Strength Deployment Inventory

Strength Deployment Inventory

SDI is a tool based on 30 years of research by Elias H Porter into Relationship Awareness Theory. SDI is designed to allow people to understand what really makes people tick. It specifically considers what motivates an individual in two conditions; when things are going well, and when they are not.  Greater awareness and understanding in these situations helps increase behavioural effectiveness building positive relationships and overcoming conflict situations. SDI encourages people to celebrate and work with differences and not against them.


Where you have people, you will usually have conflict and in organisations, conflict amongst teams can bring an organisation to its knees. Conflict within teams impacts on productivity, it de-motivates and it results in good staff leaving the organisation.

Conflict typically occurs when faced in situations which threatens and individuals self worth or value. Conflict is almost like a defence mechanism activated when an individuals motivations or values are opposed.

SDI looks at the way people interact with each other. Based on relationship awareness theory, SDI suggests that all people have inner needs that they seek to satisfy. Sometimes, these needs can be satisfied without the interaction or involvement of other people, but in the vast majority of people, to feel good about themselves, people need to have relationships with other people.

The SDI works on the premise that there are two kinds of conflict: warranted and unwarranted. Warranted conflict is where there is disagreement on the actual end goal or outcome. The area in which the SDI is most effective is when unwarranted conflict occurs. Here, there is shared desire to achieve a common end result but at the same time their difference of opinion is about how the goal or objective is achieved.

Building Team Relationships

In contrast, understanding what motivates an individual, and others around them will allow more effective communication, more efficient collaborative working and ultimately a superior end result.

With most teams, the there is a shared desire to achieve a common goal, and individuals within the team fail to interact effectively when they do not understand there own Motivational Value System, and that of others around them. By understanding and respecting the motivations of the people an individual works with will contribute towards creative solutions and stronger relationships
