About TotalSDI

The SDI is an easy to learn, practical and immediately useful "life inventory" based on Relationship Awareness® theory. Utilised internationally for over 40 years the Strength Deployment Inventory delivers proven benefits, both business and personal, by increasing relating skills and decreasing the conflicts which damage or hold back relationships.

The following are some of the key outcomes and benefits that the SDI has delivered to clients globally over the past 40 years:

  • Improves teamwork,
  • Develops managers & leaders,
  • Supports change management,
  • Drives sales,
  • Improves customer service,

One of the primary strengths of the SDI is how quickly and easily SDI gets people connecting, talking and really understanding each other. Across all levels of an organisation, and in any situation where achieving performance goals depends on people working effectively together, the SDI offers “eye-opening” insights that make it easy to achieve effective and profitable relationships.

More about SDI

People work together more effectively when they better understand their own and others’ strengths. SDI® (Strength Deployment Inventory®) is a self-awareness tool that bridges the gap between motivation and behaviour by providing two integrated personality assessments that measure when things are going well and when in conflict.

Relationship awareness theory™

Relationship Awareness theory underpins SDI. It is a motivational typology that has proven to be very accurate in determining the motivations behind behaviour. The theory itself is founded on four simple, yet profound, premises: 1. Behaviour is driven by motivation to achieve or maintain self-worth 2. Motivation changes in conflict 3. Strengths, when overdone or misapplied, can be perceived as weaknesses and 4. Personal filters influence perceptions of self and of others.

How the Strength Deployment inventory® works

When completing the SDI® the learner responds to 20 statements that look at the following two dimensions:

1. When things are going well (in life, not just at work)
2. When things are not going well (in life, not just at work)

The first dimension of SDI helps people understand their motivations and relating styles.

SDI is non-judgemental - there are no right or wrong answers or ideal scores. Each person’s set of scores will position them in two areas on a unique coloured triangle which is then explained in terms of their Motivational Value System™ and their Conflict Sequence™.

Motivation is important because it remains constant and is therefore a more reliable reference when seeking to understand intentions. Behaviour on the other hand can vary depending on the circumstances and what motives the person is seeking to satisfy.

What makes SDI so easy to complete, remember and apply is that it uses colour and their blends to represent the following 7 Motivational Value Systems. This provides a common language that helps facilitate conversations about interpersonal issues.

Relationship Awareness Theory and the psychometric inventories and other resources which are based on it, was developed by psychologist, clinical therapist, educator, and author Elias H. Porter, Ph.D. who was also a student and colleague of Dr Carl Rodgers, a leading psychologist and author.
