STEP 2: Definition of Terms (10 minutes) Activity: Buzzing (5 minutes) Ask student to pair and buzz in 3 minutes on the following: • What are Theory and Management theories? ALLOW few students to respond WRITE their responses on the flip chart/board CLARIFY and SUMMARISE by using the content below • A theory is a set of ideas expresses certain facts. • Management theories are set ideas referring to management issues occurring to organizations. • The theory of management takes a variety of forms, following are few o Classical management  Deals with the traditional five responsibilities of a manager: planning, organizing, directing, coordinating, and controlling. This is coupled with the science of management, which deals with studying the impact of people and systems on productivity, or output o Behavioral management  Deals with organizational and individual responses to situations. Instead of considering workers as machines and attempting to improve productivity through improving processes, behavioral management looks at environmental, interpersonal, and group interactions and their impacts on productivity. Systems management involves taking a holistic approach to all aspects involved in the process of producing a product or a service. This theory not only looks at processes and human or environmental influences but also focuses on interactions and how they affect the organization o Systems theory of management PST 06101 Leadership and Management NTA L 6 Semester 2 Facilitator Guide 28  Systems theory provides a model in which a manager can understand the interactions among various components of an organization STEP 3: Management Theories (40 minutes) Activity: Small Group Discussion ( 20 minutes) DIVIDE students into small manageable groups ASK students to discuss on the following question • What are the management theories? ALLOW students to discuss for 15 minutes ALLOW few groups to present and the rest to add points not mentioned CLARIFY and SUMMARIZE by using the contents below The following are few selected theories of management Classical theory of management • Henri Fayol believed that management was a process consisting of five different functions. He saw a manager‘s job to include the processes of planning, organizing, directing, coordinating, and controlling. These five functions are part of classical management theory and are at present important components in the daily functions of a manager. o Planning The planning process is designed to help the organization minimize uncertainty in the future. Planning helps determine future success as well as anticipate potential pitfalls o Organizing Organizing is the second function of a manager. It encompasses assigning responsibilities to employees and determining how and when things are to be accomplished. One of the primary organizing functions is to determine the organizational chart. o Directing One of the most important functions of a manager is directing — leading, delegating, and motivating employees to accomplish their jobs. This function relies primarily on the interpersonal skills of a manager because directing involves dealing with people o Controlling The controlling function of a manager is regulatory in nature, by which the manager assures that the functions of the department are progressing in accordance with predefined plans. Behavioral theory of management • Also known as human relations theory, behavioral theory developed as a consequence of the application of the scientific theory. PST 06101 Leadership and Management NTA L 6 Semester 2 Facilitator Guide 29 • In the late 1920s, Elton Mayo conducted individual productivity experiments at the Hawthorne Works plant of the Western Electric Company (Reshef, Elton Mayo & the Human Relations Movement). By varying environmental conditions such as lighting, rest breaks, and lengths of workdays, Mayo attempted to determine which conditions were conducive to the most efficient productivity. Systems theory of management • Systems theory provides a model in which a manager can understand the interactions among various components of an organization. • In contrast to scientific management which analyzes processes by breaking them into smaller parts, systems theory contends that the product of a system is due to the interactions of its parts — if the parts are separated, the system no longer produces the desired output. • Systems theory takes a holistic approach instead of an analytical approach to better understand the factors affecting the desired output. STEP 5: Role of Theories to Managers (30 minutes) • The theories guide managers to organize way of thinking to address organizational challenges example when practicing OPRAS in assigning work and evaluating performance we are applying the theory of peace work to raise institutional productivity through each organizational staff. • Documentation and record keeping when are maintained in offices is the application of Max Weber‘s principle of keeping all office correspondence for future reference. • Trait theory as well guides managers on how to make use staff talents as people differs in

ALLOW few students to respond WRITE their responses on the flip chart/board CLARIFY and SUMMARISE by using the content below • Definition of terms o Management is the process of making things done through people to meet organizational objectives. In that process a number of resources like time, human resource, funds, materials and others will be used. Among of those resources human resource is the master of all or management is the best use of resources to realize result. o A manager is a person who is vested a role of ensuring things are happening as planned and to realize results or meeting organizational goal. Or a manager is a person who makes best use of resources to meet set goals. o Process is a series of events taking place and mainly is ongoing occurrences. STEP 3: Management Concept (40 minutes) • The practice of management is key to the successful performance of professional responsibilities. Managing people, information, and systems allows the creation of an environment suitable to carry out the mission of providing pharmaceutical care. PST 06101 Leadership and Management NTA L 6 Semester 2 Facilitator Guide 23 • Often considered a second-rate subject by pharmacists, management is considered by students to be less important than traditional topics such as pharmacology or pharmacotherapeutics. • However, without the organizational structures and wherewithal of management, it would not be possible to carry out professional duties. Activity: Small Group Discussion ( 30 minutes) DIVIDE students into small manageable groups ASK students to discuss on the following question • What is management concept? ALLOW students to discuss for 15 minutes ALLOW few groups to present and the rest to add points not mentioned CLARIFY and SUMMARIZE by using the contents below • The concept is an organized ideas related to organizational management. It may be of Management theories which as well are divided into old and modern theories. • The old theories are those which tell the foundation of management like Max Weber with Bureaucratic Management and • Modern theories like System Theory of Organization. The modern theories were the improvement of the old ones. Or • Model which represents ideas in a systematic way to lead ending in meaningful message. Example of a management model is Leadership and Management Conceptual Model PST 06101 Leadership and Management NTA L 6 Semester 2 Facilitator Guide 24 Fig. 4.1: Leadership and Management Conceptual Model Management Sciences for Health, 2005 By careful observing the model it shows key functions played by leaders and managers which all ends in improving services to respective organizations. STEP 4: Reasons for Managers to Study Management and Management Theories (20 minutes) Reasons for managers to study management and management theories • Updating managers understanding to management concepts and management theories • Gives them room to merge the theories and working environment • For those who will have time, they may conduct operational research to critique the theories; example Theory X by Mc Gregory advocates that people dislike work if you want them to work they should be controlled and there after reach conclusion. • Generally, the theories guide managers to improve thinking abilities related to institutional challenges. STEP 5: Key Points (05 minutes) • Management is the best use of resources to realize result • a manager is a person who makes best use of resources to meet set goals. • The concept is an organized ideas related to organizational management • Management history started way back during industrial revolution • The theories have both shortcomings and benefits to date. STEP 6: Evaluation (05 minutes) • What is management? • Who is a manager? • What are the shortcomings of old management theories? • What are the benefits of management theories?

STEP 2: Definition of terms (10 minutes) Activity: Buzzing (5 minutes) ASK students to pair up and buzz on the following question for 2 minutes • What is theory? ALLOW few pairs to respond and let other pairs to add on points not mentioned WRITE their response on the flip chart/board CLARIFY and SUMMARIZE by using the content below • A theory is ―a formal statement of rule or ideas which are suggested to explain a fact, event.‖ Or • Is a formal set of ideas that is intended to explain reasons of what makes something happen or exist. STEP 3: Leadership Theories (40 minutes) • Early Leadership Theories/Old Leadership theories o Two early leadership theories are the situational leadership theory and the contingency theory, in which the organizational environment is considered a major factor in leader effectiveness • The situational leadership theory suggests that leaders assume a variety of differ- ent roles depending on the situations with which they are faced. • The contingency theory o Both the situational leadership theory and the contingency theory, involve examining the employee‘s perception of the complexity of the task, which then leads to the relationship the leader must assume; that is, the relationship between the leader and the employee is contingent on the complexity of the task. • Contemporary theories/Modern theories o Two Contemporary leadership theories are the transformational leadership theory and the theory of emotional intelligence o Transformational leadership is a process through which individuals are transformed and changed. PST 06101 Leadership and Management NTA L 6 Semester 2 Facilitator Guide 10 o Emotional intelligence (EI) leadership theory, this concept merits some elucidation as it relates to leadership. Goleman and others describe EI as the ―emotional needs, drives and true values of a person.‖ • Whereas many theories help an individual understand how to lead, there remain styles of leadership that a person can adopt to influence the actions and behaviors of others. Many of the theories discussed earlier describe some form of leadership behavior. The work of Goleman in EI provides a nice framework for describing various leadership styles. Refer students to Handout 2.1: Theories resulting leadership styles. STEP 4: Leadership Styles Derived from Leadership Theories (30 minutes) Activity: Small Group Discussion ( 30 minutes) DIVIDE students into small manageable groups ASK students to discuss on the following question • What are the Leadership Styles? ALLOW students to discuss for 15 minutes ALLOW few groups to present and the rest to add points not mentioned CLARIFY and SUMMARIZE by using the contents below • In Leadership That Gets Results, Goleman (2000) describes the six leadership styles and provides empirical data showing the correlation between leadership style and overall organizational climate. • The data suggest that the authoritative style has the overall most positive effect, with the affiliative, coaching, and democratic styles also positive, with little distinction among these three. • Conversely, the coercive and pacesetting styles have, in the long run, a negative impact on organizational culture and climate. • Goleman cautions that no particular style should be used exclusively, and each has at least a short-term use. Affiliative Style o The affiliative style creates harmony and builds emotional bonds. This style primarily uses the external EIs of social awareness and social skill Authoritative Style PST 06101 Leadership and Management NTA L 6 Semester 2 Facilitator Guide 11 o The authoritative style, although sounding ―bossy,‖ is one of the most positive styles a leader can employ. It is characterized by the self-awareness, social awareness, and social skill Laissez Faire or Free-rein Leadership o Leader leaves it to the subordinates to decide and control them believing that they are competent and motivated. He believes that people will perform better if they are left free to make and enforce their own decision. This style of leadership may be successful where the subordinates are highly competent and fully dedicated to the organization. Bureaucratic Leadership o A bureaucratic leader depends upon rules and regulations developed by him. The rules specify the function and duties of every member of the organization. Such a rule-centered leadership often results in red-tape and inefficiency. Coaching Style o Similar to the authoritative style, the coaching style uses the EIs of self-awareness, social awareness, and social skill. The focus of the coaching style is to help employees improve performance over the long term. Coercive Style o This style is primarily associated with leaders displaying a strong sense of self- management, but focusing little on others. Democratic Style o Democrats are participative consensus developers. They work primarily under the participative management style. Pacesetting Style

Session 38: Waxes 219 Background There is currently an ever-increasing demand for pharmaceutical personnel in Tanzania. This is due to expanding investment in public and private pharmaceutical sector. Shortage of trained pharmaceutical human resource contributes to poor quality of pharmaceutical services and low access to medicines in the country (GIZ, 2012). Through Public-Private-Partnership (PPP) the Pharmacy Council (PC) together with Development Partners (DPs) in Germany and Pharmaceutical Training Institutions (PTIs) worked together to address the shortage of human resource for pharmacy by designing a project named “Supporting Training Institutions for Improved Pharmaceutical Services in Tanzania” in order to improve quality and capacity of PTIs in training, particularly of lower cadre pharmaceutical personnel. The Pharmacy Council formed a Steering committee that conducted a stakeholder’s workshop from18th – 22ndAugust 2014 in Morogoro to initiate the implementation of the project. Key activities in the implementation of this project included carrying out situational analysis, curriculum review and harmonization, development of training manual/facilitators guide, development of assessment plan, training of trainers and supportive supervision. After the curricula were reviewed and harmonized, the process of developing standardised training materials started through Writer’s Workshop approach. The approach included a number of workshops for developing, reviewing, editing and formatting the sessions of the modules. The goals of writer’s workshops were to build capacity of tutors in the development of training materials and to develop high-quality, standardized teaching materials. The training package for pharmacy cadres includes a facilitator guide, assessment plan and practicum. There are 11 modules for NTA level 5 making 11 facilitator guides including one practicum guide. Acknowledgment The development of standardized training materials of a competence-based curriculum for pharmaceutical sciences has been accomplished through involvement of different stakeholders. Special thanks go to the Pharmacy Council for spearheading the harmonization of training materials in the pharmacy after noticing that training institutions in Tanzania were using different curricula and train their students differently. I would also like to extend my gratitude to Christian Social Service Commission (CSSC) for their tireless efforts to mobilize funds from development partners (German Ministry of Industry and action medeor). It is through the implementation of the Multi-Actors Partnership (MAP) project, CSSC has been able to provide the financial and technical support needed during the development of this training material. Many thanks go to the Centre for Educational Development in Health Arusha (CEDHA) experts on health material development and training who coordinated the development of these module sessions particularly Ms. Diana H. Gamuya for her commitment in coordinating and facilitating the planning and development to its completion. Particular acknowledgements are sent to Mr. Dickson Mtalitinya and Members from the secretariat of National Council for Technical Education (NACTE) for facilitating and providing their expertise to the success of this work. It will be unfair if I will not recognize the efforts and contributions of all CEDHA supportive staff that made this process a success; accountant, secretary, drivers and printers Finally, I very much appreciate the contributions of the tutors and content experts representing PTIs, hospitals, and other health training institutions. Their participation in meetings and workshops, and their input in the development of this training manual/facilitators guide have been invaluable.
