Mobile Evaluation Log ===================== Evaluator: Daniel Scharf Age: 22 Gender: male Device: Samsung Galaxy A51 OS and Version: Android 10 Screen Size: 6.5'' Screen Resolution: 1080x2400 Web Browser and Version: Samsung Internet Browser 20.0.3.10 Ad Blocker and Version: AdGuard 2.7.0 Internet Connection: WiFi Download Speed: 7.8Mpbs Screen Recording Software: Samsung Bildschirmrecorder Recording Resolution: 1080x2400 Planned Date of Evaluation: 2023-04-14 Negative Findings (Problems) ----------------- o DS-Neg01 Title: Ad-Blocker blocks offers and personal recommendations Description: With Ad-Blocker enabled some of the offers and personal recommendations on the website are blocked and appear to be loading forever. These offers are not an extra advertising of a third party, but offers of kastner-oehler themself and because of this, they should not be blocked. The loading signs indicate that something will come but, nothing is going to happen. Video Clip: ds-neg01-block-offers-with-adblocker.mp4 ds-neg01-block-offers-without-adblocker.mp4 Heuristic: A01 Feedback How Reproducible?: Go to the main page of kastner-oehler.at an scroll down a bit. Some of the offers appear to be loading endlessly because the ad-blocker is enabled. One such case for example is above the field for the newsletter subscription on the main page. o DS-Neg02 Title: Two back-to-top buttons with different symbols Description: When scrolling down on the website two buttons appear on the bottom site of the screen. One on the bottom right site which stays even when not touching the screen with an arrow to the top and second smaller one in the middle of the bottom border which only appears when scrolling and has an arrow to the top but this time which a dash above it. During the scrolling process there are two buttons on screen which both do the same thing (jump to the top of the site) but have different symbols. They also don't appear at the same time when you reload the site. Video Clip: ds-neg02-two-back-to-top-buttons.mp4 Heuristic: A04 Consistency How Reproducible?: Go to the main site of kastner-oehler.at an scroll down. After a few scrolls first the button on the right side appears and after a few more scrolls the second one in the middle appears and both have the same usage but different symbols. o DS-Neg03 Title: Filter Options do not load properly every time Description: The website offers a option to filter items in the product catalogue. This "Filtern&Sortieren"- option contains multiple subcategories like sort order, brand, size, etc. from which the user can choose his preferred combination. But sometimes, when opening the filter options, the filters don't load correctly and therefore if you then press on a subcategory, the selected category does not open correctly. If you open the "Filtern&Sortieren"-option and a small symbol appears for a short time which states that the filter options are loaded then everything works. But this symbol does not appear every time and then the filter selection does not work. Video Clip: ds-neg03-filter-dont-load.mp4 Heuristic: How Reproducible?: Main Page -> "Menü" (three strips in the upper left corner) -> "Neu" -> "Damen" -> "Alle Artikel" -> "Filtern&Sortieren"-option: If the loading symbol with "Filter werden geladen" does not appear select "Sortieren" and you will notice that the sort order selection will not open correctly. If the loading symbol appears, select any sort option, press "Ergenisse anzeigen" and then open the "Filtern&Sortieren"-option and try again. o DS-Neg04 Title: Jumping through product lists Description: If you, for example, already found an item which you like but then accidently closed the browser or just though, you will purchase it later and can't remember the name, but you remember the site in the product catalogue you have to scroll down every time to come to the next site button so that you can jump to the desired site in the catalogue. And additionally, it is only possible to jump to the next page and not directly to the desired page. Video Clip: ds-neg04-jumping-through-pages.mp4 Heuristic: A07 Flexibility and Efficiency of Use How Reproducible?: Main page -> "Menü" (three strips in the upper left corner) -> "Herren" -> "Bekleidung" -> "Hemden" -> "Businesshemden" -> You know that the shirt you want is on page 4 of the product catalogue, so you have to scroll down completely three times to jump to the desired page. o DS-Neg05 Title: Wrong error message in registration process Description: In the registration process you are asked to enter your postal code (PLZ) and your city. If you only enter your postal code and leave the city empty and press enter/register, then you get an error message next to the city field which states:"Die von Ihnen eingegebene PLZ ist ungültig. Bitte überprüfen Sie die Eingabe und korrigieren Sie diese.". The system does say something is wrong, but instead of saying the city is missing it says that the postal code is wrong. Video Clip: ds-neg05-wrong-error-city.mp4 Heuristic: A09 Good Error Messages How Reproducible?: Main page -> Login/Registration (Symbol of a person in the upper right corner) -> "Jetzt Registrieren" -> Enter a valid postal code, leave the city field empty and press enter o DS-Neg06 Title: No checks if postal code is valid Description: In the registration process you are asked to but in your postal code and your country, but the system does not check, if the postal code is valid in the selected country. Therefore, it is possible to enter a postal code which does not exist in the selected country. Video Clip: ds-neg06-no-check-postal-code.mp4 Heuristic: A05 Error Prevention How Reproducible?: Main page -> Login/Registration (Symbol of a person in the upper right corner) -> "Jetzt Registrieren" -> For country select "Austria" and as a postal code enter a 4-digit number which starts with 0. The system will accept it although there does not exist a postal code in Austria which starts with a 0. o DS-Neg07 Title: Unnecessary big size selector Description: In the filter options is the option "Grösse" to select the desired size, but instead of one combo box for selection or one text field with auto completion to enter the desired size, there is a large table of buttons with all different sizes. This is especially annoying when you enter a category with not only one type of clothing, because then different size systems are put together in this list of sizes and make it very hard to read, particularly on small devices like mobile phones. Video Clip: ds-neg07-big-size-selector.mp4 Heuristic: A08 Aesthetic and Minimalist Design How Reproducible?: Main Page -> "Menü" (three strips in the upper left corner) -> "Neu" -> "Alle Artikel" -> "Filtern&Sortieren"-option -> "Grösse" o DS-Neg08 Title: Breadcrumbs disappear when refreshing site Description: Breadcrumbs (the list of pages which someone clicked through to come to the current page) are not loaded in correctly when jumping through different looks in the "Styles and Looks"- section. The breadcrumbs disappear and appear when reloading the site and jumping between looks randomly. Video Clip: ds-neg08-breadcrumbs-disappear.mp4 Heuristic: How Reproducible?: Main page -> "Menü" (three strips in the upper left corner) -> "Herren" -> "Looks" -> "New Neutrals" -> Jump between looks ("Vorheriger Look" and "Nächster Look") and watch for changes in the breadcrumbs. Often the last breadcrumb for "New and Neutral" doesn't load at all, then you have to restart the process from the main page. o DS-Neg09 Title: Color changing symbols with different actions Description: When scrolling through the product list, items which are available in more than one colour have a selection of all available colours underneath. These colour-indicators have different actions in different contexts. In the looks category if you click on one of the colours, the preview picture of the clothing item changes colour without opening a new page, but if you click on one colour in a normal product catalog page, the single product page opens with the selected colour. Video Clip: ds-neg09-different-colour-changer.mp4 Heuristic: A04 Consistency How Reproducible?: First go to: Main page -> "Menü" (three strips in the upper left corner) -> "Herren" -> "Bekleidung" -> "Hemden" -> "Businesshemden" -> Scroll down to one shirt, which is available in multiple colours -> Click on one of the different colours, then the single product page opens with the selected colour. On the other hand, go to: Main page -> "Menü" (three strips in the upper left corner) -> "Herren" -> "Looks" -> "New Neutral" -> Scroll down to an item, which is available in multiple colours -> Click the colour, then the preview image changes colour without opening the single product page. o DS-Neg10 Title: Buttons not loading correctly Description: In the product catalogue view, there are further selection possibility for subcategories at the top of the item list. In some subcategories, if there are no further subcategories available, then there is (if currently available) the selection between new and sale items visible. If you select the sale category, only sale items get shown. If you again click on this sale button the side reloads, but during the reloading process the "new"-button gets shown again. This can lead to confusion, because the user is does not know at the beginning what now happens. Video Clip: ds-neg10-buttons-loading-wrong.mp4 Heuristic: A01 Feedback How Reproducible?:Main page -> "Menü" (three strips in the upper left corner) -> "Herren" -> "Tracht" -> "Gilets" -> Click on "Sale" (white button) -> Click on "Sale" (now black button) again -> during the reloading of the page the "Neu" button gets visible again. o DS-Neg11 Title: Recall previous search requests from the search bar Description: The website does not save previous search request for the search bar. If a person searches for something specific, there could be a chance that they are interested in this type of clothing and might want to search for it again in the future. Video Clip: ds-neg11-recall-search-request.mp4 Heuristic: A07 Flexibility and Efficiency of Use How Reproducible?: Go to the main page and type a search request into the search bar at the top, for example "Adidas Socken". After the search completed, go back to the main page, and enter the search bar again. There are no previous search requests as recommendations for searching. Positive Findings ----------------- o DS-Pos01 Title: Filter options stays while scrolling Description: The option "Filtern&Sortieren", is used for selecting filters for the product list to achieve better search results. The option is on top of the search results, but during the scrolling process it stays on the screen and does not disappear when you scroll away from the top. So, you can easily adapt the filtering even when you are already scrolled down and search through the products. Video Clip: ds-pos01-filter-option-stays.mp4 How Reproducible?: Main page -> "Menü" (three strips in the upper left corner) -> "Herren" -> "Alle Artikel" --> Scroll down and you see, that the filtering option follows the scrolling o DS-Pos02 Title: Size table for size determination Description: If a user is not sure, which size of clothing he needs, then there is a size table option to determine your desired size. This option is put next to every size request so that the user is able to enter this option every time when he is unsure about which size he needs. In this size table are explanations how you should measure yourself and what these measurements correlate to in clothing size. Video Clip: ds-pos02-size-table.mp4 How Reproducible?: The size table can be found on the main page when you scroll down to the section "Kundenservice" and there is the option "Größentabellen" or if you click on an clothing item which is available in multiple sizes, then there is a option "Größentabelle" next to the size selector. o DS-Pos03 Title: Check for out of bounds orders Description: If you order an item, which is only available in a limited number anymore, then the system checks if you order exceeds this number and reduces the number to the max available number. If you try to increase this number again in the shopping cart menu, you will get an error message which clarifies why this is no longer possible. Video Clip: ds-pos03-out-of-bounds-check.mp4 How Reproducible?: Go to the main page and then to the sale section. Search for an item which is in limited stock (as of time of this logging and recording for example: COPENHAGEN Chelsea Boots CPH685) and order more as there are in stock. Afterwards go to the shopping cart menu (shopping bag icon on the right upper corner) and here you will see that only the possible number of items is in your shopping cart. If you increase the number of items here, you will get an error message and nothing will change in your order. o DS-Pos04 Title: Extra view for dressed items Description: In the product catalogue page, there is an extra option where the user can toggle between two different types of preview images. One is only the clothing item and the other one is a person wearing the item. This option stays next to the filtering option on top of the screen while scrolling. Video Clip: ds-pos04-extra-view.mp4 How Reproducible?: Main Page -> "Menü" (three strips in the upper left corner) -> "Neu" -> "Alle Artikel" -> Next to the filter option are two symbols, one shirt-symbol and one person symbol. These two buttons can be used to toggle between the two different preview image styles.
