The line graph illustrates the trends in customer inquiries received by a Tourist Information Office over a six-month period in 2011, categorised by interaction method: in person, by letter/email, and by telephone.
Across the six-month span, there is a clear divergence in the popularity of inquiry methods. In-person inquiries exhibited a consistent upward trajectory, ultimately surpassing both telephone and written inquiries by June. Conversely, inquiries by letter or email displayed a marked decline, plummeting to their lowest levels in May and June. Telephone inquiries, while initially the most prevalent method, experienced fluctuations before declining in the final months.
In January, telephone inquiries were the dominant method, accounting for 900 inquiries, while in-person inquiries were significantly lower at 450. By February, telephone inquiries decreased to 800, whereas in-person inquiries rose to 600. From March onwards, in-person inquiries demonstrated a steady increase, peaking at 1900 in June. Telephone inquiries peaked in May at 1400 before declining to 1600 in June. Notably, the gap between in-person and telephone inquiries widened significantly in the latter half of the period.
Inquiries by letter or email began at 750 in January and showed a gradual decline, reaching 700 in February and March. A sharper decline occurred in April, with inquiries dropping to 550, and further plummeting to 350 in May and June. This consistent downward trend highlights a clear shift away from traditional written communication in favour of more immediate interaction methods.
