The conflict in our project team were about the choosing of leaders and discussing about the team's project. When determining who is going to be the leader, the whole group members is in a state of confusion, shy and no one wants to stand in at first.

Basically the three of them were using forcing or competing style to handle the situation, it forced the whole team to acknowledge them when we are still uncertain (Heldman 2004, p. 292).

Although these may be inaccurate, they may well significantly influence whether the individuals want to progress the relationship to a further stage. For romantic relationships physical impressions of appearance, dress, smell and so on are often important (for women too). General pleasantness is also important for social and business relationships. Experimentation If the parties show initial interested, they may next start exploring, looking for common interests, common acquaintances and other ground on which they can meet and share. In business relationships, there will also be investigation into what each person brings to the table that will add value to the business of the other person.

Case Study- 5 Stages

...Case Study-Week 3 There are five stages to group development. Many groups are unable to make it to the final stage and find it uncomfortable to work within the group they are in. Also they find it almost impossible to finish the tasks that are expected of them. The five stages are as follows: I. Forming stage- this is the initial stage. The primary concern is the entry of the members of the group. Multiple questions are asked as the members within the group begin to identify with other members and the group itself. The main purpose in this stage is getting to know each other, determining the tasks at hand, defining the group rules, and considering the acceptable behavior within the group. II. Storming stage- The is a period of high emotion and tension within the group and among the members. Hostility and fighting between members may occur and the group may experience changes. Coalitions and Cliques may form within the groups. Outside demands may create tension and pressure. Expectations tend to be clarified and the attention gradually shifts to obstacles standing in the way of the group goals. Group members start to understand one another and efforts are made to accomplish group goals and satisfy individual needs. III. Norming stage- this is the initial integration of the group. The point where the group really begins to come together as a unit. There is a new sense of harmony after the storming stage and members try and maintain a positive......

Freud's Psychsexual Stages

...The Psychosexual Stages define how human personality develops from birth to early adulthood. Freud believed that children experience unconscious sexual fixations as they grow in age. These sexual urges change drastically with each stage. Without proper resolution following each stage, we may experience faults in our future personalities according to Freud. In this stage, the first of five, encompassing children from birth to 1, the infant's primary source of interaction occurs through the mouth, so the rooting and sucking reflex is especially important. The mouth is vital for eating and the infant experiences pleasure from oral stimulation through gratifying activities such as tasting and sucking. The mouth is the infant’s primary erogenous zone, meaning that the oral cavity is where libido energy is most focused. The infant gains pleasure through sucking and eating; the child ultimately develops a sense of comfort through oral stimulation. However, the primary conflict at this stage is the weaning process the child eventually must become less dependent on caretakers as it grows. In theory, an infant who is neglected (under-fed) or overprotected (over-fed) may become orally fixated with the onset of adulthood. If fixation occurs at this stage, Freud believed the individual would have issues with dependency or aggression. During the anal stage, the second of Freud’s five stages this begins near the age of 1 and goes till about 3. The erogenous zone shifts from the oral......

Five Stages of Team Development and Virtual Teams

...Describe in detail the five stages of team/group development. Give specific examples for each stage. Explain how and why teams and groups may or may not proceed through these stages. The five-stage model, which can be applied to groups and teams, assumes that members will progress through five phases: forming, storming, norming, performing, and adjourning. Teams and groups do not move through each phase in a sequential pattern, but the model as a whole proves beneficial to individuals who have struggles about working with others. Within this model, individuals shift from independent input to equal effort when working with others (Langton, Robbins and Judge 161). Group development begins with the forming stage. Beginning in the first meeting, this stage is the period where members experience anxiety and uncertainty about the team’s purpose, structure, and guidance (Langton, Robbins and Judge 161). Individual issues include members questioning where they fit in, and group issues include members questioning why the group was formed (Langton, Robbins and Judge 162). Active forming occurs when members doubt their acceptance or belonging within the group, have low trust in others, and make an attempt to understand what is expected of them (Stuermer). The forming stage is complete when members view themselves involved with the team or group (Langton, Robbins and Judge 161); this means members acknowledge the team’s needs over individual ones. The second stage is storming which......

All through the middle childhood weight gain and height is at a steady increase.

Five Stages of Group Development- Organizational Behavior

...Question #1 The five stages of group development; forming, storming, norming, performing, and adjourning are all critical if a group is going to perform at its best. The first stage, forming, is when the group is created. This is the part in the process where the group is either assigned or the group members voluntarily come together as a group. The second stage, storming is when the group member begin to figure out all of the individual team members characteristics and traits. The third stage, norming is where all of the members get familiar with what each member brings to the table. They get to know each other and begin to see what type of skills, strengths, and weaknesses each team member has. At this point in the group development processes all of the team members are getting familiar with each other and their work habits. In the forth stage of the group development process, performing, is where the group works together to accomplish their goal. At this point all group members know each other’s strengths and weaknesses and divvy up the group tasks so that the task is assigned to the group member with the corresponding skills to complete it best. After the group’s goal is performed they then move on to the fifth step in the process, adjourning. This is where the group members wrap up any remaining responsibilities such as deciding if they will meet again for another project. This is the last stage the group will complete.

Stage Craft Essay

...Essay Since ancient times, people have been enjoying the delights of theatre and play enacted and carried out on stage. The history on lighting for the theatre is very interesting and innovative. As technology has developed over the years, theatergoers have been witness to extraordinary progress as innovations took over and added unique contributions to stage craft, architecture and theatrical lighting. The history of stage lighting and lighting cues in theatre dates back to Greek and Roman times. Light has always been an important component for theatrical storytelling, and various lighting techniques have evolved over the centuries, Before the 20th century, many experimented with electric lights but it was until the turn of the century where electric lights were used exclusively in most theatres. During the 20th century, stage lighting design became an art in its own right, emerging from the obscurity of props, set designs, and costumes. Great efforts were to bring the subtlety and drama of effective light on the stage. The American playwright and producer David Belasco and his assistant Louis Hartman had developed many light instruments. Jean Rosenthal, another pioneer of American stage lighting, invented a system for recording a particular lighting sequence so that it could be faithfully repeated. Going into the 1940s and 1950s, stage lighting kept on evolving and improving. Many technical advances included special lenses, reflectors, projectors, and new......

Psychology Stages

...I. PERSONALITY DEVELOPMENT: THEORIES A. Piaget’s Four Stages of Cognitive Development * Sensorimotor stage (Birth to 2 years old). The infant builds an understanding of himself or herself and reality (and how things work) through interactions with the environment. It is able to differentiate between itself and other objects. Learning takes place via assimilation (the organization of information and absorbing it into existing schema) and accommodation (when an object cannot be assimilated and the schemata have to be modified to include the object. * Preoperational stage (ages 2 to 4). The child is not yet able to conceptualize abstractly and needs concrete physical situations. Objects are classified in simple ways, especially by important features. * Concrete operations (ages 7 to 11). As physical experience accumulates, accommodation is increased. The child begins to think abstractly and conceptualize, creating logical structures that explain his or her physical experiences. * Formal operations (beginning at ages 11 to 15). Cognition reaches its final form. By this stage, the person no longer requires concrete objects to make rational judgments. He or she is capable of deductive and hypothetical reasoning. His or her ability for abstract thinking is very similar to an adult. B.
