How innovative offerings gain acceptance within market segments How innovative offerings gain acceptance within market segments Solution In the face of cut-throat competition in today’s world, producers are expected to stay ahead if each other but offering something new to the customers. This requires constant innovation offerings that make way into the market through two ways: Diffusion and Adoption. The innovation in a product or service can be very small, or very large so as to change the structure of the whole product or service. After the innovation has been done, two factors play an important role: (i) Diffusion: This deals with the question of whether at all the innovated offering (product/service) would be accepted by the market segment (ii) Adoption: If the answer to ‘diffusion’ is ‘yes’ then this deals with how fast the innovative product or service offering would be accepted into the market segment. Diffusion is seen from a macro point of view wherein focus is put on creating awareness about the new product/service offering so that it gets accepted in the market segment. It is the process by which an innovative offering either is absorbed into the market or is not accepted in the market segment. This process is carried out mainly through communication by mass media, sales persons, word-of-mouth advertisement, etc. There is a target market that needs to be addressed within a specific period of time. Typically there are 4 elements of diffusion: Adoption on the other hand is seen from a micro point of view wherein stress is put on the various stages that a potential consumer goes through while accepting or rejecting the innovative offering, after is has been introduced in the market segment. Sometimes it may so happen that an innovative offering was there in the market but the consumer was unaware of it. This is where advertisement and selling strategies play extremely important roles. There are 5 factors that influence adoption: Thus, the above two processes are the ways through which innovative offerings gain acceptance within market segments..

How does an organization socialize an individual? How ATM(automated teller machine) has changed since its introduction into marketplace. ? Solution Answer:- Socialization can be described as the process through which employees become acclimated to the culture or the norms of the organization. An organization can socialize an individual through informal interactions with the management of the organization, where they can be able to learn the norms and the culture of an organization. Secondly, it can be achievable through peer interactions, where they can be accustomed to the way of doing things in the workplace. Thirdly. this is achievable through giving individuals a sense of membership, where they will feel more valued and able to interact freely with other people. Socializing an individual can also be achievable through involving them in the decision making processes. Over the years, the ATM has evolved through innovation and technology. Firstly, it has changed with regards to its usability. For instance, in the 1980\'s, there was the introduction of the FDK buttons, as well as the color displays. Secondly, intelligent deposit ATM\'s have been introduced to ensure more effectiveness and efficiency(Yang & Ching, 2010). Through the 1990\'s, functionality has also been enhanced. This is in terms of audio input, thermal receipt printers, as well as signature capture of the customers becoming more useful.More recently, the ATM cards have been linked to the mobile phones of the customers, where customers can receive a code through their phone when withdrawing cash from their banks using ATM cards..

Homework: Develop a strategylies) to get a house. Consider possible hypothetic conditions and situations that can be present in the development of the strategy. Make your suppositions of what is feasible and reasonable. MISSION AND VISION OBJECTIVE(S) STRENGTHS 2. 4 Key Success Factor (KSF) 1. 2. WEAKNESSES 2. 3. 4. OPPORTUNITIES 2. 4 S. O. STRATEGIES W.O. STRATEGIES THREATS 2. 4 S. T. STRATEGIES W. T. STRATEGIES Solution It has been mentioned in the question that the strategy is to buy a house and one has to list down the ‘strengths’, ‘weaknesses’, ‘opportunities’ and ‘threats’ in relation to buying a house which implies that a SWOT analysis needs to be done in order to come to the best conclusion. This SWOT analysis is a planning technique strategy which helps to indentify the internal strengths and weaknesses that one might get by buying a house. This helps in judging whether at all the investment is worthy or not. Additionally, there are external opportunities and threats from getting a house, being aware of which will allow the investor to maximize the returns out of the particular investment. Let the investor (may be an individual or a accompany) plan to get a house in area X. The SWOTs can be identified and arranged in a table as follows: Mission and Vision: To invest in a property at competitive prices, that guarantees customer satisfaction with contemporary living styles, in the best housing environment. Key Success Factors: (KSF) Objectives: To buy a house in area X, of a particular size and structure (E.g. 4000 sq. Ft. Duplex villa), in a posh residential complex built the best builders in the market. However, the price would be competitive. Strengths: 1. Area X is developing fast both in terms of residential and business real estate and is projected to be the most sought after area of residence in the city. 2. Investment in area X has gone up tremendously 3. The location of the property is a huge strength, as it is well connected to other parts of the city. Hospitals, shopping complexes, etc are all a stone’s throw away. 4. If the investor were to resale the property at some point, it would be hugely profitable, guaranteeing the highest price of housing in the city in the next few years. Weaknesses: 1. There is a lot of political interference and turmoil in the targeted area of housing. 2. The area is still under development and lacks security for immediate living as the area has reported thefts and burglaries frequently. 3. The roads are in a horrible condition as construction in that area is in full swing. There are a host of residential and commercial properties which are being built there at the same time, which makes staying there immediately a hassle. 4. As of now, there is no police station or hospital nearby. Most of the hospitals, recreation facilities, security facilities etc are ‘projected’ to be completed soon. Therefore, ready-to-move housing will not provide the facilities of a quick doctor on call, or police protect.

Explain in detail the DTE-DCE Transmission? Solution Data communications equipment (DCE) refers to computer hardware devices used to establish, maintain and terminate communication network sessions between a data source and its destination. DCE is connected to the data terminal equipment (DTE) and data transmission circuit (DTC) to convert transmission signals. Data Communications Equipment (DCE) A modem is a typical example of data communications equipment. In general, data communications equipment is used to perform signal exchange, coding and line clocking tasks as a part of intermediate equipment or DTE. Some additional interfacing electronic equipment may also be needed to pair the DTE with a transmission channel or to connect a circuit to the DTE. DCE and DTE are often confused with each other, but these are two different device types that are interlinked with an RS-232 serial line. DTE and DCE connectors are wired differently if a single straight cable is employed. DCE generates internal clock signals, while DTE works with externally provided signals. Without employing a modem, the DCE and DTE can be connected through a crossable cable medium like a null modem for Ethernet or typical RS-232 serial line. Many modems are DCE, while the computer terminal is DTE. The DCE converts the signal to a format appropriate to the transmission medium and introduces it onto the network link. A DCE takes data generated by a DTE, converts them to an appropriate signal, and then introduces the signal onto the communication link. | Commonly used DCEs include modems. To make communication possible, both the sending and receiving DCEs must use the same modulating method (e.g.FSK). Data Terminal Equipment (DTE) DTE includes any unit that functions either as a source of or as a destination for binary digital data. It can be a terminal, computer, printer, fax machine .. Or any other device that generates or consumes digital data. DTE do not often communicate directly with another one; they generate and consume information but need an intermediary to be able to communicate. Analogy: our brain does when we talk. Brains –DTE, mouth/ear – DCE, air/telephone line –transmission medium. In computer data transmission, DTE (Data Terminal Equipment) is the RS-232C interface that a computer uses to exchange data with a modem or other serial device. Data Terminal Equipment is equipment which acts as source or destinations in digital communication and which is capable of converting information to signals and also reconverting received signals. Pieces of data terminal equipment usually do not communicate between each other, which is usually done by data communications equipment. Common examples of data terminal equipment: printers, routers, application servers etc. Features of Data Terminal Equipment: DTE-DCE INTERFACE Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE) . There 4 basic functional units involved in the communication data: DTE and DCE .

Write a two-page paper describing the project in terms of its scope, time and cost goals. Discuss what went right and wrong on the project. Also, discuss the role of the project manager and project sponsor. You will also discuss if the project was successful or unsuccessful. Search the internet for two interesting articles about software development life cycles or project management life cycle, including agile software development. Also, review the website ww w.aailealliance.ong. What do these sources say about project management? Summarize your findings in a one to two-page paper citing any references. Solution For this assignment, would like to discuss 1 project in details. This project we are going to discuss is from a corporate. Whenever the new partners in a particular geographical region signed up, the welcome kit was to be shipped. Partners signed up with the the multinational and the relevant details were passed to this third organization for preparing and shipping out the relevant welcome kits in that region. Multinational M <---------------->Regional Partners P M-------Backend Processing at Regional Company R----------------P The regional company R performed the backend fulfillment at a regional level to prepare & send out the welcome kit - some Software CDs for development, manuals, etc. Let us call this Organization R where the project was done. Scope: Scope of the project involved reading weekly files from M and creating new orders in the ERP system of R. Time: Time of the project implementation was 2 months. Cost: Cost of the project was 50K USD As the project was for a prestigious organization, it was important for regional company R, however its budget was low and it involved multiple stakeholders that played important role in the success/failure of the project. Time: Out of the 2 months, the user requirement and testing needed more time in this case, as this project could mean different things to the various stakeholders. As a project manager it was important to meet up with customer R and also to connect with customer\'s customer. Multinational M had certain assumptions about the project that were missed initially. There was a limited time to successfully launch the project. It helped getting approvals for the requirements in detail which involved data formats, expected delivery schedules, etc. The testing was key in this project as the input files were received from outside company R. The security protocols for file transfers need to be defined and tested. So there was administration team that had a role in this project. Even though there job was for half a day only, certain approvals were needed from the highest level and for the success of the project it was needed to initiate it well in advance. The 2 weeks were needed for requirements gat.

As a result of total quality management, organizational changes in the way teams function has been a direct impact from TQM. Teamwork removes barriers among individuals, departments, and functions resulting in more empowered and motivated employees. The authors discuss several types of teams in chapter 11. Explain the major types of teams found in organizations today. Solution Answer: The Major types of teams found in organizations today are: 1) Problem solving Team: This team generally consist of 5 to 10 employees within a department who meet in a scheduled time to discuss the ways to improve quality, efficiency and enviroment. Every organization will mostly depend on problem solving teams to help in solving organization problems. In this team, members will share their knowledge, experience on how to improve the systematic working/methods in place. 2) Self-managed Team: This team generally consist of 10-15 employees who take responsibilities of their supervisors. The responsibilities includes but not limited to, Fully self managed teams will select members on their own and assess eachother\'s performance 3. Cross Functional Team: Cross functional teams are effective means of allowing people from different department within an organization to share informations, develop new ideas, solve problems and co-ordinate complex projects. It brings people from different functional experts to better invent design or deliver service. The general goal of using cross functional team include some combination of innovation, speed and quality that come from early coordination among the various specialties 4. Virtual Team: Virtual team use computer technology to tie tighter physically dispersed members in order to achieve a common goal. They allow people to collaborate online, whether they are only a room apart or separated by continents. The three primary factors that differentiate virtual teams from face to face teams are:.

(b) is already in equilibrium (c) exit the cell until equilibrium is reached. -20. Rank the following types of cell signaling from A to C, with A representing the type of signaling in which the signal travels the least distance and C the largest distance 8. Paracrine signaling 9. Contact-dependent signaling 0. Endocrine signaling 1. Which of the following if NOT true? (a) Nucleotides and amino acids can act as extracellular signal molecules (b) some molecules can bind directly to intracellular proteins that bind DNA and regulate signal gene transcription (c) Some signal molecules are transmembrane proteins (d) Dissolved gases such as nitric oxide (NO) can act as signal molecules, but because they cannot interact with proteins they must act by affecting membrane lipids 1-24. Which process in each pair is likely to occur more rapidly in response to an extracellular signal? 2. (a) changes in cell secretion OR (b) increased cell division (a) changes in protein phosphorylation Or (b) changes in protein synthesis 24. (a) changes in mRNA levels OR (b) changes in membrane potential 25. (a) response to acetylcholine OR (b) response to testosterone 26. Which of the following statements is true? (a) Extracellular signal molecules that are hydrophilic must bind to a cell-surface receptor so as target cell to change its behavior. (b) To function, all extracellular signal molecules must be transported by their receptor across the plasma membrane into the cytosol. (c) A cell-surface receptor capable of binding only one type of signal molecule can mediate only one kind of cell response 7. (3) Describe in detail how glucose transport occurs in the gut. Include a diagram that shows the proteins involved, their location, and function. Solution 20. A. Contact dependent signalling. B. Paracrine signalling. C. Endocrine signalling. In contact dependent signalling, signalling occurs due to contact between cells. In endocrine signaling, the signaling molecules (hormones) are secreted by specialized endocrine cells and carried through the circulation to act on target cells at distant body sites. In paracrine signaling, a molecule released by one cell acts on neighboring target cells. 21. C . Some signalling moecules are transmembrane protiens. Transmembrane protiens are not known to act as signaling molecules. Other options are true. 24. Changes in mRNA level or changes in membrane potential. 26. A Extracellullar signalling molecules that are hydrophilic must bind to cell surface receptor so as to signal a target cell to change its behaviour. The neurotransmitters carry signals between neurons or from neurons to other types of target cells (such as muscle cells). They are a diverse group of small hydrophilic molecules including acetylcholine, dopamine, epinephrine (adrenaline), serotonin, histamine, glutamate, glycine, and -am.
