
17
Prototyping Risks
What if initial guessis very very wrong ?
What if analyst doesnt listenor hears
incorrectly or is incompetent?
18
Summary of Issues
  • Essential Tensions
  • Management Role
  • Technology Options
  • Complexity
  • Agility, adaptability
  • Role of Knowledge, Communication, Trust
  • Control and Risk
  • Infrastructure, Platformability
