  • The Company Has Not Replied: How to Run a Business Administration Case Study Project in Nigeria (2026)

    The Company Has Not Replied: How to Run a Business Administration Case Study Project in Nigeria (2026)

    Your topic was approved with a company’s name in it. You sent the letter of introduction to the human resources office three weeks ago, you have called twice, and nothing has come back. The defence date has not moved. This is the most common way a business administration project in Nigeria stalls, and it is fixable in a week if you stop waiting for a reply and change what you are asking for.

    Why the company has not replied

    A company has no obligation to help a student, and most letters give it no reason to. The standard departmental letter of introduction says that you are a bona fide student researching the impact of something on the organisation, and asks for cooperation. Read from the other side, that is a request for an unknown amount of staff time, with an unknown output that might name the company, signed by nobody the manager knows. It goes into a tray. The second reason is that the letter reached the wrong desk: human resources can approve a staff questionnaire, but the document you need for a financial topic sits with the accountant, and the interview you need sits with a line manager, and none of them has been asked. The third reason is the word confidential. If your topic touches customers, pricing, credit or staff records, the company cannot say yes even if it wants to, and silence is the polite form of no. Each of these has a different fix, and all three fixes start with a new letter, not a third phone call.

    The access letter that gets a yes

    Write one page, addressed to a named person, and attach the departmental letter behind it rather than sending it alone. The page has five short parts. What you are studying, in one sentence with the variables named. Exactly what you need from the company, itemised: a 15-minute interview with two managers, a questionnaire to staff of one department that takes ten minutes, and the last three years of the published annual report. How long it will take them, added up, in minutes. What you will do with it: the company is anonymised in the bound copy if they prefer, no customer or personal data is collected, and the raw data is destroyed after the defence. What they get back: a two-page summary of findings, which is the only thing in the letter that costs you nothing and changes the answer. Then find a route to the named person. A lecturer who consults for the firm, an alumnus in the branch, a family friend on the staff, the church or mosque contact: in Nigerian organisations the letter that is handed over by someone the manager knows is answered, and the one that arrives by email is not. The guide to what to do when a project topic is rejected puts it as the gatekeeper test, and it applies after approval as much as before.

    What a company will give you, and what it never will

    Source Usually available Who approves Rarely or never available
    Published documents Annual reports and audited financial statements of listed companies, company profile, organisational chart, published policies Nobody: listed companies file results and disclosures with the Nigerian Exchange and most host them on their own investor pages Management accounts, budgets, board papers
    Staff questionnaire A short instrument to one department or branch, distributed through the HR office Human resources manager or branch manager A census of all staff; questions on pay, discipline or grievances
    Interviews Two to five managers or supervisors, 15 to 30 minutes each The managers themselves, after HR is aware Recorded interviews with executives; anything about litigation
    Operational records Aggregated figures the company already reports: sales by month, staff turnover rate, complaint counts The department head who owns the figure Customer lists, credit files, transaction data, anything identifying an individual

    The table decides the design. If your topic needs the right-hand column, change the topic now; nothing on the right will be released to an undergraduate in time, and a panel knows it. If it needs the left-hand column, you can finish, and most business administration topics do: motivation and performance, training and productivity, leadership style and job satisfaction, inventory practice and cost, all of them live in staff responses, manager interviews and published figures.

    Diagnosis: three sources, one research question

    A company-based project is a case study, and the design has a name and a citation your panel expects: Robert K. Yin’s Case Study Research and Applications: Design and Methods, sixth edition, Sage, 2018 in most reference lists, whose second chapter is titled Case Study Research Designs. State that the study adopts a single-case design with the company as the case and the department or branch as the unit of analysis, and that evidence is triangulated from documents, a questionnaire and interviews. Then make the three sources answer the same questions. For a topic on training and employee performance: the annual report gives the training spend and headcount for three years, the staff questionnaire gives perceived training adequacy and self-rated performance on four-point items, and the two interviews give the manager’s account of how training is allocated. Chapter Four presents each research question with all three sources under it, and the discussion says where they agree and where they do not. That convergence is what a case study is marked on; a questionnaire alone with the company’s name on the cover is a survey with a smaller sample.

    Sample sizes follow the usual rules with the company’s own figures as the population. The staff establishment of the department, obtained from HR or the organisational chart, is the N for the sample-size calculation in the guide to writing Chapter Three section by section; the number of interviews and the saturation argument for a small management sample are in the answer to how many respondents a qualitative project needs. Record the interviews on your phone with consent, and use free tools that transcribe and code them without a budget.

    Documents, interviews and a questionnaire answering the same research question: that convergence is what the case study is marked on.

    Ethics, confidentiality and the Data Protection Act

    Three promises in the access letter become three obligations in the project. First, anonymity of the company if it was requested: the bound copy calls it a manufacturing company in Ogun State or a deposit money bank in Lagos, the real name appears only in the letter of introduction on file with the department, and the annual report is cited in a form your supervisor agrees does not identify it. Second, no personal data beyond the questionnaire: no names, staff numbers or phone numbers on the instrument, and the consent statement on its first page. Third, the statute. The Nigeria Data Protection Act 2023 makes whoever determines the purpose and manner of processing a data controller, which for this project is you, and consent is among the recognised lawful bases; the practical steps for a questionnaire under the Act, and the older 2019 regulation that many templates still wrongly cite, are set out in the comparison of Google Forms, KoboToolbox and paper for project data. If the company asks you to sign a non-disclosure form, sign it, keep a copy, and tell your supervisor, because it may restrict what the appendix can contain.

    Writing it up: the two sections a case study adds

    Chapter Three gains a section that a survey project does not have, usually headed Profile of the Organisation or Brief History of the Case Organisation, placed after the research design and before the population. Six to ten sentences: what the company does, when it was established, its size in staff and branches from the annual report, the department studied and why it was chosen. Cite every figure. Chapter Four gains a structure: for each research question, the documentary evidence first, then the questionnaire table, then the interview finding, then two sentences on convergence. The guide to writing Chapter Four covers the tables; the case-study addition is the convergence sentence under each of them. Chapter Five gains one limitation the panel will raise if you do not: a single-case design describes this company and supports analytic, not statistical, generalisation. Write it in those words, then say what a multiple-case study across three firms in the sector could test next. That paragraph turns the design’s weakness into the recommendation for further study.

    If the company still says no in week three

    Keep the topic and change the design. Two switches are accepted in every department. The documentary case study uses only public sources: three to five years of a listed company’s annual reports and disclosures, analysed for the variables in your topic, with ratio analysis or trend tables in Chapter Four and no fieldwork at all; the company cannot refuse what it has already published. The multiple small-firm study replaces one large company with ten to twenty small businesses in a market or industrial cluster you can walk into, where the owner is the gatekeeper and the interview happens the same afternoon. Write a half-page memo to your supervisor stating the access problem, the proposed switch and the unchanged research questions, and ask for a signature on it; that memo is the document that protects you at defence when a panel member asks why the named company disappeared. The three matched objectives, questions and hypotheses stay exactly as approved, in the form shown for a management topic in the worked examples of research questions and hypotheses for a marketing project.

    Where Tesify fits in a company project

    The weeks lost waiting are usually recovered in the writing, and that is where Tesify does its work. Paste the approved topic and the company profile and it drafts the Chapter Three research design paragraph as a single-case study with triangulated sources, the profile of the organisation section from the figures you supply, and the population and sampling paragraphs around the staff establishment you obtained. Paste the questionnaire results and the interview summaries and it drafts Chapter Four in the source-by-source structure under each research question, with the convergence sentences left for you to judge. The automatic bibliography formats Yin, the annual reports and the Act in your department’s style, and the AI editor tightens the prose without changing a figure. The free plan is the starting point and asks for no card; everything above is drafted from your own data, in your own words after editing, which is the only way the project survives a similarity check and a panel.

    Draft the case-study Chapter Three while the letter is out

    Start with the free plan, paste your approved topic and the company profile, and have the research design, the profile of the organisation and the sampling section drafted before the company replies. When the data arrives, Chapter Four follows the same structure.

    Frequently asked questions

    Can I do a final year project on a company that has not given me permission?

    Yes, as a documentary case study using only what the company has published: annual reports, audited statements, disclosures and its own website. Fieldwork inside the company needs its consent; analysis of its public documents does not.

    Should I name the company in my project?

    Name it in the topic submitted to the department and in the letter of introduction. In the bound copy, use the real name only if the company agreed; otherwise describe it generically and tell your supervisor the arrangement.

    How many interviews do I need for a company case study?

    Two to five managers or supervisors is the usual range for an undergraduate single-case study, with the saturation argument stated in Chapter Three, alongside a staff questionnaire and the documents.

    Is a case study on one company acceptable for a business administration project?

    Yes. State it as a single-case design after Yin, name the unit of analysis, triangulate documents, questionnaire and interviews, and write the analytic-generalisation limitation in Chapter Five.

    Does Tesify write the project for me?

    No. It drafts the chapters from the topic, profile and data you paste in, and you edit and defend every sentence. Submitting text you did not shape and cannot explain fails both the similarity check and the defence.

    Will a Tesify draft pass the plagiarism check?

    Drafts are generated from your own inputs, not copied from existing documents, and the passages you cite are your responsibility to quote and reference. Run your department’s similarity check before submission as you would for any draft.

    How much does Tesify cost?

    The free plan is the entry point and needs no card. Paid plan prices are shown on the Tesify site, where local payment options are listed.

    What if the company asks me to sign a confidentiality agreement?

    Sign it, keep a copy, and inform your supervisor at once. It usually means the company is anonymised and raw data stays out of the appendix; it rarely prevents the project.

  • Zones, Counts and Breakpoints: Writing Chapter Four of a Microbiology Project in Nigeria (2026)

    Zones, Counts and Breakpoints: Writing Chapter Four of a Microbiology Project in Nigeria (2026)

    Every Chapter Four guide you have opened assumes a questionnaire: a bio-data table, a four-point mean against 2.50, a chi-square. You have thirty plates, a grid of biochemical reactions and a page of zone diameters in millimetres. The chapter is not harder than the questionnaire version. It is four tables in a fixed order, and each one has a sentence pattern that turns a measurement into a finding.

    What Chapter Four is when your data came off a plate

    A microbiology project produces measurements, not opinions, and the chapter is organised by what was measured rather than by research question alone. Nigerian departments accept the same four-table spine for almost every undergraduate topic in the field, whether you sampled sachet water, ready-to-eat food from a campus canteen, hospital door handles, urine specimens or wound swabs. Table one gives the counts: how much grew, per millilitre or per gram, by sample or by location. Table two gives the identification: the colonial and microscopic appearance and the biochemical reactions that let you name each isolate. Table three gives frequency: how many of each organism, and what percentage of the total that is. Table four gives the antibiotic susceptibility: a zone diameter in millimetres for every isolate against every disc, and beside it the letter that interprets it. A plant extract project replaces table four with zones at graded concentrations plus a minimum inhibitory concentration, but the spine does not change. Write the tables in that order, number them Table 4.1 upward, and give each one a title that names the variable and the source, not the word Results.

    The counts table and the identification grid

    The counts table carries one number per sample with its unit written into the column heading, not into every cell: colony-forming units per millilitre for a liquid, per gram for a solid, per square centimetre for a swabbed surface. Report the dilution factor you multiplied by in the table note, because a panel member will ask, and give the mean of your replicate plates rather than one plate chosen because it counted nicely. If your topic implies a limit, compare against it explicitly and cite the document and its edition: the Standards Organisation of Nigeria publishes a drinking water standard your department will hold a copy of, and a food or water topic that never compares its counts to a stated limit has produced numbers instead of a finding.

    The identification grid is the table students most often build wrongly, because they present it as prose. It is a matrix: isolate codes down the left, and across the top the colonial morphology, Gram reaction, cell shape, then one column per biochemical test you actually ran, and a final column headed Probable organism. Catalase, coagulase, oxidase, indole, citrate, urease, motility, triple sugar iron and the sugar fermentations are the usual set. Fill the cells with plus and minus signs, not sentences, and state in the text below which key you read them against; Bergey’s Manual of Determinative Bacteriology is the reference Nigerian departments expect to see cited for conventional identification, and naming it is what converts a grid of symbols into an identification you can defend. Write probable organism, not confirmed organism, unless you ran a confirmatory method, and say so in Chapter Five as a limitation.

    The susceptibility table, and the standard you read it against

    A zone diameter on its own means nothing. Twenty millimetres is susceptible for one organism and drug pair and resistant for another, and the only thing that makes your table interpretable is a named breakpoint document with its edition. Two exist, and a Nigerian student can use either, but must use one of them consistently and say which in Chapter Three.

    Document What it is Current edition Cost Method it assumes
    CLSI M100 Performance Standards for Antimicrobial Susceptibility Testing, published by the Clinical and Laboratory Standards Institute 36th edition, published 26 January 2026 Purchased from CLSI Valid only if the procedures in CLSI M02 for disk diffusion, M07 for dilution in aerobes and M11 for anaerobes were followed
    EUCAST breakpoint tables Clinical breakpoint tables of the European Committee on Antimicrobial Susceptibility Testing v16.1, valid 24 June 2026 to 31 December 2026 Free to download EUCAST disk diffusion and MIC methodology, with its own dosages document at v16.0 effective 1 January 2026

    CLSI M02, the disk diffusion standard the M100 tables depend on, is in its fourteenth edition, published 19 March 2024. If your laboratory ran Kirby-Bauer on Mueller-Hinton agar and read the zones with a ruler or callipers, you followed a CLSI-shaped method and M100 is the natural table to interpret against; if your department has no current copy, the free EUCAST tables are the honest alternative, and using them is not a weakness provided Chapter Three says the EUCAST methodology was followed rather than silently mixing the two. The commonest single error in a Nigerian microbiology Chapter Four is a susceptibility table interpreted against a breakpoint document that is never named, or named without an edition or version. Write it in full once, in Chapter Three, and refer to it by name under every susceptibility table thereafter.

    The second commonest error is the letter I. Under EUCAST, since 2019, I no longer means intermediate: the committee redefined it so that a microorganism is categorised as susceptible, increased exposure when there is a high likelihood of therapeutic success because exposure to the agent is increased by adjusting the dosing regimen or by its concentration at the site of infection. If you are using EUCAST tables, write the category out in words the first time and do not gloss it as intermediate anywhere in the chapter. A panel member from a clinical microbiology background will notice, and it is the cheapest correction you will ever make.

    The MAR index: one calculation that upgrades the whole chapter

    If you tested each isolate against a panel of antibiotics, you already hold the data for the multiple antibiotic resistance index, and computing it costs one column. For each isolate, divide the number of antibiotics to which it was resistant by the total number tested. An isolate resistant to six of ten discs has an index of 0.6. The convention comes from Krumperman’s 1983 paper in Applied and Environmental Microbiology, which proposed indexing to identify high-risk sources of faecal contamination and set the threshold above which a source is treated as high risk at 0.2. The reference in APA form is Krumperman, P. H. (1983). Multiple antibiotic resistance indexing of Escherichia coli to identify high-risk sources of fecal contamination of food. Applied and Environmental Microbiology, 46(1), 165 to 170.

    The index earns its place because it converts a wall of letters into one number per isolate that a reader can compare, and because the threshold gives you a claim: isolates above 0.2 came from environments where antibiotics are heavily used, which for a sachet water or street food topic is the whole argument of your Chapter Five. Add the column to your susceptibility table, add a sentence stating how many isolates exceeded the threshold and what proportion of the total that is, and the discussion writes itself. For a project on the antibacterial activity of a plant extract the equivalent upgrade is the pair of endpoints: the minimum inhibitory concentration, the lowest concentration of extract at which no visible growth appeared in the tube or well, and the minimum bactericidal concentration, established by subculturing the clear tubes onto fresh agar and reporting the lowest concentration that produced no growth on the plate. Report both in the same unit, usually milligrams per millilitre, and state the solvent and the negative control, because an extract dissolved in dimethyl sulfoxide needs a solvent-only control before any zone you measured belongs to the plant.

    Writing the discussion: three moves under every table

    Nigerian departments differ on whether the discussion sits inside Chapter Four or opens Chapter Five, so follow your own department’s format, but the moves are the same wherever it lives. Move one restates the result in words with the number in it, without repeating the whole table: the highest mean count was recorded in samples from the motor park, at a figure you quote once. Move two compares it with published work, and this is where a microbiology discussion is won or lost, because the comparison must be with studies on the same organism from a comparable setting, and Nigerian journals are where those live. The African Journal of Clinical and Experimental Microbiology and the microbiology titles hosted on African Journals Online carry the isolation-and-susceptibility studies from Nigerian states that your examiner has read; a discussion that compares a Kano sachet water result only with European clinical isolates reads as though the literature search stopped at the first search engine page. Move three explains the difference, in one sentence, with a mechanism rather than a shrug: a higher resistance rate than an earlier study in the same state is attributable to something nameable, and if you cannot name it, say the design cannot separate the possibilities and put that in the limitations. The same discipline in stating findings applies here as anywhere, and the ladder of how strongly you can state a finding is worth reading before you write the word proves.

    Two structural points that panels raise every session. First, every table needs the interpretation paragraph beneath it, and the general architecture of that paragraph is set out in the guide to writing Chapter Four table by table; the microbiology version simply substitutes a count or a zone for a mean. Second, if you ran any inferential test, name it and its assumption: comparing mean counts across three sampling sites is an analysis of variance, and comparing resistance frequency between two sources is a chi-square on counts, never on percentages. The decision table in the guide to choosing a statistical test covers both. Many microbiology projects report only descriptive statistics, which is acceptable when the objectives were framed descriptively, but a project whose objectives promise a comparison and then delivers only percentages will be asked why at the defence, and the inventory of questions panels actually ask lists that one under methodology.

    Carrying it into Chapter Five

    The summary in Chapter Five is built from your table titles, one sentence each, in the order the tables appeared. The conclusion answers each objective in turn: whether the samples were contaminated, which organisms predominated, and what the susceptibility profile means for treatment or for the safety of the product. Recommendations must be addressed to named bodies, which in a microbiology project are usually regulators, hospital infection control committees, vendors or the state ministry of health, not the vague public. The contribution to knowledge is the one your panel examines hardest, and for an isolation-and-susceptibility project it is almost always local and current: a susceptibility profile for a named organism from a named source in a named location at a stated date, which did not exist before you produced it. The structure of the whole chapter is set out in the guide to writing Chapter Five section by section, and the sister case of an engineering project with laboratory rather than survey data is worked through in what goes in Chapter Four when there is no questionnaire.

    Where Tesify fits when the plates are read and the chapter is blank

    The laboratory work is finished and the writing is what is left, which is the part that takes weeks you no longer have. Paste your counts, your identification grid and your zone diameters into Tesify and it drafts the presentation paragraph under each table in the pattern above, the interpretation sentence that names the breakpoint document and the category, and the three-move discussion for each finding with the comparison left open for the Nigerian study you choose to cite. The automatic bibliography formats Krumperman, the standards and the journal articles in your department’s style so the reference list stops being an evening’s work, and the AI editor tightens the prose without touching a figure. The free plan is the entry point and asks for no card. Everything it produces is drafted from the numbers you measured, which is the only version you can stand behind when a panel member points at Table 4.4 and asks how you arrived at that letter.

    Turn your plates and zones into Chapter Four this week

    Start on the free plan, paste your counts, identification grid and susceptibility readings, and get the tables, the interpretation paragraphs and the discussion moves drafted in the order your department expects.

    Frequently asked questions

    What goes in Chapter Four of a microbiology project?

    Four tables in order: colony counts with their units, the isolate identification grid of morphology and biochemical reactions, the frequency and percentage of each organism, and the antibiotic susceptibility table of zone diameters with their interpreted categories. Each table carries an interpretation paragraph beneath it.

    Which breakpoints should I use, CLSI or EUCAST?

    Either, provided you use one consistently and name it with its edition in Chapter Three. CLSI M100 is in its 36th edition, published 26 January 2026, and is purchased; the EUCAST clinical breakpoint tables at v16.1 are free to download and valid to 31 December 2026.

    Does I mean intermediate in a susceptibility table?

    Not under EUCAST. Since 2019 the category means susceptible, increased exposure, defined as a high likelihood of therapeutic success because exposure to the agent is increased by adjusting the dosing regimen or by its concentration at the site of infection. Write it out in words rather than glossing it as intermediate.

    How do I calculate the multiple antibiotic resistance index?

    Divide the number of antibiotics to which an isolate was resistant by the total number tested. An isolate resistant to six of ten discs scores 0.6. Following Krumperman’s 1983 paper, an index above 0.2 marks the sample as coming from a high-risk source.

    Do I need statistical tests in a microbiology project?

    Only if your objectives promise a comparison. Descriptive percentages are acceptable for a purely descriptive objective, but an objective that compares sites or sources needs an analysis of variance on means or a chi-square on counts, never on percentages.

    Can I say I identified an organism if I only ran biochemical tests?

    Write probable organism and name the key you read the reactions against, usually Bergey’s Manual of Determinative Bacteriology. Conventional identification without a confirmatory method belongs in Chapter Five as a stated limitation, which panels accept when it is declared.

    What do I report for a plant extract project?

    Zones of inhibition at each concentration, the minimum inhibitory concentration as the lowest concentration with no visible growth, and the minimum bactericidal concentration from subculturing the clear tubes. State the solvent and include a solvent-only negative control.

    Where do I find Nigerian studies to compare my results with?

    The African Journal of Clinical and Experimental Microbiology and the microbiology titles hosted on African Journals Online carry isolation and susceptibility studies from Nigerian states, which are the comparable settings your examiner expects to see in the discussion.
