Logical, detached and detailed, ISTJs use their experience and store of knowledge, to plan and will work quietly and steadily behind the scenes towards conclusion. The ISTJ has a strong sense of duty, loyalty and tradition and once they are clear on what’s expected, they will work in a methodical way to complete. Risk averse they prefer the known, and prefer facts to concepts.
ISFJs are quiet, and often understated people-centric doers. Conscientious and hardworking, they are loyal and dedicated to people and organisations, and they take their responsibilities very seriously. They have an incredible store of knowledge and superb memory used to support people and solve problems. Shunning the limelight the ISFJ is often the one who quietly make it all happen.
ISTJs bring a strong sense of planning, agreeing objectives and working steadily towards closure. They have a strong eye for detail and can therefore protect the team from going off in a wrong direction.
The ISFJ will bring order, clarity, organisation and planning. Although not the most vocal member of the team, the ISFJ will make sure the team moves towards a 'known' conclusion in a planned way.
ISTJs will be great at ensuring everyone is clear on what is expected, everyone knows what the plan is and their part in it and ensuring that the plan is enacted, so more task- than people-focused.
ISFJs are more of the behind the scenes operators rather than being a charismatic leader. Yet their incredible memory, their caring and practical nature and planning ability make them good team leaders.
Best managed by clear tasks, ISTJs need plenty of time to fully understand what is expected then let them get on, working with consistent steady energy towards completion, not micro managed.
Ironically, because they prove over and over that they can be relied on for their loyalty, attention to detail and high-quality work they can be taken for granted. Give them clarity and trust, they will deliver.
ISTJs have and incredible eye for detail, focus and a desire to drive for closure. They will want to slowly assimilate information and be sure of their facts before moving forward and this will be as per the plan.
The ISFJ is painstaking, orderly, conscientious and anxious with a superb capacity for follow-through although they have a tendency to worry about the smaller things and a reluctance to ‘let go.’
ISTJs are more factual than creative and their value is exactly that: ensuring that was has been agreed is delivered exactly as agreed and translating everything into a plan that is clear and can be delivered.
ISFJs have a great memory for facts and superb attention to detail. They will be more factual and practical than overtly creative, motivated by an internal anxiety to ensure the team doesn’t fail.

ISTJs prefer to keep themselves to themselves and so in conflict situations they will struggle with overt conflict, ie with someone who wants to engage verbally. They are fine with more formal conflict.
The ISFJ will initially close down on conflict as they prefer harmony and indeed will work hard at creating that. Indeed the ISFJ will be a superb diffuser of conflict but they themselves do not enjoy it.
ISTJs have a strong sense of right and wrong and this tends to be around what has been agreed. They believe if you have said you’ll do something then it is akin to a contract and you should fulfil that
ISFJs are often called ‘the defender’ and this is because they will stand up for what is right and the rights of others. So whilst they may shun conflict personally, they will fight for other people.
Formal processes such as writing letters of complaint or going through the proper channels plays to ISTJ strengths. They are measured and formal and so will be very factual and non-emotional.
Naturally more quiet and low key, the ISFJ will be conciliatory and seek consensus preferring to see good in people and they will look to get to a resolution that makes everyone happy.
It is all about right and wrong. ISTJs do not like conflict if it involves emotion, as they prefer to see things far more factually and in a binary way. For them it will be about did it play out fairly and as agreed?
Altercations and over interaction in general sucks the energy of the ISFJ and so they will need some private ‘me’ time to recharge their batteries and build up their energy levels.
Understanding ISTJs pressure points will help you adapt to one another. We all ‘get’ people who are like us, but for a team to work to its optimum level, we need people who are not like us, so the whole is far greater than the sum of the parts. Map your team and get them collaborating.
ISFJs deal with conflict in their unique way. Getting team members to understand the differences, where the potential areas of conflict might be and, more importantly, showing them how they can quickly overcome them is key to team success. Map your team and get them collaborating.
Because of their intense focus ISTJs may be seen as slightly detached, cold and impersonal, possibly even as uncaring. This is not deliberate but it can alienate those trying to get close or get to know them.
ISFJs are deep and caring with strong values and these will be held privately until the ISFJ allows people in. What others will perceive is a helpful, supportive, patient and detailed individual who is under the radar. The ISFJ is sociable but doesn’t like the spontaneity of crowds.
Detached and factual ISTJs often find it difficult to deal with emotions as they see this as irrational and when others display emotions they have to translate the emotion into factual language that they can understand.
The ISFJ is an emotional type, but may struggle at times to deal with these, as they are so private and reflective. It may be possible to deeply offend an ISFJ and not realise it, so private are they.
Deep and private ISTJs will tend to keep their feelings to themselves and until they have the measure of people will be unlikely to proactively share their feelings. Too much interaction sucks their energies.
Once allowed close the ISFJ will open up but it will take time and they are not naturally forthcoming. This may mean it emerges in small chunks, often off the back of other conversations.
ISTJs like people to stick to agreements and commitments and may not understand that this is human nature, not human deficiency as they themselves take such commitments incredibly seriously.
ISFJs have a strong sense of what is right and wrong and will tend to do what they believe is right, even at the expense of themselves. They really do want to support, care and are generous with their time.
