Chapter 22 Project Management Slide 9 Risk management
Risk management is concerned with
identifying risks and drawing up plans
to minimize their effect.
Chapter 22 Project Management Slide 10 Risk management (cont’d)
A risk exists when there is a probability
that some adverse circumstance will
• Project risks affect schedule or resources.
• Product risks affect software quality or performance.
• Business risks affect the organization developing
or procuring the software.
(Taxonomy based on Effect)
Chapter 22 Project Management Slide 11 Risk examples
Risk Affects Description
Staff turnover Project Experienced staff will leave the project before
it is finished.
Management change Project There will be a change of organizational
management with different priorities.
Hardware unavailability Project Hardware that is essential for the project will not
be delivered on schedule.
Requirements change Project and product There will be a larger number of changes to the
requirements than anticipated.
Specification delays Project and product Specifications of essential interfaces are not
available on schedule.
Size underestimate Project and product The size of the system has been underestimated.
CASE tool Product CASE tools, which support the project, do not
underperformance perform as anticipated.
Technology change Business The underlying technology on which the system
is built is superseded by new technology.
Product competition Business A competitive product is marketed before the
system is completed.
Chapter 22 Project Management Slide 12 The risk management process
Risk identification – identify project, product and business
Risk analysis – assess the likelihood and consequences of
Risk planning – draw up plans to avoid or minimise the
effects of the risks
Risk monitoring – monitor the risks throughout the project
List of potential
Chapter 22 Project Management Slide 13 Risk identification
May be a team activity or based on the individual
project manager’s experience.
A checklist of common risks types may be used
to identify risks in a project:
• Technology risks
• People risks
Taxonomy based on
• Organizational risks
• Requirements risks
• Estimation risks
Chapter 22 Project Management Slide 14 Examples of risk types
Risk type Possible risks
Technology The database used in the system cannot process as many transactions per
second as expected. (1)
Reusable software components contain defects that mean they cannot be reused
as planned. (2)
People It is impossible to recruit staff with the skills required. (3)
Key staff are ill and unavailable at critical times. (4)
Required training for staff is not available. (5)
Organizational The organization is restructured so that different management is
responsible for the project. (6)
Organizational financial problems force reductions in the project budget. (7)
Tools The code generated by software code generation tools is inefficient. (8)
Software tools cannot work together in an integrated way. (9)
Requirements Changes to requirements that require major design rework are proposed. (10)
Customers fail to understand the impact of requirements changes. (11)
Estimation The time required to develop the software is underestimated. (12)
The rate of defect repair is underestimated. (13)
The size of the software is underestimated. (14)
Chapter 22 Project Management Slide 15 Risk analysis
Assess probability and seriousness of each risk.
Probability may be very low, low, moderate, high,
or very high.
Risk consequences might be catastrophic,
serious, tolerable, or insignificant.
Chapter 22 Project Management Slide 16 Risk types and examples of analysis
Risk Probability Effects
Organizational financial problems force reductions in the Low Catastrophic
project budget (7).
It is impossible to recruit staff with the skills required for the High Catastrophic
Key staff are ill at critical times in the project (4). Moderate Serious
Faults in reusable software components have to be repaired Moderate Serious
before these components are reused. (2).

many transactions per second as expected (1).
Chapter 22 Project Management Slide 17 Risk planning
Develop a strategy to manage each risk...
• Avoidance strategies – reduce the probability.
• Minimization strategies – reduce the impact by
developing contingency plans.
Chapter 22 Project Management Slide 18 Risk management strategies
Organizational Prepare a briefing document for senior management
financial problems showing how the project is making a very important
contribution to the goals of the business and presenting
reasons why cuts to the project budget would not be cost
Recruitment Alert customer to potential difficulties and the possibility of
problems delays; investigate buyingin components.
Staff illness Reorganize team so that there is more overlap of work and
people therefore understand each other’s jobs.
Defective Replace potentially defective components with boughtin
components components of known reliability.
Requirements Derive traceability information to assess requirements
changes change impact; maximize information hiding in the design.
Chapter 22 Project Management Slide 19 Risk monitoring
Regularly assess each identified risk to
determine if it is becoming less or more
Also assess whether the effects of the
risk have changed.
Significant risks should be discussed at
management progress meetings.
Chapter 22 Project Management Slide 20 Risk indicators (warning signs)
Risk type Potential indicators
Technology Late delivery of hardware or support software; many reported
People Poor staff morale; poor relationships amongst team members;
high staff turnover.
Organizational Organizational gossip; lack of action by senior management.
Tools Reluctance by team members to use tools; complaints about
CASE tools; demands for higherpowered workstations.
Requirements Many requirements change requests; customer complaints.
Estimation Failure to meet agreed schedule; failure to clear reported

Chapter 22 Project Management Slide 22 Managing people
People are an organization’s most important
The tasks of a manager are essentially people
Successful management requires a good
understanding of people.
Poor peoplemanagement is an important
contributor to project failure.
Chapter 22 Project Management Slide 23 People management factors
Consistency: treating all team members in an
equitable way without favourites or discrimination.
Respect: recognizing that team members have different
skills and respecting (indeed, capitalizing on) these
Inclusion: developing an environment in which all
views, even those of the most junior staff, are considered.
Honesty: being honest about what is going well and
what is going badly in a project.
Chapter 22 Project Management Slide 24 Motivating people
Involves organizing project tasks and the working
environment to encourage people to work effectively.
Maslow (‘54) suggests that people are motivated by
satisfying their needs...
Maslow’s Needs Hierarchy
Chapter 22 Project Management Slide 25 Needs satisfaction
In software development groups, basic physiological
and safety needs are not (usually) an issue.
• Provide communal facilities
• Allow informal communications (e.g., via social networking)
• Recognition of achievements
• Appropriate rewards
• Training people want to learn more
Chapter 22 Project Management Slide 26 Case study: Individual motivation
Alice is a software project manager working in a company that develops alarm systems.
This company wishes to enter the growing market of assistive technology to help elderly and
disabled people live independently. Alice has been asked to lead a team of 6 developers
than can develop new products based around the company’s alarm technology.
Alice’s assistive technology project starts well. Good working relationships develop within
the team and creative new ideas are developed. The team decides to develop a peerto
peer messaging system using digital televisions linked to the alarm network for
communications. However, some months into the project, Alice notices that Dorothy, a
hardware design expert, starts coming into work late, the quality of her work
deteriorates and, increasingly, that she does not appear to be communicating with
other members of the team.
Alice talks about the problem informally with other team members to try to find out if
Dorothy’s personal circumstances have changed, and if this might be affecting her work.
They don’t know of anything, so Alice decides to talk with Dorothy to try to understand the
Chapter 22 Project Management Slide 27 Case study: Individual motivation (cont’d)
After some initial denials that there is a problem, Dorothy admits that she has lost
interest in the job. She expected that she would be able to develop and use her
hardware interfacing skills. However, because of the product direction that has been
chosen, she has little opportunity for this. Basically, she is working as a C
programmer with other team members.
Although she admits that the work is challenging, she is concerned that she is not
developing her interfacing skills. She is worried that finding a job that involves
hardware interfacing will be difficult after this project. Because she does not want
to upset the team by revealing that she is thinking about the next project, she has
decided that it is best to minimize conversation with them.
Chapter 22 Project Management Slide 28 Personality types
Maslow’s needs hierarchy is almost certainly an
oversimplification of what drives motivation...
One should also take into account different
Chapter 22 Project Management Slide 29 Personality types (cont’d)
• The motivation for doing the work is the work itself.
• The work is a means to an end, which is the achieve
ment of individual goals e.g., to get rich, to play
tennis, to travel.
• The principal motivation is the presence and actions
Chapter 22 Project Management Slide 30 Motivation balance
Most people have personalities that are a blend
of these types, with one usually being dominant
at any given time.
The balance can change depending on personal
circumstances and external events.
Just being part of a cohesive group or team can
be highly motivating to people...
Chapter 22 Project Management Slide 31 Topics covered
Chapter 22 Project Management Slide 32 Teamwork
Most software engineering is a group activity.
A good group is cohesive and has team spirit. The
people involved are motivated by the success of
the group as well as by their own personal goals.
Effective and efficient group communication is a
key determinant of group performance.
Flexibility in composing groups is often limited –
managers must do the best they can with the
Chapter 22 Project Management Slide 33 Advantages of group cohesiveness
Quality standards can be developed by the group
members (and are therefore likely to be observed).
Team members learn from each other and get to know
each other’s work.
Knowledge is shared, so continuity can be maintained if
a group member leaves.
Refactoring and continual improvement is encouraged.
Members work collectively to deliver high quality
results, regardless of who originally created the design
Chapter 22 Project Management Slide 34 Case study: Team spirit
Alice, an experienced project manager, understands the importance of creating a
cohesive group. As they are developing a new product, she takes the opportunity of
involving all group members in the product specification and design by getting them to
discuss possible technology with elderly members of their families. She also encourages
them to bring these family members to meet other members of the development group.
Alice also arranges monthly lunches for everyone in the group. These lunches are an
opportunity for all team members to meet informally, talk around issues of concern, and
get to know each other. At the lunch, Alice tells the group what she knows about
organizational news, policies, strategies, and so forth. Each team member then briefly
summarizes what they have been doing and the group discusses a general topic, such as
new product ideas from elderly relatives.
Every few months, Alice organizes an ‘away day’ for the group where the team
spends two days on ‘technology updating’. Each team member prepares an update
on a relevant technology and presents it to the group. This is an offsite meeting in a
good hotel and plenty of time is scheduled for discussion and social interaction.
Chapter 22 Project Management Slide 35 Team effectiveness factors
The people in the group: You need a mix of people in a
project group as software development involves diverse
activities such as negotiating with clients, programming,
testing, documentation, etc.
The group organization: A group should be organized so
that individuals can contribute to the best of their abilities
and tasks can be completed as expected.
Technical and managerial communications: Good
communications between group members, and between the
software engineering team and other project stakeholders, is
Chapter 22 Project Management Slide 36 Assembling a team
It may not be possible to appoint the ideal people to
work on a project.
• Project budget may not allow for the use of highlypaid
• Staff with the appropriate experience may not be
• An organization may wish to develop employee skills (=
train those who lack skills) on a software project.
Managers have to work within these constraints,
especially when there are shortages of trained staff.
Chapter 22 Project Management Slide 37 Group composition
Groups composed of members who all share the
same motivation can be problematic...
• Taskoriented everyone wants to do their own thing;
• Selforiented everyone wants to be the boss;
• Interactionoriented too much chatting, not enough work.
An effective group has a balance of all types.
This can be difficult to achieve as software engineers
are often taskoriented.
Interactionoriented people are very important as they
can detect and defuse tensions that arise.
Chapter 22 Project Management Slide 38 Case study: Group composition
In creating a group for assistive technology development, Alice is aware of the
importance of selecting members with complementary personalities. When
interviewing potential group members, she tried to assess whether they were task
oriented, selforiented, or interactionoriented. She felt that she was primarily a self
oriented type because she considered the project to be a way of getting noticed by
senior management and possibly promoted. She therefore looked for one or perhaps
two interactionoriented personalities, with taskoriented individuals to complete
the team. The final assessment that she arrived at was:
Chapter 22 Project Management Slide 39 Group organization
The way that a group is organized affects:
• the decisions that are made,
• the ways that information is exchanged, and
• the interactions between the development group and
Key organizational questions to consider include:
• Should the project manager be the technical leader of
• Who will be involved in making critical technical
decisions, and how will these be made
Chapter 22 Project Management Slide 40 Group organization (cont’d)
Key questions (cont’d):
• How will interactions with external stakeholders and
senior company management be handled
• How can groups integrate people who are not co
• How can knowledge be shared across the group
Chapter 22 Project Management Slide 41 Group organization (cont’d)
Small software engineering groups are usually
organized informally, without a rigid structure.
For large projects, there may be a hierarchical
structure where different groups are responsible
for different subprojects.
Agile development is always based around an
informal group on the principle that formal
structure inhibits information exchange.
Chapter 22 Project Management Slide 42 Informal groups
The group acts as a whole and comes to a
consensus on decisions affecting the system.
The group leader serves as the external interface of
the group but does not allocate specific work items.
Rather, work is discussed by the group as a whole
and tasks are allocated (by mutual consent)
according to ability and experience.
This approach is successful for groups where all
members are experienced and competent.
Chapter 22 Project Management Slide 43 Group communications
Good communications are essential for effective
Information must be exchanged on the status of
work, design decisions, and changes to previous
Good communications also strengthens group
cohesion as it promotes understanding.
Chapter 22 Project Management Slide 44 Group communications are influenced by:
Group size: The larger the group, the harder it is for people to
communicate with other group members.
Group structure: Communication is better in informally
structured groups than in hierarchically structured groups.
(But size matters here...)
Group composition: Communication is better when there are
different personality types in a group and when groups are
mixed rather than single sex.
Physical work environment: The organization of the
workplace can help encourage communications.
Available communication channels: Different forms of
communication are supported by a range of technologies.
Chapter 22 Project Management Slide 45 Communication/coordination over
head: The “Mythical ManMonth”
Unfortunately, the time required to complete a SE
project is generally not inversely proportional to
the number of people working on the project.
Adding people to a late project can make it later
(due to communication/coordination overhead).
(F. Brooks, The Mythical ManMonth)
Chapter 22 Project Management Slide 46 The problem with "ManMonths"
PEOPLE Key points
Good project management is essential if software
engineering projects are to be developed on
schedule and within budget.
Software management is distinct from other
• Software is intangible.
• Projects may be novel or innovative with no body of
experience to guide their management.
• Software processes are not as mature as traditional
Chapter 22 Project Management Slide 48 Key points (cont’d)
Risk management is now recognized as one of
the most important project management tasks.
It involves identifying and assessing project risks
to determine their probability and severity.
One should develop strategies to both avoid and
reduce the impact of risks.
Chapter 22 Project Management Slide 49 Key points (cont’d)
People are motivated by interaction with other
people, the recognition of management and their
peers, and by being given opportunities for
Ideally, software development groups should be
small and cohesive.
Factors that influence group effectiveness are
its mix of people, its organization and the quality
of communication among its members.
Chapter 22 Project Management Slide 50 Key points (cont’d)
Communication within a group is influenced by
factors such as:
• the status of group members,
• the size of the group,
• the gender composition of the group,
• the personalities within the group, and
• the available communication channels.
