Data Lakehouse Marketing

Now that everyone is slowly trickling back into work after what feels like endless summer vacations, it would be easy to give in to the temptation and dismiss the new buzzword "lakehouse" as a vacation memory or narrative - but watch out, it's not.

Even if summer vacations in the Swiss agency and marketing world are slowly taking on French dimensions, as described so beautifully and sarcastically by the author Frédéric Beigbeder in his 2001 novel "99 franc" (compulsory reading for young advertisers) and meanwhile last from the beginning of July to the beginning of September: You can't book a lakehouse on Airbnb, but rather it will (hopefully) fundamentally change marketing over the next few years.

If marketing would finally team up with technology

A data lakehouse is a data management architecture that combines the advantages of a traditional data warehouse and a data lake. Data warehouses were developed as early as the 1980s as high-performance storage tiers that supported so-called business intelligence (BI) and analytics independent of an operational transactional database. Data Lakes then came into vogue in the 0s because they were a cost-effective storage layer for unstructured and semi-structured data.

A data lakehouse now offers help thanks to easy access and support for enterprise analytics found in data warehouses, with the flexibility and relatively low cost of a data lake. Got it?

If not, they are part of the majority of Swiss marketers. And this is exactly the problem why Switzerland is still a developing country when it comes to marketing technology (martech). This is a pity, because the right use of martech not only offers almost endless possibilities to be creative, but also converts this very creativity into business-relevant results for the client.

Our industry would therefore do well if agency strategists, CMOs and CIOs perhaps cut their summer vacations a little short next year and instead thought together about a data lakehouse. That way, existing technology solutions would finally be understood as well, helping to leverage the multitude of opportunities for marketing purposes, from digital asset management and marketing automation platforms to chatbots and social media monitoring tools. Managing separate systems, as is unfortunately still the case in many companies, means not only investment costs, but also horrendous ongoing operating costs on both sides, not to mention the administration of two systems. And no one can afford that anymore. A lakehouse, on the other hand, can.

Report warns of deepfake attacks and cyber extortion

Multi-cloud services provider VMware has released its eighth annual Global Incident Response Threat Report.

Multi-cloud services provider VMware has released its eighth annual Global Incident Response Threat Report. This provides deep insight into the challenges security teams face in times of pandemics, burnout and geopolitically motivated cyberattacks. Sixty-five percent of security professionals say cyberattacks have increased since Russia's invasion of Ukraine, the report finds. The report also sheds light on new threats such as deepfake, attacks on APIs and cybercriminals targeting incident responders.

Bypass security controls with Deepfake

"Cybercriminals are now incorporating deepfakes into their attack methods to bypass security controls," said Gerd Pflüger, Systems Engineer for Network and Security Virtualization at VMware. "Two-thirds of respondents to our report experienced malicious deepfakes being used as part of an attack. This represents a 13 percent increase over last year, with email being the most common delivery method. Cybercriminals are no longer just using synthetic video and audio data for influence or disinformation campaigns. Their new goal is to use deepfake technology to compromise organizations and gain access to their environment."

Stress as a problem with security teams

In addition to the new risks, the report also points to other issues facing enterprise security teams:

  • Burnouts among cyber professionals remain a critical problem. Forty-seven percent of incident responders said they had suffered from burnout or extreme stress in the past 12 months. There is only a slight decrease here from last year's 51 percent. Of this group, 69 percent (down from 65 percent in 2021) of respondents have considered leaving their job because of it. However, companies are working to counteract this: more than two-thirds of respondents said their workplaces have implemented wellness programs to combat burnout.
  • Ransomware actors rely on cyber extortion strategies. The prevalence of ransomware attacks, often supported by the collaboration of cybercrime groups on the dark web, is still unchallenged. Fifty-seven percent of respondents have faced such attacks in the past 12 months. And two out of three respondents have encountered affiliate programs and/or partnerships between ransomware groups, as prominent cyber cartels continue to harm businesses through double coercion techniques, data auctions and extortion.
  • APIs are the new endpoint and represent the next frontier for attackers. As workloads and applications proliferate, 23 percent of attacks are directed at API security. The top types of API attacks include data spying (42 percent of respondents in the past year), SQL and API injection attacks (37 percent and 34 percent, respectively), and distributed denial of service attacks (33 percent). 
  • Lateral movements are the new battlefield. They were seen in 25 percent of all attacks, with cybercriminals using everything from script hosts (49 percent) and file stores (46 percent) to PowerShell (45 percent), business communications platforms (41 percent) and .NET (39 percent) to probe networks. An analysis of telemetry in VMware Contexa, a full-fidelity threat intelligence cloud integrated with VMware security products, found that in April and May 2022 alone, nearly half of the incursions contained a lateral movement event.

Successes in the fight against cybercrime

Despite the increasing threats detailed in the report, incident responders are demonstrating success, with 87 percent saying they are able to disrupt cybercriminals' activities sometimes (50 percent) or very often (37 percent). They are also using new techniques to do so. Three-quarters of respondents (75 percent) say they now use virtual patching as a contingency mechanism. In any case, the more overview defenders have of the ever-growing attack surface, the better equipped they are to weather the storm.

The interruptions to production during the Corona crisis, the blockade of the Suez Canal by the container ship "Ever Given" that lasted for days, the war in Ukraine and the global chip shortage have all shown that the economy must prepare itself for ever new disruptive factors. That means it must become resilient. Companies must be able to return to their original state as quickly as possible after the outbreak of a crisis, or - even better - emerge from it stronger.

How smart maintenance contributes to resilience

One important area in which manufacturing companies must respond to disruptions is the Maintenance. Their task is to ensure the production capability of machines and plants and to restore it as quickly as possible. Researchers from the Sustainable Production and Quality department at Fraunhofer IPA have therefore surveyed the current situation of maintenance with regard to resilience and worked out in a study how smart maintenance can also contribute to resilience in the future.

 

Great openness to digital services

To this end, the scientists conducted an online survey last year. Representatives of 34 companies of various sizes and industries completed the questionnaire in full. Their responses indicate, for example, that the majority of respondents consider resilience to be an important factor in ensuring that manufacturing companies continue to operate successfully in the future.

97 percent of respondents see personnel as the most important success factor in maintenance. Almost all of the professionals who took part in the online survey can imagine working with assistance systems such as "remote service" in the future. Many do not see their jobs in danger if sensor-based and self-learning maintenance technology is used in the future. Rather, they assume that digital services will supplement the skills of personnel, but not replace them.

Benefits of 5G have not arrived: Customer retention in the telecommunications industry is becoming more difficult

A global survey by Salesforce has identified current industry trends and customer needs in telecommunications. For example, the latest Trends in Communications Report 2022 shows that trust and customer satisfaction are currently at a very low level. Customer loyalty is proving to be a major challenge in this industry. Half of the respondents even believe that they need better service [...].

Telecommunications Industry trendsA worldwide survey by Salesforce has identified the current industry trends and customer needs in telecommunications. From the current Trends in Communications Report 2022  for example, shows that trust and customer satisfaction are currently at a very low level.

Customer loyalty is proving to be a major challenge in this industry. Half of the respondents even believe they will receive better service if they threaten to switch providers.

The current debate about the 5G rollout in this country as well as recurring service failures in a short period of time underpin the underlying skepticism about the industry. The traditional companies are now called upon to respond better to customer needs and to regain trust with transparent communication.

 5G benefits have not reached customers

New technologies such as 5G offer opportunities for providers, but the benefits have yet to be seen by potential customers. Fifty-three percent of respondents do not know that 5G offers better Internet coverage for underserved communities, and about three-quarters of respondents are unaware of the opportunities for real-time control of remote devices or the resulting benefits for the Internet of Things.

However, when detailing the benefits associated with 5G technology, more than two-thirds (67 percent) of respondents would be willing to pay more for it.

Discrepancy between self-perception and customer satisfaction

90 percent of employees at telecommunications providers believe that their company facilitates communication and solves customer cases faster than before thanks to digitized processes. But it's a different story on the customer side: Customers want more - especially when it comes to their online experience. Only 22 percent rate the tools and options for independent account management as excellent, and 40 percent are dissatisfied with their current provider.

However, it's not just the digital experience that counts, as personal customer service can be a key differentiator. Although 51 percent of customers said they preferred to do business online, 64 percent visited and used the provider's website. However, 40 percent of customers also visited the store during the same period. One-third of respondents (35 percent) preferred a hybrid service. However, only 25 percent of customers said in-store staff were knowledgeable, and only 23 percent said they received efficient service.

Green IT: Sustainable IT as the key to competitiveness

While the digitization of processes saves resources in individual companies, the global digital transformation leads to exponential resource use worldwide. There is a simple reason for this: Increasing virtual workflows are generating ever greater volumes of data that are stored in data centers - which produce more or less CO2 emissions depending on their size and constitution. Studies show [...]

While the digitization of processes saves resources in individual companies, global digital transformation leads to a global exponential resource use. There is a simple reason for this: Increasing virtual workflows are generating ever greater volumes of data that are stored in data centers - which, depending on their size and constitution, produce more or less CO2 emissions. Studies show that data center operations already account for 2 percent of the world's energy

It is all the more tragic when data is stored but neither analyzed nor used for the company's success. A "loose - loose" situation arises. The choice of storage location for data, the form of the data and the right data platform are therefore a decisive step both for corporate success and for preserving the environment. This lends immense importance to green IT, i.e., environmentally compatible information and communications technology (ICT) services and products and sustainable use.

Initiatives, measures and certifications

Measures such as the German government's Green IT initiative or the European Ecodesign Directive have succeeded in keeping electricity consumption by IT in Germany at least relatively constant since 2017 - around two percent of the country's electricity consumption. But blockchain technology or artificial intelligence (AI) are driving up the energy demand of data centers. According to a Study by The Shift Project of 2019, however, emissions from the digital economy could already account for eight percent of total CO2 emissions in the next five years. 

To counteract such scenarios, companies need to pay attention to their carbon footprint - especially in data centers. For example, a lot of energy can be saved in the cooling of servers, because lighting and outdoor cooling can be automated and the location of the servers also plays a role - as far apart as possible and in a cool place. Overall, a power consumption effectiveness of 1.2 or less should be targeted. In addition, many processes and applications can now be moved to the cloud. The energy supply for cloud systems tends to be lower due to the size scaling. In principle, companies can also pay attention to energy efficiency certifications when purchasing. Organizations such as TCO Certified or Energy Star, for example, test and certify factories and devices with regard to their efficiency and sustainable practices. 

What role does Green IT play in companies?

According to a Study by Capgemini However, green IT currently plays only a minor role in most companies - only one in five companies with a sustainability strategy takes the climate contribution of IT into account. This is due in part to a lack of expertise, according to a total of 53 percent of respondents. And only 43 percent of executives know the amount of CO2 emissions their IT generates. Only 18 percent have a comprehensive strategy with timelines and concretely defined goals; only 6 percent are already implementing sustainable IT. And this will not change in the next few years: only 22 percent of companies plan to reduce their CO2 footprint by more than a quarter through sustainable IT. And this despite the fact that Data centers worldwide are estimated to consume about 3 percent of electricity and are responsible for about 2 percent of total greenhouse gas emissions.

Sustainable data use determines competitiveness and staff attrition

Companies have recognized the relevance of sustainable business decisions based on data. According to a Study by Cloudera more than one-fifth (21 percent) of decision-makers in German companies are already putting greater investment in environmental, social and governance (ESG) ahead of developing new products and services (18 percent) or maintaining or increasing their profits (19 percent). This is not entirely altruistic, however, because in addition to the ecological necessity, the economic benefits of sustainable IT cannot be dismissed - both in terms of the bottom line and through social reputation, brand image and customer loyalty. 

The Cloudera study shows this in detail: when asked what the impact would be if their company did not start using data to make more sustainable business decisions over the next 3 years, nearly half of business decision makers (47 percent) said they expected growth to decline. Other consequences include increased pressure on the board and loss of business. Most interestingly, 27 percent of decision makers believe that employees will leave the company - a crucial criterion in times of skills shortages.

Innovative products through cooperation at eye level

Digitization is fundamentally changing the economy. Because it networks products and services, new business and organizational models are emerging.

is also changing user behavior and customers' understanding of benefits (perceived added value). Customers want new, usually more comprehensive solutions. Companies have to respond to the rapid change in order not to end up on the sidelines. They are forced to offer services outside their core business. Often, services from outside the industry must be included in a competitive, customer-oriented system offering.

Competition from lateral entrants

Mechanical engineering is also feeling the effects of the digital transformation process. Not only are the conventional value chains being
Companies are also facing competition from unexpected sources, from lateral entrants. One way out is cooperation between several companies that have different focuses or even cover different industries. Together, they are able to bring completely new products and services to the market. To offer a system portfolio for individual cell therapies, a company that manufactures machines for the pharmaceutical industry could join forces with various partners: for example, with specialists in cell diagnostics, with experts in regulatory affairs in the medical field, or with manufacturers of pharmaceuticals and with experts in analytics solutions based on artificial intelligence. In this way, an innovative product is created from the different competencies.

Cooperation requires new corporate culture

The white paper summarizes the results of a study on the topic of business ecosystems with 16 mechanical engineers and the findings of the dissertation by Richard E. Geitner
for the design of structural BES together. It is shown why the formation of a structural BES, especially in connection with a consistent customer orientation of companies, is a strategic option of a highly flexible value creation system for innovative cross-industry value and system offerings. The opportunities and specific characteristics of this form of cooperation are addressed.

It also outlines the basic procedure for designing a corresponding cooperation. However, structural BES requires a new corporate culture.
So far, cooperations have mostly been structured vertically: One company sets the direction, the others contribute. The new type of collaboration is based on equality. Each participant makes a substantial contribution to the joint product - and all participants benefit.

Despite risks: Advantages outweigh

Of course, cooperation at eye level also involves risks. Entrepreneurs must overcome their mistrust of other companies. They must not be afraid of their know-how falling into the wrong hands or of being taken advantage of by supposed partners. Overall, however, the advantages outweigh the risks. Not only can they offer innovative products and respond very flexibly to changing customer requirements. Investments are also halved - or even eliminated altogether - if the partner already has the necessary know-how. The mechanical engineering companies that took part in the study also see these advantages. More than 90 percent of them consider joint offerings to be "increasingly relevant".

YouGov LINK data products

As part of YouGov, LINK recently began offering its customers access to leading global data products and internationally representative survey pools. In addition to direct access to the products "YouGov Profiles", "BrandIndex" and "Global Profiles", it also provides direct access to the YouGov Panel with more than 20 million panel members worldwide.

In this way, Link aims to provide even more targeted advice to its clientele. In addition to these new options, Link will continue to offer a wide range of services - for example, the Link Panel will continue to be run independently of the YouGov Panel as Switzerland's only actively recruited online panel and will continue to provide the country's largest and highest-quality survey pool.

Despite the ongoing digitalization, there are also questions that can only be answered reliably through verbal communication between people, according to Link. For this reason, other survey options such as telephone interviews, qualitative interviews, group discussions or face-to-face surveys will of course continue to be conducted.

Link CEO Benedikt Lüthi

The adapted Link logo used from now on as part of the brand identity is intended to express this positioning and the expanded offering in an appropriate manner. Benedikt Lüthi, CEO Link and General Manager YouGov DACH, explains: "Our new appearance not only underlines our affiliation with YouGov as well as the well-known Link quality, but also the reality that the YouGov and Link teams are already working together for our customers."

The Internet is teeming with highly sensitive information. Sophisticated encryption techniques usually ensure that such content cannot be intercepted and read. But in the future, powerful quantum computers in particular could crack the keys, sometimes in a matter of seconds.

Method from the 1990s

Quantum mechanical key exchange - known in technical jargon as quantum key distribution (QKD) - is tap-proof against attacks on the connection lines. QKD is therefore also immune to quantum computers, but not to attacks or manipulation of the devices themselves. The devices could issue a key that the manufacturer had previously stored and possibly passed on to a hacker. The so-called "Device independent QKD", or DIQKD for short, now also checks the security of the devices. Theoretically, this method has been known since the 1990s, but now an international research group led by LMU physicist Harald Weinfurter (https://xqp.physik.uni-muenchen.de/people/professor/weinfurter/index.html) and Charles Lim from the National University of Singapore (NUS) was realized experimentally for the first time.

Measuring quantum states of atoms

In the present experiment, the physicists used two entangled rubidium atoms located in two laboratories 400 meters apart on the LMU campus to exchange keys. The two sites are connected by a 700-meter fiber-optic cable that runs under the plaza in front of the university's main building. To exchange a key, the two parties measure the quantum states of their atoms. This is done randomly in two and four directions, respectively. If the directions match, the measurement results are identical due to entanglement and can be used to generate a secret key.

Tap-proof connections thanks to quantum cryptography

A so-called Bell's inequality can be evaluated with the other measurement results. John Bell developed this inequality to test whether nature can be described with hidden variables. With the DIQKD, this test is now used to ensure that there is "no manipulation of the devices, i.e. that hidden measurement results have not already been stored in the devices," says Weinfurter. The NUS protocol now uses two measurement settings. "This makes it much more difficult to intercept information. More noise can be tolerated and secret keys can be generated even with higher noise levels," says Charles Lim.

"With our method, we can now securely generate secret keys even with uncharacterized and potentially untrusted devices," explains Weinfurter. "Our work lays the foundation for future quantum networks in which absolutely secure communication between distant locations is possible," says Charles Lim.

Develop inter- and multinational teams

Leading multinational teams

Just a few years ago, people primarily spoke of an intercultural or multicultural team when people from different cultures worked in a department of a company. Today, however, team members often live and work all over the world. In addition, fixed (work) teams have often been replaced by loose collaborations and temporary project groups. According to the statements of the Cross-cultural trainer Ulrike Fröhlich from Weil am Rhein, Germany has also changed the requirements in the area of team development. Whereas in the past, development measures were primarily required for fixed teams at one location, today the participants often work in different countries. So instead of cross-cultural training designed to make their German-speaking employees fit for business with Japan, for example, companies are planning (online) training "in which Japanese, Koreans and Americans participate in addition to Germans, Swiss and Austrians," reports the owner of the consulting firm Understanding Japan. Increasingly, "cooperation partners such as customers, suppliers or external service providers" are also taking part in the training courses.

Multinational teams: unfamiliar work for many

Cross-border, largely digital collaboration also causes problems. Some team members feel overwhelmed by this type of cooperation, in which people rarely, if ever, meet in person, reports Sabine Machwürth, co-owner of the consulting firm Machwürth Team International (MTI), Visselhövede (here is an older article from this company). And rightly so, "because when people from different cultures, who also live in different countries, work together, the need for coordination increases. It also increases the likelihood of misunderstandings."

This sometimes creates the impression that multicultural teams are per se more inefficient. According to Canadian organizational psychologist Nancy J. Adler, this is not the case. Her studies have shown: Culturally mixed teams have the potential to perform better than those in which all participants have the same cultural background; moreover, the different perspectives and approaches often result in better solutions.

Potential of teams often not exploited

However, this potential is often not called upon. For this to happen, patience is initially required, explains Sabine Machwürth, because: "It takes some time for a newly formed team to cooperate well." An initial phase of euphoria is usually followed by a phase of disillusionment - the so-called storming phase. Without external help, inter- and multinational teams often find it difficult to get out of this phase and into the third team development phase, known as norming.

The friction in the storming phase results from different ideas of how work should be done. For example, questions such as

  • "In what order should tasks be completed?",
  • "Who informs whom and when?",
  • "How are decisions made and communicated?" and
  • "How do we handle mistakes or problems?"

is answered very differently in the various cultures. If a team is unclear about this, there is often a great deal of uncertainty and mutual disappointment. According to Ulrike Fröhlich, this is particularly true for teams "in which people from cultures that tend to shy away from conflict, such as Japan, are expected to cooperate with people who tend to enjoy conflict, such as Germany.

Increase team spirit and performance

Below are some tips from Ulrike Fröhlich and Sabine Machwürth on what team leaders and members should consider and do to ensure that inter- or multinational teams ultimately reach the Performing phase, where they deliver top performance.

  1. Be curious and get to know each other personally. Talk to your cooperation partners about private topics as well. Finding common ground helps build trust, and trust is the basis for good cooperation.
  2. Talk about the differences in the way of working. It is important to explore and appreciate the other person's way of working. For example, as a team leader, conduct short workshops on "Getting to know and appreciate other ways of working."
  3. Note: There is no one, correct way of working. People who work successfully internationally usually not only accept that tasks can be solved differently, they also integrate elements of this into their working style. This makes them more cooperative and behaviorally flexible.
  4. Be open to new approaches and problem solving. See the encounter with what is new to you as an opportunity to leave the beaten track.
  5. Explore how to communicate well in a group setting. Communication in particular is sometimes very different in different cultures. Germans, for example, are known for addressing sensitive issues directly, while East Asians, for example, tend to approach them in a roundabout way. For this reason, everyone in the team should know what needs to be taken into account in the respective other culture, for example, when delegating tasks, giving feedback, and classifying information.

Brown Bag SeriesThe "Brown Bag Series" format launched in June by HWZ Hochschule für Wirtschaft Zürich, Swiss Marketing Forum and AZ Konzept is aimed at executives in marketing and communications and is intended to impart specialist knowledge at university level with practical relevance. In recent years, many companies have found that their marketing strategies are only partially suitable for situations in which the framework conditions change radically: Pandemic, war, problems in supply chains - hardly any company was really prepared for these challenges. At the same time, customers expect companies to deliver on their value propositions, take a stance on political and economic issues, and even optimize their performance with innovations. The talk will discuss how marketing strategies can be better aligned to uncertain times and how sustainable growth and innovation can be achieved even in this environment. The moderator is Esther-Mirjam de Boer, CEO and Owner of GetDiversity. Panelists are Tanja Herrmann, Managing Director of the influencer and social media marketing consultancy WebStages, Cécile Moser, Head of Marketing & Communication at Jelmoli and Tobias Thut, Head of Marketing & Sales, Member of the Executive Board of Pilatus-Bahnen.
The live stream will take place on Tuesday, August 23, from 11:00 a.m. to 12:00 p.m. Further information on the entire brown bag series can be found at the HWZ websitewhere you can also register for free.
