Software Engineering Management

Consistent application of engineering principles and methods to the development of software (intensive) systems

Engineering Principles: Application of systematic (i.e., predictable, repeatable, scalable) procedures - with well-defined goals (e.g., quality, functionality/scope, cost, time) - with well-defined/structured products, processes, and organization Adherence to existing body of knowledge Observation of constraints (standards, time/cost/quality requirements, etc.) Development and use of models

Planning – deciding what is to be done Organizing – making arrangements Staffing – selecting the right people for the job Directing – giving instructions Monitoring – checking on progress Controlling – taking action to remedy hold-ups Innovating – finding solutions when problems emerge Representing – liaising with clients, users, developers and other stakeholders

Process Taxonomy

H. Dieter Rombach, Martin Verlage, Directions in Software Process Research, Advances in Computers, Volume 41, Marvin V. Zelkowitz (Ed.), Pages 1-63, Academic Press, Boston, MA, 1995.

A Process … … defines Who does What, When

and How to reach a specific goal. In software engineering the goal is

to build a software product or to enhance an existing one

Processes

MTAT.03.243 / Lecture 01 / © Dietmar Pfahl 2015

Plan-Do-Check-Act (PDCA): A systematic approach

to Software Process Improvement (SPI)

• PLAN what you want to accomplish

over a period of time and what you

might do, or need to do, to get there

• DO what you planned to do

• CHECK the results of what you did

to see if the objective was achieved

• ACT on the information –

standardize or plan for further

improvement

MTAT.03.243 / Lecture 01 / © Dietmar Pfahl 2015

Tasks:

• Form groups of two (or three) students

• Read the text below under headline ‘Case

Information’ (5-10 minutes)

• AFTER you have read the text below, put yourself

in the shoes of SI’s process engineer in charge of

planning the intended process change. Recall the

Plan-Do-Check-Act cycle presented in the lecture

and discuss within your group the following

question:

• What activities have to be planned?

• What information/data has to be

gathered/collected?

• In answering these questions, try to be as

detailed as possible. Write down your answers.

Work about 20 minutes on this.

• After 20-25 minutes, we will discuss all groups’

answers jointly in class.

Note: This exercise is a preparation for

Homework 1.

Plan-Do-Check-Act – “Plan”

Where are we today?

How do we get there?

Where do we want to be?

How do we monitor?

How do we check whether we got to where we wanted to get to?

What have we learnt and how do we follow-up?

characterize context identify/list issues (and prioritize)

set goals and measurable targets

define what must be changed and how it must be changed

measure performance get feedback

analyse data compare data with targets

record lessons learnt, best practices update processes, models
