Executive SummaryThis paper will be providing a self-reflection analysis using marketing management tools mastered during the Marketing for Managers Course. Through self-analysis, I gained an understood of tracking personal brand growth with the use of marketing tools. Such tools are SWOT and TWOS analysis, anchor points, SMART goals action plan, perceptual mapping, and action timeline. The paper also describes examples and essential insights to enable me to reinforce my brand reasoning.
1.0 REFLECTION AND PERSONAL BRANDINGThis paper will be describing my personality evaluation, personal brand development and presentation, and strategic tools application to my brand and career prospects.
1.1 My Personality EvaluationTowards the end of last year, I was lucky to be selected by our school administration to attend to The Brand Marketing Summit in Sydney, Australia. The specific things that were discussed in the summit were customer insights, personal branding, social media marketing, and content marketing. During the conference, several sessions were lined up with the speakers being professionals in marketing management. The speaker for personal branding talked about the practical skills needed for building a personal brand to better market oneself both nationally and globally. The conference provided me more significant insights when it comes to personal branding. That is personal branding cohesiveness, clarity, consistency, and having aims of serving specific customers in the market are crucial in building a strong personal brand. That personal branding is the process of building and maintaining impression and reputation in the market among customers. How your customers view you in terms of your offerings will make your brand in the market. Building a personal brand needs one’s ability to create content and make stories about your market offerings. Providing content and storytelling to customers, market analysts, and marketing professionals is what has always been an uphill task for me since I’m not a person of content and storytelling. It made me worry about my career in marketing management, and I would always ask myself when I will be able to build my brand. I’m a person who likes describing something briefly as well as I need brief replies. That if someone asks me about what business I’m doing in town, I will just reply to them that I’m selling groceries in the downtown store, and that’s all. But when it comes to building a personal brand, that is not the best way to reply. When it is about marketing my brand, I’m supposed to go further and tell stories or provide additional content about what business I’m doing in town. By replying that I’m selling fresh and free delivery groceries in the downtown store, customers can make online orders over my company website or social media platforms.
Have you noticed any differences between the two replies? Yes. The second reply will without a doubt market or build your brand, but the first one won’t at all. It consumes a lot of time. Right? Yes, it wastes time telling stories, but it is worth it because it is the only way of building your brand and marketing yourself better. That proved to be a challenge to me, but I promised myself I have to do it to develop and market my brand better. The speaker also talked about anchor points that make them who they are and what they stand for, for example, having flexible and enough time with their family tells more about who they are, and that is all about personal brand.
The first and foremost thing after the conference was to identify what my passions are and what is all about them. Secondly, with those passions, I possess how I can anchor them to resonate with my personality, and then lastly, how will I convey them to the public or a given market segment in a better manner. My past experiences provided me a glimpse of my passions and strengths. I realized that I have a strong passion for online marketing. My strength was that I was able to communicate clearly and socialize well with the customers through my social media platforms. I was able to sell more groceries to customers over the internet. Knowing my passions is not enough to build my brand, I had to find ways of including my past experiences and strengths to my brand. However, it was difficult for me to do so, but I had to make it happen. I had to create my SWOT analysis as well as TOWS analysis to analyze my brand better. According to Saldanha (2019), to better understand your personality and skills you possess, your SWOT and TOWS analysis comes in handy, and I did that precisely.
My SWOT analysis is provided next.

1.2 Personal Brand Development and Presentation
After conducting my personality evaluation together with analysis of SWOT and TOWS, I now have identified anchor points that can build and sell my brand that is shaping my brand. Those points can show what I stand for and who I include family, community building, leadership, marketing, and business development. In this case, leadership stands in for both organizational and self-leadership that demonstrate my personality, professional (marketing) values, and my family. Having a good time and being flexible to my family, especially my kids, tell me much about my personality. In the case of community building or voluntary activities such as community clean up exercise, tree planting, and various community or optional action plans will show my brand. In the case of marketing and business development, it entails upholding professional values to sell my brand.
Having identified my anchor points that shape my brand, I had to rework my professional goals to develop a better personal brand. I will provide more details in table 3, figure 1, and table 4. My first step in reworking my professional goals was to amend my Twitter page. Amending my Twitter page will help me put my current anchor points to my Twitter page. It will help me expand my professional network since other professionals will be attracted to my new well-updated Twitter page. It will also save time as I will stay focused on pursuing my passions.
1.3 Strategic Tools Application to My Brand
According to Saldanah (2019), to define a personal brand, the SMART goals action plan helps achieve both existing and future professional objectives. A perceptual mapping and action timeline will further reinforce my SMART goals action plan.

According to Saldanha (2019), the Y and X-axis show fundamental anchor points: marketing and leadership/management.
Having done perceptual mapping, I created an action timeline table to better track my SMART goals action plan. The action timeline visually shows and tracks my professional goals to ensure they are on track.

2.0 Conclusion
Having provided a careful and thoughtful self-reflection, having conducted personal analysis by SWOT and TOWS analysis, and having mentioned my anchor points that shape my brand, I feel now I can work towards my career objectives professionally. Additionally, the reflective essay has provided me insights on how to map out both current, short-term, mid-term, and long-term goals action plan. Through this paper, I have known my opportunities and possible future threats that can jeopardize my brand.

The research question played crucial roles in directing and controlling the research and drafting of the report. Specifically, the research question restricted and directed the research and writing of the document through specific ways that entail the determination of suitable search terminologies and selection of the most relevant details to be included in the report. Since the research study was trying to elaborate on how pet food companies thrive from the humanization of pets, I had to make vital decisions on the most relevant details about Blue Buffalo to include in the report. For instance, I had to find out Blue Buffalo’s current and projected revenues as well as its vision and operating strategy, whether it focuses on generating quality products to encourage the humanization of pets. Besides, I had to determine essential details about Blue Buffalo to be included as background information.
Identifying the most suitable pet food company served as the most challenging part of researching and drafting this report. I had to peruse through various pet food firms in an attempt to determine the one with adequate information on matters about the increasing value of pets.
I received lots of valuable suggestions that facilitated a better development and presentation of the report from my instructor and peers. Accordingly, I made some changes that entail the inclusion of additional images and information, as well as the reduction of redundancy and the removal of some unnecessary details. Specifically, I made all the changes suggested by my instructor. Even so, I could not effect all the suggestions from my peers since some of them could suggest a significant alteration of the research question, something that could attract major changes in the report.
Significant differences in style and grammar exist between the memo and the case study. Precisely, the case study uses detailed descriptive information as it strives to elaborate on a particular point. Besides, the case study tends to flow smoothly from the beginning to the end since all data are related. Also, the case study uses third-person pronouns. Accordingly, I had to determine the most appropriate vocabulary that would fit well into the context and provide empirical details rather than personal opinions. Moreover, I had to write complete sentences that offered detailed information.
Writing a case study has proven to be beneficial to students since I learned some crucial skills that entail the importance of engagement, brevity, proofreading, revision, choice of vocabulary, grammar, and style. Consequently, I would rely on specific arguments and research questions to develop future writing projects properly. Besides, I will endeavor to ensure that my documents flow smoothly from the onset to the end. Moreover, I will determine and utilize the most appropriate vocabulary, depending on the context and type of writing/ project.
