process of human change

What is the content of this blog?

The purpose of this blog is to briefly describe the different stages of process that a person goes through in any changes that are expressed in SDPDCA process. Description SDPDCA process is the main objective of the blog.

Why is it good to know the SDPDCA process of change ?

this process a person goes through change and therefore the understanding of this process of change is especially important when working with people. It can be used in different fields of private and professional eg. in motivation (of employees, personal way to happiness), influence (salesrep influence of customers, influence employees to find right solution), conflict (conflict management work team, solving partner conflicts).. . This process can be used as an identification tool eg. if we identify that the individual is in the process of decision-making step(2.DESIRE motivational decision), so it makes no sense to give concrete recommendations out how to do something (3.PLAN), while it is reasonable to give him appropriate information to support their decision-making.

Why believe introduced informations?

SDPDCA is mainly based on selected scientific resources of psychology (especially the needs and motivation), biology(biological process of Changes- introduced later in this blog), neuroscience, change management (and confirmed also with my subjective experiences based on this scientific objective informations).


SDPDCA process changes

For better understanding of change process I will introduce 2 examples which will be discussed at each step of SDPDCA process.
Hint: it is advisable that the reader can choose the specific case where ones wants to achieve change, and analyse it at SDPDCA steps.

The need for change action is initiated by some unmeet biological or psychological needs(stimulus).
Needs can be divided into two basic categories of basic(biological needs eg. eat, drink, breathe, ..) and higher(mental needs eg. need for autonomy, belonging, status, ..). More about the human needs.

This needs(stimulus) may come from:
-inner(come from inside of person): hunger, need for creativity,..
-external(comes outside of person, eg. from another person): eg. someone wants to help us, someone is trying to convince us of something with the intention of satisfying their needs. If outside needs should lead to change it needs to be transformed to inner needs..

1.example(hunger): individual feel hunger because lack of food (biological needs), or because of the activation of mirror neurons (eg. Looking at tasty cake activated meet the needs of hunger, creates desire, despite the fact that in reality we are not hungry).
2.example(personal development and relaxation): a person feels unmet needs for personal development (eg. the lack inspiration for creativity, the search for life meaning. so unmet mental needs), and also feel tired(lack of relax, energy. so unmet basic biological needs)

This phase is different depending on whether it is meeting the mental or biological needs. If biologic needs are unmet it automatically activate desires (these biologic instructions are stored in DNA), if mental needs are unmet then following mental steps are done:

Road direction
Perceived unmet needs can be satisfied in different ways(roads) in different road directions.
2.example: individual feels 2 unmet need which can be satisfied in different ways, for example. the need for personal development can be satisfied by education(studying literature of personal development, intellectual conversations, ..), the need for energy supplementation can be satisfied by relaxing exercise(eg. joga), sleep,.. or both felt needs can be satisfied in single way by travelling with blend of relaxation and socializing.

Consequently, a person sets goals
2.exampe: trip to the selected country (eg. Indonesia)

Individual need to set specific expectations that determine when goals will be met(matrices).
2.example: for indonesia trip I’m happy if I will visit the 5 most interesting destinations, 3 beaches, 3 mountain tracks (anything more positive to exceed expectations).

Working with expectations is very important so I introduce another example:
let’s pretend dinner with partner set on specified time (partners expectations could be delicious dinner at specific time). If you can not keep that dinner time, you call it in advance and announced its half-hour delay, it displease partner(change expectations) but if you give reasonable reasoning so then ones should accept change(changing their expectations) and if you arrive earlier than changed time ones will be happy (surpassed her expectations changed). However, if you want to change dinner just before dinner or if you arrive after the agreed time, in both cases the result is partner disappointment(ie. A breach of expectations).
More detailed expectations are developed in theory expectations. A mismatch of expectations needs can lead to several psychological problems(typically leading into the various forms of anxiety and depression).

Motivation Decision Making
I define motivation as the level of faith power to meet expectations. This step leads to decision-making process (based on emotions and / or rationality) resulting in a level of faith power to motivation(positive motivation) demotivation (negative motivation) amotivation(no motivation).
If ones want to do change it needs to achieve some level of motivation.
The relationship between expectations and motivation:
expectations and motivation interact, for example. Ones can set out the objectives, expectations and after getting more information(finding real difficulty, costs, risks ..) it can decrease(formerly High) motivation. more about motivation in motivation blogs

2.example: Ongoing emotional decision (beautiful mountains and beaches, ..) and rational decision making (for how long, estimate travel/accommodations/meal costs, compare effectivity=benefits/costs …), resulting in a decision to go for trip/ don’t go on trip and power of faith(motivation) for selected choice.

The desire and the satisfaction of biologic needs:
1.example: Ones don’t consciously choose direction of way and particular way for satisfication of biological needs. Because hunger can be satisfied one way that you do not choose but humans have encoded it in the DNA(that way is to satisfy hunger intake of nutrients necessary for cell function ie. Food intake).
And also at the biologic needs no set specific objectives, expectations, motivation. This process is automatically(without our conscious influence) handled(through secretion of relevant hormones) on biologic level.

The activation of mental process of detail planning. How exactly to achieve the specified objectives, expectations and thus meet the needs (ie. The choice of tactics).

1.príkad: eg. order food delivery service, make food …
2.príklad: specific planning changes (setting a specific timetable, transport equipment, estimate costs, book reservation, ..).

implementation of changes (do selected road).Effectiveness of do depends on the resources (knowledge ,experience, talent ..) needed to implement the plan.

1.example: move the person to a refrigerator select and eat some foods
2.example: do the trip


measure the current level of fulfillment of expectations. The rate of fulfillment of expectations and needs provides a measure of happiness or unhappiness.


known scientifically based formula of happiness:

average level of happiness = average mood + which can satisfy myself without risk (ie. be happy with what people have) + result that is achieved despite the risk (ie. Meeting the set expectations) + difference what you expect and what you have(ie. exceed expectations, surprise).

1.example: measure degree of saturation
2.example: measure the extent to which expectations are filled(ie. Number of destination set out, ..)

7.ACT on feedback
according to the findings from the previous step there are
-induced relevant emotions on a biological level.
-reevaluation of expectations, objectives, do


emotions on the neurobiologic level:
Emotions (like happiness, sadness, ..) are on the neurobiological level are represented by level of neurotransmitter and it this hormones are interpreted by brain in a relevant person’s behavior. (More on neurotransmitters and their impact on motivation in neuroscience for understanding human behavior through neuroscience).
Pleasant emotions such as happiness increases levels of neurotransmitters such as dopamine, serotonin, opioids .. discomfort conversely reduce or not flood these hormones (eg. A reduction in serotonin leads to bad mood) or to leave other hormones which lead to discomfort(such. cortisol, noradrenaline, activation of certain parts of the brain)
Feeling of happiness start not in fulfillment of need but in fulfillment of expectation. that claim is proved by research with monkeys. monkey hormone levels were measured. monkey receive meals at regular intervals when monkey saw food carier with food containers (though monkey haven’t satisfy their saturation need), monkeys raised levels of relevant happiness hormones(this reaction can be also easily observed in domestic animals if they are giving food :).


Example 1: satisfy hunger feeling launches flood of relevant hormones in the body, which signals the body to stop eating.
2.príklad: meet the set expectations(destination, ..), or failure to meet expectations which instruct to make some corrective actions.

Biological change process

The above process of change is represented on a biological level:
1.stimulus (felt need)
2.stimulus is registered in the limbic system, which creates an urge
3.urge is captured in the cortex as a conscious desire (here are instructions for change).
4.based on instructions of the Cortex body do change information based on doing, sended to reward center (the limbic system) that sends relevant neurotransmitters (like eg. Dopamine).
6. In cortex, these neurotransmitters captured and interpreted to feelings.

Other processes of change

There are several other change processes eg ADKAR process(famous process from change management) that is in comply with SDPDCA process, the main difference is that SDPDCA process have detailed description of Desire phase. ADKAR is designed by Prosci Institute. ADKAR process consists of phases:
(Awareness) Understanding the need for change,
(Desire) desire to promote participate in change,
(Knowledge) Knowledge of how to change,
(Ability) capabilities introduce changes
(Reinforce) Keep the change.
