Agenda

1)   Why Shift Left?

2)   The PointZERO vision

3)   Designing the improvement strategy

4)   Putting the vision into reality

5)   Expanding the shift left approach

After 70 years of IT experience…

70% of all IT-projects are not successful

30% - 40% of all IT-work is rework

Shift focus from time & cost to quality & risk

About success

What is “success”? Wikipedia: Achievement of a Goal;

the opposite of Failure

When is your business successful? •  Project ready in time? •  IT Quality meets standards? •  Business value is created? •  Clients are happy!!

Application Lifecycle model

Most people accept “Testing” as a fact of life But often they are not happy about it

This lifecycle shows activities.

These activities can be done

sequentially (e.g. waterfall) or

in parallel (e.g. agile).

Each activity is important, you can’t skip any.

© Sogeti

So we performed a TPI NEXT assessment to assess the test maturity

Conclusion: There’s nothing wrong with testing

The fixing and rework is the real problem!

Client said: “Testing costs too much time & money”

© Sogeti

We introduced: “the fixing-phase”

Now something interesting happened; the stakeholder asked:

“Why do we need a fixing phase”? “Can’t they build it right first time”?

PointZERO® is …

A vision aimed at

increasing business success by

parallel and step-by-step improvement

across the application lifecycle,

to shorten time to market,

avoid and reduce cost,

eliminate risk, and

reach fit for purpose quality.

Three key principles

And remember: Quality can’t be ‘tested in’ at the end

The right quality: no less, no more; Suitable for the intended purpose

Faults should be prevented; Frontload the process with quality measures

People are fallible, faults will occur; Make sure no defect progresses to the next activity in the lifecycle

No faults forward to the next activity

Quality assurance: 3 areas

•  Analytical quality assurance: An information system’s (and its intermediate products’) quality is checked against defined criteria. If the desired values are not met, appropriate actions will be taken (most likely rework).

•  Constructive quality assurance: Includes all methods which provide assistance in constructing error-free software beforehand.

•  Organizational quality assurance: To provide an environment in which quality assurance can be established. Organizational quality assurance includes e.g. a quality management organization, training courses, requirements management and development processes.

Right first time Shift left

To enable “right first time” & “no faults forward”: Shift the quality focus to early lifecycle activities

Frontload the

lifecycle with

quality measures

How to improve - Deming Cycle

© Sogeti

Analyze the “AS-IS”-situation: Quality Optimizing Scan

1.   Determine the participants to get a holistic view of the current situation.

2.   Kick off

3.   Answering the questionnaire

4.   Evaluation of the results

5.   Determination of the “pain” points

6.   Verification of the results

A mountain can’t be moved in one day

Maturing is a long process of small steps forward Thus: Parallel & step-by-step improvement Kaizen: continuous improvement Using the “improvement backlog” Start improving at the “weak spots”

How does the improvement relate to success?

What if we don’t change?

What if we do change?

Quick win / medium / long term

What is the actual improvement?

How will you know if it worked?

Prioritizing improvements

© Sogeti

The improvement backlog

•  3 sheets: –  To do –  In progress –  Done

© Sogeti

Detailed analysis

•  Root Cause Analysis - Deductive method to analyze defects in order to find their source.

•  Failure Mode and Effect Analysis - Inductive method to find possible defect insertion points.

•  Software development improvement models such as CMMI ® or SPICE ®

•  Test process improvement models such as TPI NEXT®

Designing the quality improvement roadmap

Implementing Quality Supervision

•  Constructive and analytic quality assurance methods •  Quality gates •  Risk management •  Knowledge management

When ambitions for change are set high, It takes too much time before the actual savings are realized

Manage expectations

Tip: three improvements in parallel

Long term

If you don’t start now it’ll never get ready

Medium term

Useful improvement with high outcome

Quick win Good feeling with fast progress

Medium term

Quick win Quick win

© Sogeti

The result Reduced effort for the lifecycle as-a-whole and Focus shifted to early lifecycle activities

No more wasting time and money by focusing on Quality & Risk
